Stainless (316) Steel Compression Fittings

Stainless Steel Compression fittings have been designed and manufactured with great care to meet the specifications required for a wide range of applications in chemical, petro-chemical, oil refineries, power generation, ship building, pulp and papers, micro-electronics, etc.  Each fitting consists of four parts; body, front ferrule, back ferrule, and nut.  The two-ferrule design, front and back, compensates for any tolerances in tube O.D., wall thickness, material hardness and always ensures outstanding leak-tight connections.

When the nut is tightened, the back and front ferrules move axially.  This axial movement does not allow any torque transfer from the fitting to the tubing, and the mechanical properties of tubing are maintained.

During assembly, the back ferrule moves in such a controlled manner that the tubing is not overstressed, and the tubing I.D. is not excessively reduced, resulting in safe operation under high pressure or vibration.  The front ferrule does not force the body to expand, which allows the nut to be backed off easily for disassembly and allows the fitting to be used multiple times.
