Frequently Asked Questions

What is the OSG 1311300 pipe tap used for?

The OSG 1311300 is a 3/8"-18 NPTF interrupted-thread tap designed for threading pipe and conduit in steel, stainless steel, and non-ferrous materials. Its interrupted-thread design reduces cutting torque and improves chip evacuation, making it ideal for through-hole and blind-hole applications in industrial piping systems.

What are the specifications of the OSG 1311300 pipe tap?

The OSG 1311300 is a 3/8"-18 NPTF pipe tap with 5 flutes and an interrupted-thread design. It is made from high-speed steel (HSS) and has a manufacturer part number of 1311300. This tap is designed for threading pipe and conduit to NPTF standards, ensuring a pressure-tight seal.

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

To select the correct OSG pipe tap, match the thread size and pitch to your application—here, 3/8"-18 NPTF. Ensure the tap material (HSS) suits the workpiece. For pressure-tight joints, use NPTF taps like the OSG 1311300. Always verify the tap's flute count and interrupted-thread design for chip control in your material.
