Our NPT fittings are designed for high-pressure (class 3000 - class 6000) applications, and have a distinctive profile for maximum strength.As with our BSP range, all NPT products are checked with calibrated gauges during the manufacturing process and each batch is further confirmed as being in compliance with the international thread standard.
Before they are released into the market, each item is subject to a final visual HEXAGON HEAD PLUGS and dimensional inspection by thread profiling. Materials used comply with ASTM A403 or A182. For an approximation of working pressures please refer to charts on pages 24 and 25. Pressures are based on schedule 160 for class 3000 and XXS for class 6000.
Fittings can be specially manufactured to suit customers’ requirements in a variety of stainless and special alloys. 10,000 PSI NPT fittings are now available from Prochem.
