Plumbing

Fittings and rough-in parts for water, gas and hydraulic lines: brass, PEX, copper, PVC and CPVC, valves and drains.

Sort by Category

Material is usually decided by the line you are tying into and what the system carries — brass and copper for potable water, black iron for gas, plastic where corrosion or cost matters. The pipe fitting material guide walks through the trade-offs, and the thread guide covers NPT, BSPP and JIC if you are matching an existing thread.
