Description
This is a description of a type of fitting used to seal the ends of hydraulic tubing. The fittings have a precision groove in the face of the male fitting, which allows an O-Ring to be trapped in the groove and sealed.
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. This product is manufactured by Midland.
