Frequently Asked Questions

What is the OSG 1/4"-18 NPT pipe tap used for?

The OSG 1/4"-18 NPT pipe tap is used to cut internal National Pipe Taper threads in metal pipes and fittings. Its interrupted-thread design reduces cutting torque and chip clogging, making it ideal for threading in tough materials like stainless steel and alloy steels in plumbing, hydraulic, and pneumatic systems.

What are the specifications of the OSG pipe tap MPN 1657004008?

The OSG pipe tap MPN 1657004008 has a 1/4"-18 NPT thread size, 3 flutes, interrupted thread design, and is made from V-coated cobalt steel. It is designed for taper pipe threading and is suitable for manual or machine tapping in industrial applications.

Where to buy the OSG 1/4"-18 NPT pipe tap worldwide?

You can source the OSG 1/4"-18 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 OSG cutting tool.

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

To select the correct OSG pipe tap, match the tap size to the pipe thread specification, such as 1/4"-18 NPT. Consider material hardness: use cobalt taps for tough alloys. The interrupted-thread design reduces torque and improves chip evacuation. Always verify the tap's flute count and coating for your application.
