2.7.3.3 EPDM Sealing Element 2.7.3.4 FKM Sealing Element 2.7.3.5 HNBR Sealing Element
IM-MP 724992 0120 MegaPress

Viega MegaPress fittings are manufactured with a high-quality, shiny black EPDM (Ethylene Propylene Diene Monomer) sealing element installed at the factory. The molded sealing lips also seal pipe surfaces with slightly uneven surfaces. Sealing elements are inserted into the fitting using a H1 food grade lubricant registered with NSF and the USDA, and is approved for use under FDA 21 CFR. The EPDM sealing element possesses excellent resistance to aging, ozone, sunlight, weathering, environmental influences, and most alkaline solutions and chemicals used in a broad range of applications. The operating temperature of the EPDM sealing element is 0° to 250°F (-18° to 120°C).
Viega MegaPress FKM fittings are manufactured with a high-quality, dull black FKM (Fluoroelastomer) sealing element installed at the factory. The molded sealing lips also seal pipe surfaces with slightly uneven surfaces. Sealing elements are inserted into the fitting using a H1 food grade lubricant registered with NSF and the USDA, and is approved for use under FDA 21 CFR. FKM possesses excellent resistance to aging, ozone, sunlight, weathering, environmental influences, and oils and petroleum-based additives. Its superb resistance to high temperatures and petroleum based additives makes it ideal for seals and gaskets in solar, district heating, low-pressure steam, and compressed air system fittings. The operating temperature of the FKM sealing element is 14° to 284°F (-10° to 140°C). It can withstand heat spikes up to 356°F.
Viega MegaPressG fittings are manufactured with a yellow HNBR (Hydrogenated Nitrile Butadiene Rubber) sealing element installed at the factory. HNBR is widely known for its physical strength and retention of properties after long-term exposure to heat, oil, and chemicals. The molded sealing lips also seal pipe surfaces with slightly uneven surfaces. The unique properties attributed to HNBR have resulted in wide adoption of HNBR in automotive, industrial, and assorted high-performance applications. Sealing elements are inserted into the fitting using a H1 food grade lubricant registered with NSF and the USDA, and is approved for use under FDA 21 CFR. The operating temperature of the HNBR sealing element is -40°F to 180°F (-40°C to 82°C).

2.7.3.7 Viega Smart Connect Technology

1Identify an unpressed connection during pressure testing when water flows past the sealing element.

Viega Smart Connect technology provides the installer quick and easy identification of an unpressed fitting during a leak test. When the fitting is pressed, a secure, non-detachable, mechanical connection is created. Smart Connect technology provides the installer with an easy way to see connections that have not been pressed before putting the system into operation.

2Upon identification, use the press tool to press the fitting, making a secure leak-proof connection.

Testing for leaks using Viega Smart Connect is not a replacement for testing requirements of local codes and standards. If testing with compressed air, it is necessary to use an approved leak-detect solution.

3 Viega MegaPress connections are fast, flameless, and reliable.

2.8.2 Expansion
Pipelines expand with heat. Heat expansion is dependent on the material. Thermal expansion in installed systems generates stress on pipes and appliance connectors. Compensation must be allowed for expansion and contraction that may occur within the piping system. Expansion joints or mechanical expansion compensators may be used to alleviate these stresses. The following methods are effective:  Fixed and sliding hangers  Expansion equalization joints (expansion bends)  Expansion compensators
2.8.3 Exposure to Freezing Temperatures
Viega MegaPress systems with EPDM sealing elements can be installed in ambient temperatures down to 0° F. Viega MegaPress FKM systems with FKM sealing elements can be installed in ambient temperatures down to 14°F. The HNBR sealing element available with Viega MegaPressG fittings can be installed in ambient temperatures down to -40°F. Piping systems exposed to freezing temperatures must be protected per acceptable engineering practices, codes, and as required by the local authority.
2.8.4 Underground Installations
Viega MegaPress fitting systems are all approved for underground installations. However, installations must meet all state and local codes, including those for underground. Proper authorization must be obtained prior to installation from the local authority.
2.8.5 Concealed Spaces
The Viega MegaPress fitting system has been approved for use in concealed spaces. Specific performance tests were conducted to evaluate the fittings for use in concealed spaces. Concealed tubing and fittings shall be protected from puncture threats. The Viega MegaPressG fitting system has been examined according to the construction and performance criteria in the CSA requirement LC-4 and was found acceptable. Specific performance tests were conducted to evaluate the fittings for use in concealed locations.

