Information

Socket Weld Cap 1 1/2'' SW A350 LF2 Class 3000 is a forged high-pressure fitting designed to permanently seal the end of a pipe in Socket Weld (SW) piping systems. The pipe is inserted into the socket and welded, creating a strong, leak-tight, and permanent joint suitable for demanding pressure applications.

Socket Weld fittings are widely used in high-pressure piping systems where safety, durability, and reliability are essential. Each fitting is permanently marked with its size, material grade, heat number, and pressure class for full traceability.
