Product Description

OSG Interrupted-Thread Spiral-Flute Pipe Taps.

Frequently Asked Questions

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

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

What are the specifications of the OSG 1/8"-27 NPT pipe tap?

This OSG pipe tap has a 1/8"-27 NPT thread size, 3 flutes, interrupted thread design, and V-coated cobalt construction. The manufacturer part number is 1657002008. It is designed for threading pipe fittings in industrial applications.

Where to buy OSG pipe taps worldwide?

3G Electric supplies OSG pipe taps worldwide, including the 1/8"-27 NPT interrupted-thread model. We handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this and other OSG tooling.

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

Select an OSG pipe tap by matching the thread size (e.g., 1/8"-27 NPT) and material. For tough alloys, choose cobalt with V-coating. Interrupted-thread taps reduce torque and chip buildup. Always use proper tapping fluid and follow manufacturer speed/feed recommendations.
