Frequently Asked Questions

What is the OSG 1"-11.5 NPT pipe tap used for?

This OSG pipe tap is used for threading tapered pipe threads in metal, typically for creating NPT connections in plumbing, hydraulic, and pneumatic systems. The interrupted thread design reduces cutting torque and improves chip evacuation in tough materials like stainless steel and alloy steels.

What are the specifications of the OSG 1"-11.5 NPT pipe tap?

This OSG pipe tap has a 1"-11.5 NPT thread size, 4 flutes, interrupted thread design, and is made from V-coated cobalt steel. The manufacturer part number is 1657008008. It is designed for threading tapered pipe threads in hard materials, offering durability and chip control.

Where to buy the OSG 1"-11.5 NPT pipe tap worldwide?

You can source the OSG 1"-11.5 NPT pipe tap through 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 on this item.

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

Select an OSG pipe tap based on thread size (e.g., 1"-11.5 NPT), material compatibility, and tap design. For tough materials, choose a cobalt steel tap with interrupted threads and V coating, like this model, to reduce torque and improve chip evacuation. Always match the tap to the specific NPT standard.
