Stainless Steel Compression Fittings

Stainless steel compression fittings connect metal tube within pneumatic systems. Which stainless fitting is right for your planned use will depend on your tube’s connection style, thread type, pipe size, and thread size, as fittings and tube must be compatible for effective pneumatic operations.

How Stainless Steel Tube Compression Fittings Work

Each fitting consists of four parts: body, front ferrule, back ferrule, and nut. The two-ferrule design compensates for any tolerances in tube OD, wall thickness, and material hardness to ensure outstanding leak-tight connections. When the nut is tightened, the back and front ferrules move axially, preventing any torque transfer from the fitting to the tubing while maintaining the mechanical properties of the tubing. During assembly, the back ferrule moves in such a controlled manner that the tubing is not overstressed, and the tubing ID is not excessively reduced, resulting in safe operations 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 repeated use.
