316 SS Instrumentation Compression Fittings

PVFPro's 316L Stainless Steel Double Ferrule Compression Tube Fittings are engineered for high-pressure instrumentation, process, and analytical systems. Available in Tube Union, Union Elbow, Union Tee, Male Connector, and Female Connector configurations across 1/4", 3/8", 1/2", and 3/4" tube OD sizes.

Double ferrule compression fittings create a leak-tight, vibration-resistant seal without welding or flaring. The front ferrule forms the primary seal against the tube OD; the back ferrule grips and supports the tube. Installation requires hand-tightening plus 1-1/4 turns — no special tools required. Rated to 6,000 PSI for 1/4" through 1/2" sizes.

316L stainless steel provides superior corrosion resistance in chemical, pharmaceutical, oil and gas, water treatment, and high-purity applications. Low carbon content minimizes carbide precipitation across the full service temperature range of -65°F to 1200°F.
