Frequently Asked Questions
What is the OSG 1/2"-14 NPTF pipe tap used for?
This OSG pipe tap is used to cut internal NPTF threads in metal components for leak-proof pipe connections in hydraulic, pneumatic, and fluid-handling systems. The interrupted-thread design reduces cutting torque and chip clogging in tough materials like stainless steel and alloy steels.

How to select the correct OSG pipe tap for NPTF threads?
Select an OSG pipe tap by matching the thread size (e.g., 1/2"-14 NPTF) and material. For hard or abrasive materials, choose a cobalt or V-coated tap like the 1657106008. Interrupted-thread taps reduce torque and are ideal for deep or blind holes. Always verify the tap's flute count and coating for your application.
