Typically used with extreme-pressure stainless steel unthreaded pipe fittings.

Typically used with high-pressure iron and steel threaded pipe fittings. Also known as Schedule 160.

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings.

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.
