EO-2 soft-seal bite-type fittings for metric tubing feature an EO-2 functional nut, which consists of the retaining ring and sealing ring pre-assembled in the nut. The sealing ring features a soft elastomeric seal which seals on the outside diameter of the tube and the 24-degree cone of the fitting body. The retaining ring bites into the O.D. of the tube to provide the holding power.
