High-Pressure Iron and Steel Socket-Connect Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings have heavy duty construction that stands up to high-pressure applications. They are for use in noncorrosive environments.

Tee Outlets


	Socket Connect Female × Butt Weld

Tee outlets allow you to create a tap anywhere along a pipe. They are also known as branch connectors and are comparable to Sockolet. To install, drill a hole in your pipe to match the fitting’s pipe size and weld in place.

Extreme-Pressure Iron and Steel Socket-Connect Pipe Fittings

Also known as Pressure Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer. They are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings are for use in noncorrosive environments.
