Frequently Asked Questions

What is the OSG 1657516008 pipe tap used for?

The OSG 1657516008 is a 1"-11.5 NPT interrupted-thread spiral-flute pipe tap used for threading pipe fittings in steel, stainless steel, and high-temperature alloys. Its interrupted-thread design reduces cutting torque and chip clogging, making it ideal for through-hole and blind-hole applications in industrial piping systems.

What are the specifications of the OSG 1657516008 pipe tap?

The OSG 1657516008 is a 1"-11.5 NPT pipe tap with 4 flutes, interrupted thread design, and V-coated cobalt construction. It is designed for threading NPT pipe threads in tough materials. The V-coating provides wear resistance and lubricity for extended tool life in production environments.

Where to buy the OSG 1657516008 pipe tap worldwide?

3G Electric supplies the OSG 1657516008 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 international destination.

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

Select an OSG pipe tap based on thread size, pitch, and material. For 1"-11.5 NPT threads in hard alloys, the OSG 1657516008 with interrupted thread and V-coated cobalt is suitable. Ensure the tap matches the hole type (through or blind) and use proper cutting fluid to extend tool life and achieve clean threads.
