Goliath NPSF (Dryseal) Intermediate HSS Bright Pipe Tap: 1/8"
SKU: A0201190 | Model: B81ZKCB4
Diameter 1/8". Goliath NPSF (Dryseal) Intermediate HSS Bright Pipe Tap
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.
