Clamp-On Expansion Joints for Drain, Waste, and Vent
- For Use With: Air, Water
- Temperature Range: -30° to 130° F
- Maximum Pressure: 4 psi @ 72° F
These joints are designed for vertical use to reduce stress, vibration, and noise in drain, waste, and vent systems. Slip them over the end of your pipe and tighten the band clamps for a secure hold. They have an internal stop to ensure pipe is in the proper position.

Clamp-On Expansion Joints
- For Use With: Calcium Chloride, Oil, Petroleum, Sewage, Sludge, Sodium Carbonate (20% in Water), Water
- Temperature Range:
Neoprene Rubber: -20° to 220° F
Silicone Rubber: -75° to 500° F - Maximum Pressure: 150 psi @ 72° F
- Maximum Vacuum: 20 in. of Hg @ 72° F
Slip these joints over your pipe ends and tighten the band clamps for a secure hold. Joints have a triple-bulb design that provides excellent vibration absorption to reduce stress on your piping system. They also have reinforcing rings for extra support during pressure surges and in vacuum applications.
Neoprene rubber joints are more abrasion resistant than silicone rubber joints.
