Stainless Steel Socket Weld Union

Stainless Steel Socket Weld Union

Our Socket Weld Unions are high-pressure, three-piece fittings designed for systems that require frequent maintenance or dismantling. By providing a permanent socket weld connection on both ends, they offer a leak-proof seal with the added flexibility of a mechanical joint, allowing you to disconnect piping sections without cutting the line.