2.8.6 Electrical Bonding

When properly installed, MegaPress fittings comply with Section 1211.15 Electrical Bonding and Grounding of the Uniform Plumbing Code. The mechanical press provides continuous metal-to-metal contact between fitting and pipe. The press ensures the continuity of the bonding through this contact.
A qualified electrician is responsible for ensuring electrical bonding is tested and secured.

DANGER! Electric Shock
An electric shock can cause burns, serious injury, and even death.  Because all metallic piping can conduct electricity,
unintentional contact with a live wire can lead to the entire system and components connected to it to become energized. Metal piping is not meant to conduct electricity.  A properly bonded system creates a safe path for electricity to travel so that the system can't be energized.  An unbonded or improperly bonded system can be a shock hazard.  Always ensure bonding is in accordance with local codes.
CAUTION!
Potential explosive hazard ­ MegaPressG The fuel gas system shall not be used as a grounding electrode for an electrical system.
CAUTION!
Pressure and electrical grounding  The fittings are for use with fuel gases and are intended
for the operating pressure 0-125 psi.  The fuel gas system shall not be used as a grounding
electrode for an electrical system.

2.8.7 Corrosion Protection 2.8.8 Deflection

Viega MegaPress fittings exposed to corrosive action, such as soil conditions or moisture, must be protected in an approved manner in accordance with NFPA 54 Section 404.8, NACE Standard RP0169-2002 Section 5, 2009 UPC Chapter 6 Section 609.3.1, 2009 UMC Chapter 13 Section 1312.1.3, or satisfying local code requirements. Care should be taken to select hangers of suitable material that is galvanically compatible with the piping system. In addition, systems should be properly sized to minimize the risk of erosion corrosion resulting from excessive velocities. In some cases the local authority may require pipe and fittings to be painted. Installers should use caution to prevent saturating the fittings with paint and take care to not allow excess paint to accumulate on the fitting hub. Failure to use caution could result in a premature failure.
The pressing process can cause deflection (angular misalignment) to occur. When pressing Viega MegaPress fittings in a system, the deformation of the fitting is constant. This allows for a consistent leak-free joint every time and is a result of the pressing technique. Deflection occurs in the same way for every fitting. The fitting being pressed will move in the direction of the jaw or ring opening.  Since the fitting will deflect toward the opening of the jaw or ring, the
pipe end will deflect in the opposite direction.  By counteracting the fitting movement, one can minimize the
deflection of the fitting and ultimately the pipe.  When using strut and clamps, deflection is minimized and nearly
eliminated depending on clamp spacing.

Product Information

2.8.8.1 Controlling Deflection

Deflection while pressing can be minimized by utilizing the following installation practices. Alternate sides for presses  Press one end of fitting.  Make second press on other end of fitting from the opposite side. Site conditions permitting.

Push-pull method  Rings = Push on press tool.  Jaws = Pull on press tool.
The press tool can be feathered using the trigger as needed to apply pulling or pushing force to control deflection. Re-Press  Press the fitting, once on each side (that is, re-press the fitting a second time on the opposite side). Pressing the same connection from the opposite side will usually straighten misalignment between the pipe and fitting.

 When pressing overhead piping, it may be inconvenient to alternate sides for each press.
 The natural weight of the piping plus pressing on opposite sides at a 45 degree angle should adequately eliminate deflection.
 This technique can also be used for any horizontal piping and also when working above the piping.

IM-MP 724992 0120 MegaPress

 As long as the pipe is properly prepped and marked and the fitting is installed according to Viega's MegaPress Product Instructions, if there is any deflection present after the installation of the fitting, the connection is still acceptable and meets Viega's manufacturing specifications for proper installation and warranty.
 Deflection of a press connection has no effect on the integrity of the system, and it can be pressure tested in accordance with the MegaPress Product Instructions.

