2 in FNPT Malleable Iron Union

This Class 300 union connects two-inch female NPT pipe ends in steam, water, oil or gas service. It meets ASME B16.39 and ASTM A197 standards for pressure piping. The malleable iron body suits industrial and commercial plumbing systems. Installers who need a demountable joint on rigid pipe choose this fitting.

Fits standard Class 300 piping assemblies

The FNPT threads mate with matching male NPT nipples, valves or equipment without adapters. Its union nut allows the joint to be broken for maintenance without cutting pipe. The design frees up labour time during service intervals. Systems requiring frequent disassembly benefit from this arrangement.

Rated 600 psi at 150 °F and 300 psi saturated steam

The fitting withstands continuous operating temperatures from -20 °F to 450 °F. Pressure capacity follows the Class 300 rating curve across the temperature range. Malleable iron maintains structural integrity under sustained thermal cycling. It is not intended for pressures or temperatures beyond the published limits.
