What is it???

Swage Technology

Swaging is the controlled uniform reduction of the fittingend over the tube whereby forces are applied equally; 360

degrees around the fitting. The result of swaging creates a permanent connection between the fitting and tubing by plastically deforming them together as an assembly. Theswaging process also controls the elastic rebound of thetube within the fitting bore to create a sound mechanicalconnection and permanent fluid containment seal.

What is Permaswage ?

Permaswage fittings are radial

compressed (mechanically) onto compatibletubing to provide a permanent joint withmetal to metal sealing. The joint is effected

by differential springback between the tubeand fitting.

What is PermaLite ? PermaLite is a tube fitting that is mechanically

attached to the tube by axial swaging. Themovement of the ring along the fitting body

results in deformation of the tube with a leak-tight joint
