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.
