Frequently Asked Questions

What is the OSG 1/16"-27 NPT pipe tap used for?

This OSG pipe tap is used for cutting internal NPT threads in pipes and fittings for sealing connections in plumbing, hydraulic, and pneumatic systems. Its interrupted-thread design reduces cutting torque and chip clogging, making it suitable for through-hole threading in steel, stainless steel, and other ferrous materials.

What are the specifications of the OSG pipe tap MPN 1657502008?

The OSG pipe tap MPN 1657502008 has a thread size of 1/16"-27 NPT, 3 flutes, interrupted thread design, and is made of V-coated cobalt steel. It is designed for NPT pipe threads and is suitable for manual or machine tapping in industrial applications.

Where to buy the OSG 1/16"-27 NPT pipe tap worldwide?

You can source the OSG 1/16"-27 NPT pipe tap worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this and other OSG cutting tools.

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

To select the correct OSG pipe tap, match the thread size (e.g., 1/16"-27 NPT) and material to your workpiece. For harder materials like stainless steel, choose a cobalt or V-coated tap like this model. Ensure the tap has the correct flute count and interrupted thread design for chip evacuation and reduced torque.
