Replacement 1.5" Inlet/Outlet Fitting for Pondmaster Pressurized Filters
This 1.5" threaded inlet/outlet fitting replaces worn or damaged connections on Pondmaster pressurized filters sized 2.7" to 8" in diameter. Stripped or cracked threads at the filter port cause slow leaks that worsen over time and compromise filter efficiency. Replacing this fitting restores a watertight seal without replacing the full filter housing.

Installation
Shut off the pump and relieve water pressure before removing the old fitting. Hand-thread the replacement fitting into the filter port until snug, then add a quarter-turn with a wrench. Do not overtighten. Apply thread sealant tape to NPT threads before installation. Restart the pump and check for leaks at the fitting shoulder before returning the filter to service.
Fits Pondmaster pressurized filter models from 2.7" to 8" diameter. Order by filter diameter to confirm the correct fitting size for your system.
