Pipe Fittings

More than 4,600 fittings across every joining method used in residential and commercial plumbing: press, sweat, threaded, solvent weld, no-hub, grooved and the PEX systems (F1960 expansion, F1807 crimp, F2159). Material follows the application — copper and brass for potable supply, ABS and PVC DWV for drainage, carbon steel for gas, cast iron for no-hub soil stacks.

Sizes run 3/8" through 12", concentrated where the work is: 1/2", 3/4", 1", 1-1/2" and 2". Tees, couplings, 90° elbows, reducers and male and female adapters make up most of the count, with reducing tees the single largest group.

Two things to check before ordering. Fitting size is nominal and follows the pipe, not the measured diameter. And press fittings are system-specific: a Viega jaw profile and a Mueller profile are not interchangeable, so match the fitting to the tool you own.

Plastic is three different systems and they do not cross over. PVC Schedule 40 and Schedule 80 are both pressure-rated and share an outside diameter; Schedule 80 has the thicker wall and the higher rating, which is why it is grey where Schedule 40 is white. PVC DWV and ABS DWV are drainage fittings and carry no pressure rating at all — they are shaped for flow, not for holding, and they never belong on a supply line no matter how cleanly they solvent-weld. CPVC is the plastic rated for hot water on the potable side. Cement follows the material too: PVC cement does not bond ABS, and a transition between the two takes an approved transition cement or a mechanical coupling.

Threaded pipe nipples are listed separately, in black iron, red brass, galvanized and 304 stainless from Close to 72": see Pipe Nipples.

Stocked brands include Mueller Streamline, Viega, Charlotte Pipe, Legend Valve and Tyler Pipe.
