Pyplok® JIS fittings have all the benefits of a welded joint without the hazards associated with hot work. Available in sizes ranging from 06A to 50A JIS for low- and high-pressure systems. Pyplok® fittings come in all standard configurations (straights, 45° & 90° elbows, adapters, tees, reducers and flanged ends). Choose from a wide range of materials including carbon steel, stainless steel, duplex, super duplex, copper nickel (CuNi), and titanium. Pyplok® fitting configurations provide permanent ends or a combination of permanent and separable ends. There are two seals: an inner O-ring seal, which is the primary seal, and an outer O-ring seal, the environmental seal that prevents outside contaminants from entering between the pipe and the Pyplok® fitting. All fittings are made from bar-stock single forging (solid "no-weld" construction). Pyplok®’s unique non-metallic O-ring sealing characteristics make it ideal for gaseous as well as fluid systems.
