Questions and answers of the customers

  1. A NPS = National Pipe Straight NPT = National Pipe ThreadBoth NPT and NPS have the same thread angle, shape, and pitch (threads per inch). However, NPT threads are tapered and NPS threads are straight (parallel). Both threads have a 60° included angle and have flat peaks and valleys.Tapered Pipe Thread is commonly found on ends of pipe, nipples and fittings (i.e. couplings, elbows, tees, etc.). Note: Sharply angled threads are very critical to joint being tight with no leaks. Thread sealant or tape is typically required to complete the seal. Straight Pipe Threads need a gasket or O-ring to create a seal.While NPT and NPS threads will engage, they do not seal properly with each other.
  2. A Different size combinations are available however these items are not stocked and the typical lead time for these products is about 1 - 2 weeks. Please call us for special orders and we'll let you know what we can do for timing and pricing. Thanks!
