Brass Pipe Fittings (NPTF)

Pipe thread drawing

This connection is still widely used in fluid power systems, even though it is not recommended by the National Fluid Power Association (NFPA) for use in hydraulic applications. The thread is tapered and the seal takes place by deformation of the threads. Measure thread diameter and subtract 1/4- inch to find nominal pipe size.
