JF. 5i 17/22 6200 Canoga Ave #205, Woodland Hills, CA 91367 Project Architect Husky HD -2000 Submitral Heavy -Duty Couplings Engineer Contractor Date Husky HD -2000 Couplings The HUSKY HD -2000 coupling has been engineered to provide superior sealing while accommodating potential dimensional disparities in the mating of cast iron no–hub pipe and fittings. This has been accomplished through the use of a thicker, specially–designed corrugated shield of sufficient width to accommodate additional surface–bearing sealing clamps, torqued to 80in-lbs. These additional clamps result in a more uniformly rigid joint, with the load supported at both the outer edge of the coupling and the centerline of the joint. These clamps also yield increased surface–bearing contact, thereby inhibiting joint movement at higher internal pressures. uP[ Material Specifications Clamps: Type 304 AISI stainless steel. 4 clamps on sizes 1-1/2"-4', 6 clamps on sizes 5"-10" Screws: Type 305 AISI stainless steel 5/16" hex head Shield: Type 304 AISI stainless steel corrugated. Shield thickness 0.010" Gasket: Genuine neoprene as the primary elastomer, conforming to ASTM C564. Oil immersion rest: 80% maximum volume change after immersion in ASTM oil No. 3 for 70 hours at 212'F Suggested Specification No–Hub couplings shall be of the heavy-duty variety, with shields and bands made of Series 300 stainless steel, and gaskets made of genuine neoprene as the sole elastomer. 1-1/2" through 4" couplings shall have a minimum of four clamps, and 5" through 10" couplings shall have a minimum of 6 clamps. Couplings shall be installed in conformance with the manufacturer's installation instructions and local code requirements. Meets ASTM C 1540, ASTM C564, FM 1680 Class 1, CSA B 602.

Mission's Band -Seal' Specialty Coupling is a shielded transition coupling designed to connect similar and dissimilar pipe sizes and materials. Coupling consists of two (2) or four (4) 301 series stainless steel worm drive clamps, a 300 series stainless steel shield, over a molded one-piece elastomeric sealing gasket. C Series couplings are available in sizes 1112" to 6": 3" to 4" sizes utilize two (2) clamps; 5" to 6" sizes utilize four (4) clamps. Leak -Proof Seal - Stainless steel clamps provide a positive seal when properly tightened to 60 in/lbs. of torque. Sealing "O" Rings are installed under each sealing clamp to prevent pipe slippage and create a more positive seal, ensuring a water -tight, leak -proof and root -proof seal. Corrosion Resistant - 300 series stainless steel components provide highly effective corrosion resistance in a variety of environments. .38 .19 D30 Joint Movement Restraint - The Band -Seal- Specialty Coupling provides for superior load bearing control between the coupling and pipe surface. The coupling's rugged construction provides excellent sealing properties, and the stainless steel shield offers excellent resistance to shear forces and helps with alignment, while maintaining flexibility. Internal Pipe Stop - For proper pipe positioning and noise/vibration reduction. Pre -Set Calibration - All Band -Seal' Specialty Couplings are designed to be installed with a pre-set torque wrench calibrated to 60 in/lbs. maximum to accommodate the 305 series stainless steel S/,s' hex head screw.
