Expansion Joints

for trouble-free vertical installation.

Expansion Joints

These one-piece expansion joints allow for

thermal expanstion and contraction of drain, waste

and vent (DWV) and inside rain water conductor

systems. There are no sliding parts to malfunction,

no packing to jam, freeze or leak. They eliminate

costly offsets normally used to accommodate

expansion and contraction.

These leakproof, maintenance-free, distortion-free

joints have internal stops for positive positioning.

Available in 1½", 2", 3", 4".
