Parker’s Weld-lok® Series of permanent socket weld and butt weld tube fittings meet the most exacting requirements of any system. In contrast to general purpose weld fittings, the Parker weld fittings have the ability to directly connect to a tubing system with either single or two ferrule compression tube fittings. These 316 stainless steel fittings are a one piece adapter that makes a weld connection to a removable compression connection where removal may be necessary. These weld fittings are made from ASTM/ASME close grain forgings and bar stock. They are designed in accordance with ANSI B 16.11, which covers “Forged Steel Fittings Socket Welded and threaded”. Parker’s design parallels the Schedule 80, 3000 pound fitting pressure class, and is compatible with O.D. tube wall thickness meeting the related (3000 pound pipe class) pressure requirements. Weld-lok® Fittings conform to ANSI B31.1, ANSI B31.7, and Section III of the ASME Boiler and pressure Vessel Code to meet customer industry requirements.
