Plumb Shop Div Brasscraft 453-316 Drain Reducing Adapter

Product Description

The PLUMB SHOP DIV BRASSCRAFT 453-316 is a white plastic drain reducing adapter designed to connect 1-1/2 inch O.D. drain tubing to 1-1/4 inch O.D. drain tubing in residential plumbing drain configurations. The 1-1/4 inch end inserts directly into a wall or floor drain pipe, while the 1-1/2 inch end accepts standard brass or plastic tubular drain components. The adapter ships with a nut and washers, providing everything needed for a complete slip-joint connection. Plumbers and DIYers install this fitting when upsizing or downsizing drain tube connections beneath sinks and lavatories without cutting or solvent-welding pipe.

This adapter is suited for under-sink drain assemblies in residential bathrooms and kitchens where a size transition is required between the fixture tailpiece and the branch drain or trap arm. It works with standard tubular drain systems in 1-1/2 inch and 1-1/4 inch O.D. sizes, compatible with both brass and plastic tubular plumbing components. The white finish blends with common plastic drain hardware commonly found in vanity and lavatory installations.

Installation Notes

Installation is performed by licensed plumbers or qualified DIYers working on residential drain-waste-vent systems. Shut off water supply and clear standing water from the trap before disassembly. Hand-tighten slip-joint nuts first, then snug with channel-lock pliers — do not over-torque plastic fittings. Verify the connection is leak-free by running water and inspecting all joints after assembly.
