Frequently Asked Questions

What is an OSG interrupted-thread pipe tap used for?

An OSG interrupted-thread pipe tap is used to cut NPTF threads in pipe and conduit fittings for leak-proof joints in hydraulic, pneumatic, and plumbing systems. The interrupted-thread design reduces cutting torque and improves chip evacuation in tough materials like stainless steel.

What are the specifications of the OSG 3312901 pipe tap?

The OSG 3312901 is a 1 1/4"-11.5 NPTF interrupted-thread pipe tap with 5 flutes. It is designed for threading pipe and conduit in industrial applications. OSG is a trusted brand for precision cutting tools, and 3G Electric supplies this genuine OSG tap worldwide.

Where to buy OSG pipe taps in worldwide?

3G Electric supplies genuine OSG pipe taps, including the 3312901, to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this interrupted-thread tap for NPTF threading.

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

Select an OSG pipe tap based on thread size, pitch, and material. For 1 1/4"-11.5 NPTF, use a 5-flute interrupted-thread tap like the 3312901 to reduce binding in tough materials. Ensure proper tapping speed and lubrication for clean threads. 3G Electric can help source the correct tap.
