NPTF Taper Pipe Taps

NPTF (American National Taper Pipe Fuel) commonly called Dryseal taps are designed for pressure tight joints and must be assembled wrench tight with metal to metal contact of the entire thread profile to eliminate spiral leakage.

Interrupted Thread Taper Pipe Taps

Interrupted thread taper pipe taps always have an odd number of flutes to insure continuous engagement. Every other tooth is removed on each cutting edge to allow heavier chips to flush without packing while the tap is engaged.

Spiral Flute Taper Pipe Taps

Spiral flute pipe taps are recommended for use in soft and stringy materials where chips packing in the flutes are an issue. The high hook design coupled with the helical flutes lift long stringy chips out of the tapped hole.

BSPT Taper Pipe Taps

BSPT (British Standard Pipe Taper) 55 degree thread form taps produce an internal thread which joined with an external BSPT thread needs no sealant to produce a pressure tight joint
