NPS = National Pipe Straight. NPT = National Pipe Thread. NPTF = National Pipe Thread Fuel. Both 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.

11/1/2000· Several different tapered threads are made under the National Pipe Thread specifiion(s). NPT threads are tapered and obtain their ability to seal by forcing the threads together with this taper. Torque requirements are not often found because the threads are effective over a range of torques, that allows fittings to be positioned properly.

However, NPT threads are tapered and NPS threads are straight (parallel). Both threads have a 60° included angle and have flat peaks and valleys (this is a Sellers thread form). If you''ve worked with pipe much at all, you''ve probably noticed that the size of the pipe isn''t really what size the pipe is.

22/5/2020· Measuring pipe thread size to find the right thread type can be confusing. Thread dimensions are considered a nominal size and don’t match standard units of measurement. Using the proper pipe thread type is crucial for maintaining and installing equipment, so helping you determine what pipe thread you need is important to us. We have created a thread guide with five easy steps and …
NPT/NPS and BSP threads are not compatible due to the differences in their thread forms, and not just the fact that most sizes have a different pitch. NPT/NPS threads have a 60° angle and have flattened peaks and valleys (Sellers thread form) where as BSP threads have a 55° angle and have rounded peaks and valleys (Whitworth thread form).
NPSH or IPT refers to National Pipe Straight Hose or Iron Pipe Thread. NPSH is a straight thread and is popular on low-pressure water suction and discharge hose couplings. Compatibility: Male NPSH to NPSH, NPSM or NPSH or Male NPSH, NPT, NPTF and NPSM.
