The double ferrule compression tube fitting consists of four precision-engineered parts designed to provide secure leak
proof joints capable of satisfying high pressure, vacuum & vibration application. The four parts are body, front ferrule, back
ferrule & nut.
Fittings are supplied complete & ready for use. As the nut is tightened, the front ferrule swages onto the tube as it moves
down the cone of the body creating a prominent leak-proof seal on both tube and body by the interface pressure and surface
finish of mating components. The super case back ferrule then deforms inwards in the cone of the front ferrule, forming into
the tube & creating a strong mechanical hold on the tube.
The internal diameter of the body & nut are closely controlled diameters, which constrain the tube within in a close tolerance
of its axis ensuring accurate alignment within the assembled fitting.
