Stainless Steel Fittings

Stainless steel fittings remain the most popular fitting used on standard HPLC systems today, due to their high temperature resistance and high-pressure holding abilities. Our durable and strong 316 Stainless Steel Fittings are rated to 20,000 psi (1,380 bar) when wrench tightened.

Stainless steel fittings should not be installed in plastic ports. The recommended torque to tighten these fittings is 20 in-lbs (2.25 N·m).

You can choose our Standard Fittings, or select from other manufacturer-compatible offerings.
