Cleveland C64132 Pipe Tap 3/8"-18 NPSF

This Cleveland pipe tap cuts internal threads for 3/8"-18 NPSF connections in pipe and conduit. It is designed for maintenance technicians and machinists who need accurate fuel-dryseal threads in steel or brass components.

4-flute high-speed steel

The four-flute high-speed steel body provides chip clearance and wear resistance for general-purpose tapping. The 1-1/16 inch thread length and 2-9/16 inch overall length suit standard through-hole and blind-hole depths, though very deep holes exceed its reach.

NPSF thread form for dryseal pipe connections

The NPSF thread form creates the interference fit required for pressure-tight joints without sealant, making this tap the specific choice for dryseal piping systems rather than standard NPT applications.

Questions about this item

Will the 3/8"-18 NPSF threads mate with my existing 3/8" NPT fittings?

NPSF uses straight threads that seal with a gasket, while NPT uses tapered threads that seal by interference; they are not interchangeable without an adapter.

How can I verify the tap is cutting correctly in my drill press?

The tap should produce clean, full-form threads at 18 threads per inch with four evenly spaced flutes clearing chips; measure the first few threads with a thread gauge to confirm 3/8"-18 NPSF pitch.

Does the C64132 come with the 0.5625 in drill bit needed for 75 percent thread depth?

The package contains only the high-speed steel pipe tap; the 0.5625 inch drill bit for 75 percent thread engagement must be purchased separately.
