1/8" x 27 NPSF Bottoming HSS Tap
HSS NPSF Bottoming Hand and Machine Tap.
National Pipe Straight Fuel (Dryseal) is a variation of the Dryseal thread.
It is used for internal threads and an NPTF external thread can be screwed into it to provide both a satisfactory mechanical connection and hydraulic seal.
A combination of a parallel and tapered thread would not appear to be ideal but it is widely used.
Many quick disconnect couplers for example have the NPSF thread and are recommended by the manufacturer for use with NPT and NPTF.
Bottoming Taps have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole.
Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
