Technical & Application
Material
Steel (hardened or self-colour) and stainless steel (A4)
Technical Notes
To DIN 906. NPT (National Pipe Thread Taper) and NPTF (National Pipe Taper Fuel).
The NPTF dry seal versions fit holes that are not as accurately tapped.
Tightening torque is dependent on fluid, pressure, temperature, and material pairing.
Tips
NPTF threads will screw together with NPT threads and should have no noticeable assembly problem. There will most likely be an interference fit between the root and crest on either the major or minor diameter of the thread, depending on which part is NPTF. To accomplish a seal on the joint, a sealant will be required.
NPTF threads are designed to screw together. They are designed to have interference at the roots and crests of the threads on both the major and minor diameters. This interference should cause no assembly problem. The thread deformation caused by the interference fit and the wrench tightening is designed to make a dry mechanical seal.
Important Notes
