Sloan Valve 306146 Spud Coupling Assembly Chrome

Product Description

The SLOAN VALVE 306146 is a spud coupling assembly designed to secure flushometer connections at the fixture interface in commercial restroom plumbing systems. The assembly includes a flange, slip joint gasket, and friction ring, working together to create a sealed connection between the flushometer and the fixture drain outlet. Sized at 1.5 inches by 3 inches with a chrome finish, it suits standard commercial installations where consistent sealing and a clean appearance are both required. Licensed plumbers and commercial plumbing contractors install this component as part of routine flushometer service or new fixture rough-in work.

The 306146 is intended for commercial restroom environments where Royal-series Sloan flushometers are installed on water closets or urinals. It is suited for high-use institutional settings such as schools, hospitals, office buildings, and public facilities. The chrome finish integrates with exposed trim for a uniform appearance. This assembly is commonly specified during fixture replacement, flushometer rebuilds, or when the original spud coupling shows wear, corrosion, or seal failure that causes leakage at the fixture connection point.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply to the flushometer and relieve line pressure before disassembling the existing spud coupling. Inspect the fixture spud thread and drain collar for damage before installing the new assembly. Do not overtighten the coupling nut, as this can distort the slip joint gasket and cause leakage.
