Frequently Asked Questions

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

This OSG pipe tap is designed for threading pipe and conduit connections in industrial piping systems. The interrupted-thread design reduces cutting torque and chip buildup, making it suitable for threading NPT fittings in steel, stainless steel, and other ferrous materials. It is commonly used in plumbing, hydraulic, and pneumatic applications.

What are the specifications of the OSG 1205300408 pipe tap?

The OSG 1205300408 is a 3/8"-18 NPT pipe tap with 5 flutes, an interrupted-thread design, and a V-coated cobalt construction. The V-coating provides wear resistance and heat dissipation for extended tool life in hard materials. The interrupted thread helps break chips and reduce binding during threading.

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

Select an OSG pipe tap based on the thread size and material. For 3/8"-18 NPT threads in hard materials like steel or stainless steel, use a V-coated cobalt tap with interrupted threads to reduce torque and chip clogging. Ensure the tap matches the NPT taper and has the correct number of flutes for chip evacuation.
