Selecting the right option
Goliath NPT and BSPT pipe taps are available in taper, intermediate, and bottoming styles — taper for starting the thread, intermediate for continuing, and bottoming for threading to the bottom of a port. Confirm the pipe thread standard (NPT or BSPT) and the nominal pipe size before ordering.

Goliath NPT Taper HSS Bright Tap: 1/2"
SKU: A0199241 | Model: C84YJA4
Diameter 1/2". Goliath National Pipe Tapered (NPT) Taper HSS Bright Tap
HSS Bright Finish NPT Hand and Machine Taper 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.
Tapered Pipe Taps are used for tapered threading by hand or machine.
National Pipe Tapered (NPT)is a US standard for tapered threads used to join pipes and fittings.
ANSI/ASME standard B1.20.1 covers threads of 60º form with flat crests and roots.
The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other.
However, a clearance remains between the crests and roots of the threads, resulting in a leakage around this spiral.
This means that NPT fittings must be made leak-free with the aid of thread seal tape or a thread sealant compound.
For each 12" increase in distance from the end, the diameter increases by 3/4".
Taper Taps have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
Manufactured from HSS this general-purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
