Fittings play an important role in both plumbing and heating systems to connect pipe or tubing, or to adapt to different shapes or sizes. The type of fitting required depends on the installation or repair. Fittings include: elbows, unions, couplings, unions, reducers, tees, crosses, caps, plugs and nipples. We offer these fittings in a variety of materials, such as: copper, cast iron, brass, galvanized, PVC, and stainless steel. You may also choose from a wide selection of connection type, including: threaded, sweat, compression, flare, Propress, SharkBite push-fit and PEX. We also sell straight and coiled copper tubing, helping contractors and Do-it-Yourself homeowners complete their plumbing or heating project.
