About this item:
- 1/2" x 14 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.
