Installation Suggestions: Husky HD 2000 Heavy Duty No-Hub Coupling

Purpose

These suggestions provide guidelines for the use of Anaco HUSKY® HD 2000 Coupling for joining No-Hub pipe and fittings in accordance with accepted industry standards and practices. All construction projects involve many variables. Governing codes, engineering criteria, and the conventions of the plumbing trade necessitate that judgment decisions must be a combination of design and “on the job” considerations. The following suggestions for joining No-Hub pipe and fittings with the Anaco Husky HD 2000 coupling are not definitive but it is hoped that they will be helpful.

Installation Instructions

A properly calibrated torque wrench set at 80-inch pounds to accommodate the 5/16" hex head screw should always be used when installing HUSKY® HD 2000 couplings. When power tools are used to install HUSKY couplings they should be adjusted or calibrated to torque only to 80-inch pounds.

1. In order to provide a sound joint with field cut lengths of pipe, the ends should be cut square. Place the neoprene gasket on the end of one pipe and the stainless steel clamp assembly on the other end of the other pipe or fitting to be joined.
2. Firmly seat both ends of the pipe/fittings against the internally molded shoulder in the center of the gasket.
3. Slide the clamp assembly into position centered over the gasket.
4. HUSKY HD 2000 couplings 1.5", 2", 3" and 4" are three inches wide and have four sealing bands. Tighten bands to 80-inch pounds in the following sequence. Starting on the side of the joint with the smaller OD (see diagram “A”) torque as follows: 2, 1 - 2,1 - 3,4 - 3,4 - 2,1 - 3,4
5. HUSKY HD 2000 couplings 5"-10" are four inches wide, 12” and 15" are 5½" wide and have six sealing bands. Tighten bands to 80-inch pounds in the following sequence. Starting on the side of the joint with the smaller OD (see diagram “B”) torque as follows: 3,21 - 3,2,1 - 4,5,6 - 4,5,6 - 2,1 - 4,5,6.
6. Typically, once the coupling is installed and torqued to 80-inch pounds in this torque pattern, this is all that is necessary. Couplings may be re-torqued to confirm that all bands have been properly torqued to 80-inch pounds, following the proper torque pattern. Use caution as multiple torquing events may result in clamp failure.

Bracing

Horizontal pipe and fittings five inches and larger must be suitably braced to prevent horizontal movement. This must be done at every branch opening or change of direction by the use of braces, blocks, rodding or other suitable method to prevent movement or joint separation.

Product Identification

Anaco has intentionally color coated the HUSKY® HD 2000 304 Stainless Steel Shield. The white shield identifies this product as a genuine Anaco HUSKY HD 2000 Heavy-Duty coupling. HUSKY's performance, including its exceptional sealing ability, corrosion resistance, deflection and rigidity has not been compromised in any way.
