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.

What are the specifications of the OSG 3/8"-18 NPTF pipe tap?

This OSG tap has a 3/8"-18 NPTF thread size, 5 flutes, and an interrupted-thread design. The manufacturer part number is 1311308. It is designed for cutting tapered pipe threads in steel, stainless steel, and other industrial materials.

Where to buy OSG pipe taps worldwide?

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

Select an OSG pipe tap by matching the thread size (e.g., 3/8"-18 NPTF), material type, and tap design. Interrupted-thread taps reduce torque in tough materials. For blind holes, use a bottoming tap; for through holes, a taper tap works. Consult OSG's technical data for guidance.
