OSG Interrupted-Thread Spiral-Flute Pipe Taps.

Frequently Asked Questions

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

This OSG pipe tap is used to cut internal NPTF threads in metal components for leak-proof pipe connections in hydraulic, pneumatic, and fluid-handling systems. The interrupted-thread design reduces cutting torque and chip clogging in tough materials like stainless steel and alloy steels.

What are the specifications of the OSG 1"-11.5 NPTF pipe tap?

The OSG pipe tap has a 1"-11.5 NPTF thread size, 4 flutes, interrupted-thread geometry, and a V-coated cobalt construction. The manufacturer part number is 1657108008. It is designed for through-hole or blind-hole threading in hard materials up to 40 HRC.

Where to buy the OSG 1"-11.5 NPTF pipe tap worldwide?

You can source the OSG 1"-11.5 NPTF 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 OSG cutting tool.

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

Select an OSG pipe tap based on thread size (e.g., 1"-11.5 NPTF), material hardness, and hole type. For tough alloys, choose a V-coated cobalt tap with interrupted threads to reduce torque. Always match the tap to the required thread class (NPTF) and use proper cutting fluid for best results.
