Product Description

OSG Interrupted-Thread Spiral-Flute Pipe Taps.

Frequently Asked Questions

What is the OSG 1/2"-14 NPT interrupted-thread pipe tap used for?

This OSG pipe tap is designed for threading tapered pipe threads in metal, typically for creating leak-proof joints in plumbing, hydraulic, and pneumatic systems. The interrupted-thread design reduces cutting torque and chip clogging, making it suitable for tough materials like stainless steel and alloy steels.

What are the specifications of the OSG pipe tap MPN 1657512008?

The OSG pipe tap has a 1/2"-14 NPT thread size, 4 flutes, interrupted thread geometry, and a V coating on cobalt steel. The V coating enhances wear resistance and tool life. It is designed for through-hole or blind-hole threading in hard materials.

Where to buy the OSG 1/2"-14 NPT pipe tap worldwide?

You can source the OSG pipe tap MPN 1657512008 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.

How to select the correct OSG pipe tap for NPT threading?

Select a pipe tap matching the NPT thread size and pitch, such as 1/2"-14. For hard materials, choose a cobalt steel tap with a wear-resistant coating like V coating. Interrupted-thread taps reduce torque and are ideal for deep or interrupted cuts. Always verify the tap's flute count and geometry for your application.
