Their 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. ssemblies can be used from high pressure to critical vacuum, within a wide range of temperatures. O-ring contained completely for maximum efficiency Gland Test ports at two locations for easy leak testing Smooth finish on gland face ensures positive seal Female nut threads silver plated for easy assembly Nut ody Technical ata Materials of onstruction omponent odies, glands, nuts utomatic tube weld fittings O-ring, bodies O-ring, S/MS threads Lubricant O-ring Uniform O-ring Uniform /8 and /4 00 3/8 and 3/4 6 25 S/MS Thread O-ring Uniform 7/6-20 904 9/6-8 906 3/4-6 908 /6-2 92 5/6-2 96 Material 36 SS 36L SS Fluorocarbon FKM (70 durometer) Fluorocarbon FKM (90 durometer) Silicone-based s ratings published in this catalog are calculated in accordance with SM 3.3, Process Piping. The listed pressure ratings are based on allowable stress values for temperatures up to 00 F (37 ). To determine pressure ratings in accordance with SM 3., Power Piping, multiply rating by 0.94. Temperature s Temperature ratings for fittings are determined by the O-ring materials used.
