About Pipe and Fittings

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

Standard-Wall Butt-Weld Steel Unthreaded Pipe Traps

Butt-weld traps allow for a smooth connection that provides maximum flow. They have beveled ends that, when flush to pipe, create a trough for a strong, permanent weld. Traps are also known as Schedule 40. They are for use in noncorrosive environments.

Thick-Wall Butt-Weld Steel Unthreaded Pipe Traps

With thicker, stronger walls than our standard-wall butt-weld pipe traps, these traps stand up to your high strength applications. Weld them flush against pipe for a smooth connection that permits maximum flow. These traps have beveled ends that create a trough for a leak-resistant, permanent weld. Made of steel, they’re for use in noncorrosive environments.