Installation Instructions
4 Installation Instructions
4.1 Check System Components
System components may, in some cases, become damaged through transportation and storage.  Check all parts.  Replace damaged components.  Do not repair damaged components.  Contaminated components may not be installed.
4.2 Installing and Mounting the Pipe
Observe the general rules of hanging and mounting:  Fixed piping should not be used as support for other piping and components.  Do not use pipe hooks.  Observe distance between fittings and mounting points.  Observe the expansion direction ­ plan fixed and sliding mounts.
4.2.1 Pipe Hangers and Supports
Piping supports perform two functions:  To provide support for the piping.  To guide the pipe during thermal expansion and contraction.
Fittings must not be used as support
 System malfunction may result from additional stress and strain put on the fitting.
 At no point in the system should a fitting be the sole means of support. For example, when installing a tee, both the branch and the trunk must be properly supported.

26 of 46

IM-MP 724992 0120 MegaPress

Installation Instructions

Industry standard practices and guidelines shall be used for pipe layout and support. Supports, hangers, and anchors are to be installed in a manner that does not interfere with the free expansion and contraction of the piping. All parts of the support equipment need to be designed and installed to not disengage due to movement of the supported piping. Sliding hangers must be positioned so that they cannot unintentionally become rigid hangers when the system is in use.  Do not use fixed pipelines as a support for other pipelines and
components.  Do not use pipe hooks.  Observe the expansion direction: plan fixed and gliding points.

Hangers and supports must conform to the local code requirements. In the absence of local code requirements, hangers and supports should conform to ANSI/MSS SP 58 Pipe Hangers and Supports - Materials, Design, Manufacture, Selection, Application and Installation. Only pipe clamps with chloride-free noise insulation inlays should be used to secure the pipes.

4.2.2 Transition Fittings
4.2.2.1 Threaded Connections
4.2.2.2 Flange Connections
4.2.3 No-Stop Couplings

The Viega MegaPress systems can be joined with off-the-shelf threaded fittings. In this regard:  The threaded connection is made first.  The press connection is made second. This process avoids unnecessary torsion on the press fitting.

When using Viega flanges, bolt the flange end in place prior to pressing the fitting to the pipe.

No-stop couplings and extended no-stop couplings are often used to conduct repairs. Without a stop, these couplings can slide completely onto a pipe and allow a connection to be made in tighter spaces. Unlike fittings with an integrated stop that have a minimum insertion depth, no-stop couplings have minimum and maximum allowable insertion depths. Both the minimum and the maximum insertion depths must be marked and a line connecting the two marks. Drawing a line between the minimum and maximum insertion marks distinguishes a good connection on a no-stop fitting from a bad connection on a fitting with a stop.

Installation Instructions

4.8 Pressure Testing

Viega Smart Connect technology provides a quick and easy way for installers to identify connections that need to be pressed. Unpressed connections are located by pressurizing the system with air or water. Pressure test all installed pipe in accordance with local codes or, in the absence of local codes, in accordance with NFPA 54 or NFPA 58.
Smart Connect Testing  Testing for unpressed connections using Smart Connect
is not a replacement for pressure testing requirements of local codes and standards.  If testing with compressed air, use an approved leakdetect solution.
Water testing with Viega Smart Connect:  Use a range of 15 to 85 psi.  If an unpressed fitting is found, make sure the pipe is fully inserted
before completing the press.  If the initial test is successful, system may be pressure tested as
required up to 600 psi. Testing with air can be dangerous at high pressures. When air testing with Viega Smart Connect:  Use a range of ½ psi to 45 psi.  If an unpressed fitting is found, make sure the pipe is fully inserted
before completing the press.  If the initial test is successful, system may be pressure tested as
required up to 200 psi. Viega recommends air testing of gas systems at a minimum of ½ psi.
The installation, inspection, testing, and purging of the fuel gas system shall be in accordance with local codes or, in the absence of local codes, tested in accordance with the International Fuel Gas Code, NFPA 54/National Fuel Gas Code z223.1, the Uniform Plumbing Code, NFPA 58 or CSA B 149.1 as applicable.

4.9 Disposal

Separate the product and packaging materials (e.g. paper, metal, plastic, non-ferrous metals) and dispose in accordance with all national, state, and regional requirements.
