Philmac Threaded Bushing – 1" x 3/4" | Step Down from 1" to 3/4" Thread in One Fitting

The Philmac Threaded Bushing 1" x 3/4" is a hex bushing that reduces a 1" female threaded (FNPT) fitting down to a 3/4" male threaded (MNPT) connection. It’s the simple, reliable solution for connecting 3/4" valves, fittings, or equipment to 1" threaded ports in your agricultural water system.

This is one of the most common thread size reductions in agricultural water systems — where 1" main connections frequently need to step down to 3/4" for trough valves, lateral lines, and other components. The hex body makes it easy to tighten with a standard wrench, and precise threading ensures a leak-free connection when used with thread sealant.
