Our steel pipe fittings come in many configurations such as 5404 male pipe hex nipple, 5000 female pipe coupling, 5404N seamless pipe nipple, and many more. These pipe fittings have NPTF threads, which stands for American Standard Taper Pipe Duel Dryseal Thread, that are designed to screw together and cause interference at the roots and crests of the threads.
