Tubing
system, tubing should be considered as one
tTubing is assembled by simple wrench make-up on DK-Lok fitting. This results in less assembly and maintenance costs. tTubing assembly on DK-Lok fitting is re-usable. tTubing is bendable. It allows lower pressure drop with fewer connections. This in turn reduces system costs because of less fabricating manpower. tPipe threading or welding is difficult to disassemble and re-assemble tPiping requires skilled worker for welding & threading
Tubing Selection
Hardness tTubing must be softer than fitting material. The metal tubing must be fully annealed and suitable for bending and flaring. tTubing hardness must be selected according to the information in the table 2 to 13.
Surface tTubing must have a surface free from scratches, draw mark, dirt, dust and flat spots.
Ovality tTubing in oval or out-of-roundness way not fit into the fitting. Do not force the tubing into the fitting; it may damage the fitting sealing system on nut, ferrules, and body.
Wallthickness tThe table 2 to 13 list tubing working pressure ratings in a wide range of wall thickness. A too thin wall may collapse and a too thick wall may not properly be deformed by the ferrule action. tDo not use tubing wall thickness not listed in the table 2 to 13.
Weld tubing tWelded tubing should have a not measurable bead on its outside diameter.
Tubing Handling
Careful handling and storage practices will protect tubing from unnecessary scratches, nicks, or degrading the good tubing surface
tTubing ends should be capped so any foreign materials will not fall inside during transportation and storage. tDo not drag across tubing rack, cement, gravel or any rough surface. tDo use correct tube cutter for tube material. The wrong cutter may result in excessive deformation of the tube end. tDo not cut deep with each turn of cutting. tTube cutters and hacksaws should be sharp enough. tHacksaw blades should have at least 32 teeth per inch. tDo deburr tube ends before inserting in fittings.

DK-Lok Tube Fitting Pressure Rating
tThe pressure rating of DK-Lok Tube Fitting is rated to the working pressure of connective tubing. tThe allowable working pressure of tubing in various materials is listed in the table 2 to 13.

Material Material

ee sealing -

Gas Application
including gas leak proof and vacuum tight service. Gases (helium, hydrogen, nitrogen, air, etc.) can escape even the most minute leak-path due to their very small molecules. Tube therefore must be handled not to have scratches, draw mark,
Use NOT thin wall tubing for gas applications. Heavier wall tubing resists the ferrule action whereas thin walltubing may collapse with little resistance to ferrule action. For Gas service, use the tubing wall listed on un-shadowed section in table 2 to 13.
Vacuum Application
DK-Lok Tube Fittings have been proved to be excellent vacuum tight seal in many applications including analytical industry. DK-Lok Tube Fittings comply with the leakage requirements of TA-LUFT 2002.
Cryogenic Application
DK-Lok Fittings in SS316 Stainless Steel provide highly reliable performance on cryogenic application. Cryogenic temperature is considered to be temperatures below -100× (-73).
High Pressure Application
Pressure 500 psig (34.5 bar) or higher is considered generally high pressure. In the high pressure system scratches, draw mark, nicks,
. tFor gas application, select the gas applicable tubing wall thickness from Table 2 to 13. tFollow the suggestion on tubing selection, handling, and installation.

According to the requirements of ASME B31.3 Process Piping Code and ASME B31.1 Power Piping Code, allowable working pressure calculated at -20 to 100× (-28 to 37) using S value of 20,000 psi.
t Pressure calculations are based on maximum O.D. and minimum wall thickness and no allowance is made for corrosion and erosion. i.e., ASTM A269 1/2 in. OD x 0.035 in.WT: OD tolerance ± 0.005 in., WT tolerance ± 15%. Calculations are based on 0.505 in.OD x 0.0298 in. WT.
t Safety Factor is 3.75 to 1, considering ultimate tensile strength of 75,000 psi.

Weld Stainless Steel Tubing Allowable Working Pressure
To determine the working pressure of weld tubing to the requirements of ASME B31.3 Code, de-rating factors below must be applied. For single weld tubing multiply by 0.80, and for double weld tubing multiply by 0.85. Example: SS316 seamless 1/2 in. O.D. x 0.065 in. WT allowable working pressure: 4700 psi.
To determine the work pressure of the single weld tubing, multiply 4700 psi by 0.80. 4700 psig x 0.80 = 3760 psig at -20 to 100× (-28 to 37).

