Product Description

OSG Interrupted-Thread Spiral-Flute Pipe Taps.

Frequently Asked Questions

What is an OSG interrupted-thread pipe tap used for?

An OSG interrupted-thread pipe tap is used to cut internal threads in pipe fittings for gas, water, or steam lines. The interrupted-thread design reduces cutting torque and chip clogging, making it ideal for threading tough materials like stainless steel or alloy steel in industrial plumbing and hydraulic systems.

What are the specifications of the OSG 1/2"-14 BSPT pipe tap?

The OSG pipe tap has a 1/2"-14 BSPT thread size, 4 flutes, interrupted-thread geometry, and a V-coated cobalt construction. The manufacturer part number is 1658504008. It is designed for through-hole threading in pipe applications requiring high wear resistance and chip evacuation.

Where to buy OSG pipe taps worldwide?

You can source OSG pipe taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on the OSG 1/2"-14 BSPT interrupted-thread tap (MPN 1658504008).

How to select the right OSG pipe tap for threading?

Select an OSG pipe tap based on thread standard (e.g., BSPT), size, material, and tap geometry. For tough materials like stainless steel, choose a V-coated cobalt interrupted-thread tap to reduce torque and improve chip control. Always match the tap to the hole type (through or blind) and use proper cutting fluid.
