Frequently Asked Questions

What is an OSG 1/8"-27 NPT pipe tap used for?

This OSG pipe tap creates internal NPT or ANPT threads in pipe fittings and conduit for leak-proof joints in plumbing, pneumatic, and hydraulic systems. Its 4-flute black oxide HSS design suits manual or machine tapping in steel, stainless, and cast iron.

What are the specifications of the OSG 1250501 pipe tap?

The OSG 1250501 is a 1/8"-27 NPT/ANPT short-projection spiral-flute pipe tap. It has 4 flutes, is made of black oxide high speed steel, and is designed for through-hole threading in industrial piping applications.

Where to buy OSG pipe taps in worldwide?

3G Electric supplies OSG pipe taps like the 1250501 to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this and other industrial threading tools.

How to select the right pipe tap for NPT threads?

For NPT threads, match the tap size to the pipe nominal diameter and thread pitch (e.g., 1/8"-27). Choose a spiral-flute design for through holes to clear chips. OSG's black oxide HSS taps offer good wear resistance in general-purpose steel and cast iron.
