Frequently Asked Questions

What is the OSG 3/8"-18 NPT pipe tap used for?

This OSG pipe tap is used to cut NPT threads in pipes and fittings for industrial plumbing, hydraulic, and pneumatic systems. The interrupted thread design reduces cutting torque and chip clogging, making it suitable for through-hole threading in steel, stainless steel, and other alloys.

What are the specifications of the OSG pipe tap 1657509008?

The OSG pipe tap MPN 1657509008 has a 3/8"-18 NPT thread size, 4 flutes, interrupted thread geometry, and a V coating on cobalt steel. It is designed for high-speed threading in tough materials. 3G Electric supplies this tap globally.

Where to buy OSG pipe tap 1657509008 worldwide?

You can order the OSG pipe tap 1657509008 from 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 right OSG pipe tap for NPT threading?

Select an OSG pipe tap based on thread size (e.g., 3/8"-18 NPT), material (cobalt for hard metals), and flute count (4 flutes for balanced chip evacuation). The interrupted thread design reduces binding. 3G Electric can help source the correct tap for your application.
