Frequently Asked Questions

What is the OSG 1657511008 pipe tap used for?

The OSG 1657511008 is a 1/2"-14 NPT interrupted-thread spiral-flute pipe tap designed for threading tapered pipe threads in metals. It is commonly used in plumbing, hydraulic, and pneumatic systems to create leak-proof connections in steel, stainless steel, and other alloys.

What are the specifications of the OSG 1657511008 pipe tap?

The OSG 1657511008 is a 1/2"-14 NPT pipe tap with 4 flutes, interrupted thread design, and V-coated cobalt construction. The V coating reduces friction and extends tool life in hard materials. It is manufactured by OSG under MPN 1657511008.

Where to buy the OSG 1657511008 pipe tap worldwide?

You can source the OSG 1657511008 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.

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, such as 1/2"-14 NPT. For hard materials like stainless steel, choose a V-coated cobalt tap like the 1657511008. Ensure the tap has interrupted threads for chip clearance in through-hole threading.
