Covering the complete size range (from 6 (1⁄8″) to 50 (2″) NPT) in stainless steel with sizes up to 100 (4″) NPT available on request. Prochem offers only the highest quality fittings, and by utilising a reduced tolerance, ensures fittings will go together every time. This is the Prochem Standard and our stock throughout Australia conforms to the reduced tolerance to ensure customer safety.
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. Materials used comply with ASTM A403, A479 or A182 and are generally grade 316/L.
Fittings can be specially designed in accordance with ISO 9001 accreditation and manufactured to suit customers’ requirements in a variety of stainless and special alloys.
68,948 kPa (10,000 psi) NPT fittings are now available from Prochem.
