Frequently Asked Questions

What is the OSG 1251800 pipe tap used for?

The OSG 1251800 is a short-projection spiral-flute pipe tap designed for threading 3/8"-18 NPTF pipe and conduit in metal. It is commonly used in plumbing, hydraulic, and pneumatic systems to create leak-resistant threads in steel, stainless steel, and other ferrous materials.

What are the specifications of the OSG 1251800 pipe tap?

The OSG 1251800 is a 3/8"-18 NPTF pipe tap with 4 flutes, made from high-speed steel (HSS). It has a short-projection spiral-flute design for efficient chip evacuation. The manufacturer part number is 1251800, and it is designed for threading pipe and conduit in industrial applications.

Where to buy the OSG 1251800 pipe tap worldwide?

You can source the OSG 1251800 pipe tap worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply OSG cutting tools to customers across multiple industries.

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. Use a short-projection spiral-flute tap like the 1251800 for through-hole threading in steel. Ensure the tap material (HSS) suits the workpiece hardness. Consult OSG's technical data for optimal speeds and feeds.
