Frequently Asked Questions

What is the OSG 1"-11.5 NPT/ANPT pipe tap used for?

This OSG pipe and conduit thread tap is used to cut internal NPT or ANPT threads in pipe fittings, couplings, and conduit. It is designed for threading in steel, stainless steel, and other ferrous materials in industrial plumbing, hydraulic, and pneumatic systems.

What are the specifications of the OSG 1252901 pipe tap?

The OSG 1252901 is a 1"-11.5 NPT/ANPT short-projection spiral-flute pipe tap with 5 flutes. It is made from black oxide high-speed steel (HSS) for improved lubricity and wear resistance. This tap is suitable for through-hole threading in rigid materials.

Where to buy the OSG 1252901 pipe tap worldwide?

You can source the OSG 1252901 pipe tap through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this and other OSG threading tools.

How to select the correct pipe tap for NPT threads?

Select a tap that matches the nominal pipe size and thread pitch, such as 1"-11.5 NPT. For through holes, use a spiral-flute tap like this OSG model to evacuate chips forward. Ensure the tap material (e.g., HSS) suits the workpiece hardness. Always use proper cutting fluid.
