O-Ring Face Seal Fittings 3 Features Swagelok O-ring face seal fittings are designed for rapid assembly in pipe, tube, and welded systems. Unique design allows easy installation where space is limited. No axial clearance is required. Sealing is accomplished with a captive O-ring in the body component. O-ring contained completely for maximum efficiency Test ports at two locations for easy leak testing Female nut threads silver plated for easy assembly ody ssemblies can be used from high pressure to critical vacuum, within a wide range of temperatures. Gland Nut Smooth finish on gland face ensures positive seal Testing The face seal fitting design has been helium leak tested to a maximum leak rate of 4 0 9 std cm 3 /s.
