Frequently Asked Questions

What is the OSG 1 1/2"-11.5 NPTF pipe tap used for?

This OSG pipe tap creates internal NPTF threads in metal for leak-tight joints in hydraulic, pneumatic, and plumbing systems. Its 7-flute design and black oxide coating reduce friction and improve chip evacuation in steel, stainless steel, and cast iron.

What are the specifications of the OSG 1313401 pipe tap?

The OSG 1313401 is a 1 1/2"-11.5 NPTF general purpose pipe tap with 7 flutes, made from black oxide high speed steel. It is designed for threading pipe and conduit in industrial applications requiring dryseal connections.

Where to buy the OSG 1 1/2" NPTF pipe tap worldwide?

3G Electric supplies the OSG 1313401 pipe tap worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine OSG cutting tools to facilities across 14 departments, including machining and maintenance.

How to select the correct OSG pipe tap for NPTF threads?

Match the tap size to the pipe nominal diameter and thread pitch—here 1 1/2"-11.5 NPTF. Use a black oxide HSS tap for general purpose threading in steel. Ensure the tap has the correct number of flutes (7) for chip clearance in deeper holes.
