Care should be taken not to con-
fuse the NPTF ftting with the
BSPT male ftting. NPTF fttings
have a 60° thread angle.
BSPT has a 55° thread angle.

North American Thread Types
This type of ftting uses the thread interface to seal and as such has a tapered
thread that deforms and forms the seal.
They have 30° sealing angle surfaces, forming a 60° inverted (concave) seat.
The fttings are most frequently seen on machines of US origin.
