What Expansion Joint is Best for Plastic Pipe?

What expansion joint is best for plastic pipe?

Metraloops are an ideal expansion joint for plastic pipe. This is due to the low loads the loop exerts on the pipe. Flanged ends are preferred to prevent cracking of thin wall threaded fittings.

An alternative solution to the Metraloop is the 711 Plus. The 711 Plus is a full face rubber expansion joint with control rods integrated into the flanges on the joint. The integrated control rods prevent excessive stress from being transferred from the expansion joint’s flanges to the plastic flanges.