Temperature De-rating Factors
The pressure rating of DK-Lok port is governed by the connective tubing pressure rating. To determine allowable working pressure at elevated temperature, multiply working pressure by applicable factor shown in table 14.

Example: SS316 seamless tubing 1/2 in. O.D. x 0.065 in.WT at 700 °F. 4700 psig x 0.82 = 3854 psi. Allowable working pressure of SS316 seamless 1/2 in. O.D. x 0.065 in. WT is 3854 psi at 700 °F.

Pipe Thread Sealants
Pipe thread sealant for tapered pipe thread assembly is essential to ensure leak-free thread sealing. Sealant usually contains a lubricant. Thread sealant fills the voids between the threads and prevents thread galling.
Wrap PTFE tape clockwise from first thread. Do not overhang the first thread; the tape may get into the fluid system.

Thermocouple Connector
DMCT

Most DK-Lok male connectors can be bored-through thermocouple fittings except those fittings with small male thread like 1/8 in. To order, insert T in DMC male connector part number. Example: DMCT8-8N-S
DK-Lok bored-through fittings have no shoulder or sizing angle inside the body. This allows thermocouples or dip tubes to pass beyond the fitting male thread.
Assembly instruction 1. Position the length of thermocouple to pass through fitting male thread and hold
it to prevent shifting during assembly. 2. Wrench tightens the nut 1 1/4 turns from finger tight position, keeping the body
steady with backup wrench. Tighten the nut 3/4 turn for 1/8, and 3/16; 3, and 4mm Tube Fittings.

ISO Pipe Thread
The International Standards Organization prepares the ISO 228-1 and ISO 7-1 international standard to standardize the nomenclature of several international pipe threads.
ISO 228-1
ISO 228-1 represents internal and external parallel pipe threads where pressure-tight joints are not made on the threads. Compressing two tightening surfaces outside the threads or interposing a gasket seal will make the internal and external thread assembly pressure-tight joint.
ISO 228-1 standardizes the following internationalpipe threads. 1. BS 2779 (BSPP) 2. DIN-ISO 228/1 3. JIS B0202 (PF)

Sealing by compression against the face of the female threaded component.
Reference DIN 3852 Form A
See page on 9
for G end connection

A self-centering taper is constructed at male thread end. This taper centers a bonded gasket to seal up on the face of the female threaded component.
DGB: NBR inner ring bonded to carbon steel outer ring. DGV: FKM inner ring bonded to stainless steel outer ring.

Port 1

3
Port 2

Be aware that Port Connector consists of machined ferrule end, and tube stub end. These two ends require different installation.
Machined Ferrule End Refers to Fig. 1 & 2.
1. Remove the nut and ferrules from DK-Lok port 1. 2. Place the nut over the machined ferrule end of the port connector. 3. Finger-tighten the nut onto the port 1. 4. Wrench-tighten the nut 1/4 turn, keeping the body steady with a
backup wrench. tDo not tighten 1 1/4 turns. This is not the standard ferrule. tTightens 1/8 turn for 1/16, and 1/8 in.; 3, and 4mm Tube Fittings.

Tube Stub End Refers to Fig. 3.
1. Insert the tube stub end into the port 2 until it is bottomed on the shoulder of the body.
2. Finger-tighten the nut on port 2. 3. Wrench-tighten the nut 1 1/4 turns, keeping the port 2 body steady
with a backup wrench. tTighten the nut 3/4 turn for 1/16. and 1/8 in.; and 3, and 4mm Tube Fittings. tFor re-use, see re-assembly instruction.

DK-Lok Welding Information
DK-Lok weld ends are constructed to SCH. 80 or greater.
1. Remove the nut and ferrules from the DK-Lok port. tThis protects the nut and ferrules from weld heat. 2. Cover the DK-Lok port threads with a protective device such as DK-Lok Plug (DP). tThis protects threads and sealing surface on the DK-Lok port. tFinger-tighten the DP to use it many times.

3. Tack weld at four positions 90 degree apart. tThis holds the fitting in alignment and concentricity. 4. Complete the welding. 5. Remove the protective device and replace the nut and ferrules.

Di-electric tube fitting is designed to apply where electrical current flowing through a pipe or tubing line must be interrupted to protect instruments.

