Information

The 1" BSPT A350 LF2 Class 3000 Coupling is a high-pressure threaded fitting designed for demanding industrial applications. The BSPT tapered thread provides a reliable and leak-tight connection for pressure piping systems. Each coupling is permanently marked with its size, pressure class, material grade, heat number, and thread type.

A350 LF2 carbon steel is a low-alloy steel widely used for forged fittings, valves, flanges, and piping components intended for low-temperature service. It combines excellent weldability with high mechanical strength and reliable performance in pressure applications.
