Swagelok 316-HIA Fitting

Swagelok 316-HIA Fitting is a 316 stainless steel Swagelok tube fitting designed to create a secure, leak-tight connection in instrument and process piping when used with Swagelok ferrules and nuts. The designation 316 indicates 316 stainless steel, known for corrosion resistance in many chemical environments. This fitting is part of Swagelok’s broad line of tube fittings and adapters, built to join tubing in a two-piece assembly that uses a ferrule-based seal to form a reliable connection. Swagelok tube fittings are offered in sizes from 1/16 to 2 inches (2 to 50 mm), enabling standard tubing to be used across applications. Pressure ratings for Swagelok fittings vary by configuration, with documented working pressures ranging roughly from 1,900 psi (130 bar) up to 60,000 psi (4,134 bar) depending on design and end connections. Typical uses include instrument lines, chemical processing, and oil, gas, and pharmaceutical systems where corrosion resistance and dependable sealing are required.
