China Stainless Steel Instrumentation Hydraulic Fittings Manufacturer–Swagelok Replacements
Stainless Steel Instrumentation Hydraulic Fittings consist of four parts: the fitting body, the nut, the front ferrule and the back ferrule. These double ferrule fittings are designed to provide a leak-proof and torque-free seal at the pipe connection.
Stainless steel instrument fittings are vital “joints” and “blood vessels” in modern industrial measurement and control systems, and their performance is directly related to system reliability and safety.
