3/8X11/16-16 O-RING FACE SEAL CAP

Also Known As:

Cap , O-Ring Face Cap , Female O-Ring Face Cap , Seal Cap , Adapters  O-Ring Cap , Hydraulics Cap

O-ring face seal fittings include a precision groove in the face of the male fitting. Sealing occurs when an O-ring is trapped in the groove by a smooth flat flange that is clamped against the face with a nut or nut and sleeve. The flat flange may be formed or brazed onto the end of a tube, or is machined on a fitting. There are two SAE groove types:

• Type A: The original style A O-ring has no retaining ledge.

• Type B: The Type B groove has a retaining ledge (half dovetail) that improves O-ring retention. The Type B style is more commonly found and is a design improvement over the Type A
