Extreme-Pressure Iron and Steel Threaded Pipe Fittings

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

Note: The maximum pressure listed for Class 6000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.

Extreme-Pressure Iron and Steel Threaded Pipe Flanges

Also known as Pressure Class 1500 flanges, these have the strength to handle high pressures. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges are for use in noncorrosive environments.

Forged Flanges


Front	Raised Surface on Back

Forged flanges have better strength than cast flanges.
