Oatey dear-pp9816 Branch Tailpiece 1-1/2 in Slip-joint Pp

Product Description

The OATEY dear-pp9816 is a branch tailpiece designed for residential drain plumbing applications. It connects a secondary drain inlet, such as a dishwasher or secondary basin, into the main drain line below the sink basket. Constructed from white polypropylene plastic, this tubular fitting accepts a 1-1/2 inch pipe and measures 8 inches in length. The slip-joint connection allows for tool-free hand-tightening with a slip nut and washer, making it straightforward to align and seat during rough-in or replacement work. Plumbers and experienced DIYers install this fitting as part of standard P-trap drain assemblies under kitchen and bathroom sinks.

This branch tailpiece is intended for use in residential kitchen and bathroom sink drain configurations where a branch inlet is needed to route an additional drain line into the stack. The 1-1/2 inch pipe size is standard for most residential sink drain applications. The polypropylene construction resists common drain chemicals and mild household cleaners. Domestic manufacture supports consistent dimensional tolerancing with standard tubular drain fittings.

Key Features

• Branch inlet design accepts a secondary drain connection below the sink strainer

• 8-inch length accommodates typical under-sink cabinet clearances
• Slip-joint connection allows hand-tightening and easy adjustment during installation

Compatibility

Designed as an OEM-style replacement for standard 1-1/2 inch residential slip-joint tubular drain assemblies under kitchen and bathroom sinks.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson in accordance with local plumbing codes and the IPC. Shut off the water supply and clear the area under the sink before beginning drain work. Hand-tighten slip-joint nuts to avoid cracking the polypropylene fittings — do not use pipe wrenches or channel-lock pliers with excessive force on tubular plastic components. Verify all slip-joint connections are leak-free before returning the drain to service.
