Notice: Due to damage caused by Hurricane Harvey to the petrochemical facilities in Texas, plastic pipe prices are extremely volatile and availability may become an issue. Prices shown on our site are for our current stock and subject to change. We reserve the right to limit quantities or cancel orders. This effects all types of plastic pipe and tubing.

Qest Compression Fittings

Qest compression fittings by Zurn can be used to connect gray polybutylene, PEX, CPVC or copper tubing in any combination.  These are one of the few fittings that can be used with gray polybutylene plastic tubing.  Polybutylene was often used in manufactured homes.

Fitting sizes listed are for the inside diameter of the tubing.  IE: The 1/2 Qest coupling is for 1/2 inside diameter tubing which is 5/8 outside diameter.
