Frequently Asked Questions

What is an OSG 1/8"-27 NPT/ANPT pipe tap used for?

This OSG short-projection spiral-flute pipe tap creates internal NPT or ANPT threads in pipe fittings and conduit. It is designed for through-hole threading in steel, stainless steel, and cast iron, commonly used in plumbing, hydraulic, and pneumatic systems.

What are the specifications of the OSG 1250508 pipe tap?

The OSG 1250508 is a 1/8"-27 NPT/ANPT short-projection spiral-flute pipe tap with 4 flutes. It is made from TiCN-coated high-speed steel (HSS) for wear resistance and is designed for through-hole threading in industrial piping applications.

How to select the right pipe tap for NPT threads?

Select a tap matching the thread size and pitch, such as 1/8"-27 NPT. For through holes, use a spiral-flute tap like this OSG model to clear chips. Ensure the tap material (e.g., TiCN-coated HSS) suits the workpiece material. Consult OSG's technical data for optimal speeds and feeds.
