Compression Fittings — Stirlings Performance Steels

Stainless Steel Compression Fittings

Tube Compression Fittings create a reliable, leak-free connection using a three-piece design: a body, a nut, and a ferrule (or sleeve/olive). When the nut is tightened, the ferrule compresses onto the Tube, gripping and creating a seal against the fitting's body.

Stirlings stocks a range of Compression Fittings, including Female Connector BSP Thread, Male Connector BSP Thread, 90 Degree Bend, Double Clamp, Single Clamp, Bulkhead Union, Bulkhead Union Male, Union and Tee Fittings.

Compression Fittings are available in sizes from O.D 6.35mm (¼ inch) to 19.05mm (¾ inch).
