What Are SS 304 Instrumentation Tube Fittings?

SS 304 Instrumentation Fittings are mechanical tube connectors made from austenitic stainless steel (AISI 304) and are used to join, branch, or adapt tubing lines in instrumentation and fluid systems. These fittings rely on a ferrule-based compression seal—either single or double ferrule—to ensure a gas-tight and vibration-resistant connection without welding or threading.

They are ideal for moderate pressure and temperature environments where both corrosion resistance and economical performance are key.
