Frequently Asked Questions

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

An OSG interrupted-thread pipe tap is used to cut internal NPTF threads in pipe and conduit fittings for leak-proof joints in hydraulic, pneumatic, and plumbing systems. The interrupted-thread design reduces cutting torque and improves chip evacuation in tough materials.

What are the specifications of the OSG 1 1/4"-11.5 NPTF pipe tap?

This OSG tap has a 1 1/4"-11.5 NPTF thread size, 5 flutes, and an interrupted-thread design. The manufacturer part number is 3312908. It is designed for threading pipe and conduit in industrial applications requiring NPTF dryseal threads.

Where to buy OSG pipe taps for worldwide delivery?

3G Electric supplies OSG pipe taps like the 1 1/4"-11.5 NPTF interrupted-thread tap (MPN 3312908) to customers worldwide. We handle full logistics, customs clearance, and delivery to your site, ensuring you get the right threading tool for your application.

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

Select an OSG pipe tap by matching the thread size (e.g., 1 1/4"-11.5 NPTF) and type (interrupted-thread for tough materials). Ensure the tap has the correct number of flutes (5 for this model) and is rated for the material you are threading, such as steel or stainless steel.
