BSPT (British Standard Pipe Thread)

NPT (National Pipe Thread)
NPT is the U.S acronym for tapered threads used on fittings and pipes that are, of course, tapered!
Taper threads pull tight to cause a seal.
Commonly used sizes with NPT are 1/8″, 1/2″ and 1/4″. NPT threaded fittings are part of our Ringlok twin ferrule compression fittings with various sizes for a number of tube applications.
NPTF (National Pipe Thread Fuel)
This type of thread is expertly designed for reducing leakage without use of a sealant such as PTFE tape.
Did you know? NPTF is also known as a Dryseal American National Standard Taper Pipe Thread.
