Weld Adapter

The Weld Adapter is a heavy-duty instrumentation fitting designed to provide a permanent, leak-proof transition between tubing and a system’s piping or pressure vessels via a welded connection. It typically features a smooth, unthreaded tube stub on one end—designed to be gripped by a standard double-ferrule compression fitting—and a weldable end on the other, which can be configured for either a socket weld or a butt weld application. This adapter is essential for high-temperature, high-pressure, or high-vibration environments where a rigid, permanent joint is required to ensure maximum system integrity and safety. Forged from high-grade materials like 316 stainless steel or carbon steel to match the parent piping, these adapters are widely used in power plants, refineries, and chemical processing facilities to connect instrumentation lines to main process headers.
