Oatey PP557W Extension Coupling Elbow 45 Degree 1-1/2 in

Product Description

The OATEY PP557W is a 45-degree plastic extension coupling elbow designed for drain line connections in residential plumbing applications. This fitting accepts a 1-1/2 inch connection and ships with a reducing washer that steps down to 1-1/4 inches, giving the installer flexibility when connecting to either standard 1-1/2 inch or 1-1/4 inch drain outlets. The plastic construction resists corrosion and keeps weight low for overhead or under-sink installations. A licensed plumber or skilled DIYer working on lavatory and kitchen sink drain assemblies will find this elbow useful for extending and redirecting drain runs at a 45-degree angle.

This coupling elbow is suited for residential under-sink drain assemblies, including lavatory and kitchen sink p-trap extensions. The included 1-1/2 inch by 1-1/4 inch reducing washer allows direct connection to fixtures with smaller drain tailpieces without an additional adapter. It is sold individually, one fitting per package.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer working under applicable IPC guidelines. Shut off the water supply and clear standing water from the drain before beginning work. Hand-tighten slip-joint nuts to avoid cracking the plastic body, then confirm alignment before final snugging. Verify there are no leaks at all connection points after restoring water flow.
