A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Class 3000 fittings, they have excellent strength to handle high-pressure applications.

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.
Socket connect x butt weld straight adapters are also known as half couplings.
