PERMCO 1-1/2 X 11-1/2 PIPE TAP

Description & Features

Designed for use with Permco hydraulic gear pumps and motors, this 1-1/2 x 11-1/2 pipe tap is a service and repair tool used to cut or clean internal threads in pump housings and port fittings. The 1-1/2-inch diameter and 11-1/2 threads-per-inch specification corresponds to standard NPT thread geometry, making it suitable for working with the threaded port connections common in Permco units.

The Permco 1-1/2 x 11-1/2 Pipe Tap is a manufacturer-matched tool, ensuring thread form compatibility when servicing or restoring port threads on applicable Permco equipment. Sourcing a brand-matched tap reduces the risk of thread mismatch during repair work on hydraulic gear pump assemblies.

Question by: Ralph M on Jun 28, 2025, 6:12 PM

What size pipe does this tap work with?

Answer by: Customer Support on Jun 30, 2025, 6:32 AM

It's made for tapping 1-1/2 inch pipe.

Question by: Carl B on Sep 16, 2025, 6:38 AM

what's this tap sized for exactly, is it a standard 1-1/2 inch pipe thread?

Answer by: Customer Support on Sep 18, 2025, 6:43 AM

Permco lists this as a 1-1/2 x 11-1/2 pipe tap, so yes, it cuts a 1-1/2 inch pipe thread at 11-1/2 threads per inch. That matches the standard NPT thread spec for that pipe size, which is what you'd expect when tapping ports in hydraulic pump housings or manifold blocks that use 1-1/2 inch pipe fittings.

got a permco pump housing that needs threads cut, is this the right tap size for 1-1/2 pipe

Answer by: Customer Support on Jun 29, 2025, 6:18 PM

For 1-1/2 pipe threads, the size you’re matching is 1-1/2 x 11-1/2, and that’s exactly what this Permco pipe tap is.
