Pipe Threads (PTF) are larger in diameter than most UNF or SAE-LT threads
and also provide additional strength. PTF threads have a taper like SAE-LT
threads to provide a “leakproof” installation. These threads are
designated by nominal pipe diameter. The 1/8 PTF thread is actually about
3/8” diameter, and the ¼ PTF thread is about ½” in diameter. A
tapped hole is required for installation. PTF fittings are used most often
in construction and in the agricultural industry.
