About this item:
- 3/8" x 18 NPSF Intermediate HSS Tap - Goliath
- HSS Bright Finish NPSF Hand and Machine Intermediate Tap.
- Pipe taps are much shorter than a similar size of regular hand tap, but the design features are the same.
- Goliath HSS taps provide a high hardness to toughness ratio, compressive and tensile strength, good abrasion resistance and resistance to micro-chipping, ensuring a long tool life.
- National Pipe Straight Fuel (Dryseal) 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.
- Intermediate Taps have a lead of four threads and are used in most general purpose applications to cut a thread true to a pre-drilled pilot hole.
- Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
