Stainless Steel Compression Tube Fittings

double-ferrules-stainless-steel-compression-tube-fittingsStainless steel compression tube fitting is made of 304/316 stainless steel, and is a mechanism used both to seal and to grip tubing. This stainless steel compression tube fittings consist of four parts: body, a front ferrule, a back ferrule and nut. The mechanical advantage and geometry of this kind of fitting produces a leaktight assembly in high-pressure, high-vacuum, and high-vibration applications. This fittings are used in oil & gas industries, petro chemicals, power plant, steel industries, chemical industries, pharmaceutical industries, fertilizers, hydraulic and pneumatic, marine and any process industry. Accommodate metric tube O.D ranging from 4 mm to 16 mm, inch tube ranging from 1/8″ to 1/2″; Accommodate thread types and sizes ranging from BSPT, BSPP and NPT 1/8 to 1/2.
