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.

Used to Join - C Series couplings are used to join cast iron to cast iron, plastic or
steel for C 315, C 320 & C 420; and cast iron to cast iron in remaining products.
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.

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.
