Philmac Threaded Bushing – 1-1/2" x 3/4" | Large-to-Small Thread Reduction for Agricultural Water Systems

The Philmac Threaded Bushing 1-1/2" x 3/4" is a hex bushing that reduces a 1-1/2" female threaded (FNPT) fitting down to a 3/4" male threaded (MNPT) connection. Use it when you need to connect a 3/4" valve, fitting, or component to a larger 1-1/2" threaded port — a common requirement on main supply lines and large trough systems.

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. It’s a straightforward, reliable solution for bridging a significant thread size difference in your water system without replacing larger fittings.
