Frequently Asked Questions

What is the OSG 1657505008 pipe tap used for?

The OSG 1657505008 is a 1/8"-27 NPT interrupted-thread spiral-flute pipe tap designed for threading tapered pipe threads in hard materials. Its V-coated cobalt construction provides heat resistance and wear life, making it suitable for stainless steel and alloy machining in industrial plumbing and hydraulic applications.

What are the specifications of the OSG 1657505008 pipe tap?

The OSG 1657505008 is a 1/8"-27 NPT pipe tap with 3 flutes, an interrupted thread design, and a V coating on cobalt steel. It is manufactured under MPN 1657505008 and is intended for creating NPT tapered threads in tough materials. 3G Electric supplies this tool for global industrial procurement.

Where to buy the OSG 1657505008 pipe tap worldwide?

3G Electric supplies the OSG 1657505008 pipe tap worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time; we source and deliver this OSG tap to any country.

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

Select an OSG pipe tap by matching the thread size and pitch to your application—here, 1/8"-27 NPT. For hard materials like stainless steel, choose a V-coated cobalt tap like the 1657505008 with interrupted threads to reduce torque and chip binding. Always verify the tap's flute count and coating against material hardness.
