About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Low-Pressure Galvanized Iron and Steel Threaded Pipe Fittings

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Galvanized Iron and Steel Slip-On Framing and Fittings

To provide corrosion resistance in wet environments, this framing is galvanized. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Tighten the included set screws for a secure hold.

Galvanized iron fittings are malleable iron.

Caps

Caps protect and cover the ends of rails.
