Pipe Expansion Joints
Available301 products
Pipe expansion joints are flexible unions that connect sections of pipe in a system. They absorb expansion and contraction of the pipe system caused by temperature changes, as well as movement and misalignment caused by vibration and start-up surges from attached pumps and machinery.
Flanged Expansion Joints
Flanged expansion joints bolt to the mating flange of a pipe section for ease of installation. They provide extra protection against misalignment and start-up surges in attached pumps and machinery.

Threaded-Connection Expansion Joints for Vibration & Suction
Threaded-connection expansion joints withstand vibration and suction in pipe systems. The threading of the socket union absorbs and distributes vibration better than slip-socket or telescoping connections.

Telescoping Slip-Socket Expansion Joints
These slip-socket expansion joints have a telescoping piston that absorbs expansion and contraction. They minimize misalignment and are often used as a repair coupling. Slip-socket joints connect PVC and CPVC pipe with pipe cement and are used in applications that transfer chemicals.

Control Rods for Flanged Expansion Joints
Control rods bolt to the flanged edge of expansion joints to limit the amount of elongation or compression the joint can sustain, limiting damage to the joint. These rods must be matched to an expansion joint with a compatible manufacturer part number and bolt hole pattern.