Di-electric Tube fitting is commonly used in the natural gas transmission station where installed on impulse lines ahead of stations. This fitting interrupts cathodic current flow while permitting full fluid flow.

GAS TRANSMISSION TYPICAL APPLICATION

Function
tThe insulation function is performed by thermoplastic insulators. tFKM O-ring and PTFE back up ring provide fluid containment function within the fitting. tDK-Lok twin ferrule system provides reliable sealing in the impulse line tubing.
Caution

This "NO wrenching label" is placed on the insulation section hex. This insulation connection must not be disconnected.

Operation on Pre-Swaging Tool

1. Clamp the DPS on the VISE steadily. 2. Install the DK-Lok nut, ferrules onto the tubing. 3. Insert the loose ferrules and loose nut installed tubing end into the DPS until it is bottomed on the shoul-
der of the DPS. 4. Finger-tighten the nut. 5. Scribe the nut at the 6 o'clock position. 6. Wrench-tighten the nut 1 1/4 turns to the 9 o'clock position.
tTighten the nut 3/4 turn to the 3 o'clock position for 1/16, 1/8, and 3/16 in.; 2, 3, and 4mm Tube Fittings.

Assembly on Fitting

7. Un-thread the nut. 8. Remove the tubing pre-swaged ferrules from the DPS.
tIn case the tubing is difficult to remove from DPS, gently rock the tubing back and forth. Do not rotate the tubing.

1. 2. Hand-tighten the nut. 3. Wrench-tighten the nut to the previously pulled-up position; at this point, a sharp rise in torque is felt. 4. Tighten slightly with a wrench.

Gap Gauge
DIG
This no-go gap gauge is useful tool to inspect the DK-Lok initially pulled-up.
Operation Instructions
On initial assembly, apply DK-Lok no-go gap inspection gauge to make sure that the make-up distance is sufficiently pulled-up.
Refer to Fig 1. 1.The gap gauge does not fit the gap between the nut and the body hex.
This ensures that the fitting is sufficiently tightened on initial assembly.
Refer to Fig 2. 2.The gap gauge fits the gap between the nut and the body hex.
The fitting requires an additional tightening.

INSTALLATION INSTRUCTIONS
This instruction applies to DK-Lok Tube Fittings as well as DK-Lok Z series Tube Fittings.

DK-Lok Tube Fitting

Tube-end preparation

Prior to installation, make sure to have tube-end cut 90 degree, and remove burrs from inside and outside tube ends. Use proper tube cutter and maintain a sharp cutting wheel on it.

Step1

Step2

tMake sure the nut finger-tight

Scribe the nut at the 6 o'clock position and wrench-tighten the nut 1 1/4 turns to the 9 o'clock position, holding the body with a back up wrench.
tTighten the nut 3/4 turn to the 3 o'clock position for 1/16, 1/8, and 3/16 in.; 2, 3, and 4mm Tube Fittings.

DK-Lok Installation for High Pressure or High Safety Applications
1. 2. Wrench-tighten the nut until the tubing dose not rotate by hand or moves axially in the fitting. 3. Scribe the nut at 6 o'clock position. 4. Wrench-tighten the nut to the 9 o'clock position, holding the body with a back up wrench.
t0OMZUVrn to the 3 o'clock position is required for 1/16, 1/8, and 3/16 in.; 2, 3 and 4mm Tube Fittings.

Refer to page on 77 for Gap GBVHF0QFration Instructions.

Re-Assembly Instructions
DK-Lok can be used many times. Prior to re-assembly, ensure the components are clean and free of defects. 1. Insert the ferrules swaged tubing into the body until the front ferrule seats firmly. 2. Hand-tighten the nut. 3. Wrench-tighten the nut to the previously pulled-up position; at this point, a sharp rise in torque is felt. 4. Tighten slightly with a wrench.

Tube handling during installation

Do not force the tubing into the fitting when it dose not smoothly go in. It may be a deformed oval.
T : Tube O.D. R : Radius L: Straight tube length In case tube bend is too close to a fitting, the bend section shall enter the fitting. This may not allow the tube to be bottomed in the fitting, resulting in leaks. Keep the proper straight length of tube as shown in the tables. tDo not bend a tube in the fitting. Use tube bender prior to installation onto fitting.
