The 1/2" SW × 1/4" BSP Reducing Socket Weld Coupling 304L Class 3000 belongs to the group of high-pressure Socket Weld fittings, where the pipe is inserted into the socket before welding. The welded socket creates a strong, leak-tight connection. The Socket Weld (SW) system ensures safety, durability, and permanent pipe joints. SW fittings make it easy to select the correct pressure class for the installation.

Each fitting is permanently marked with its size, material grade, heat number, and pressure class. All Socket Weld fittings are available with a 3.1 material certificate.
