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 and alloy steels.

What are the specifications of the OSG 1/4"-18 NPT pipe tap?

This OSG pipe tap has a 1/4"-18 NPT thread size, 3 flutes, interrupted-thread design, and V-coated cobalt construction. The V coating provides wear resistance and heat dissipation for extended tool life in hard materials. MPN 1657507008.

Where to buy OSG pipe taps worldwide?

3G Electric supplies OSG pipe taps worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine OSG cutting tools like the 1/4"-18 NPT interrupted-thread tap (MPN 1657507008) to customers across machining, oil & gas, and maintenance sectors.

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

Select an OSG pipe tap by matching the thread size (e.g., 1/4"-18 NPT), material (cobalt for hard metals), and flute count (3 flutes for chip evacuation). Interrupted-thread taps reduce torque in deep holes. Always use proper tapping fluid and align the tap perpendicular to the workpiece.
