Oatey dear-pp9818 Branch Tailpiece 1-1/2 in Slip-joint Pp

Product Description

The OATEY dear-pp9818 is a tubular branch tailpiece designed for drain line assemblies under sinks and lavatories. It accepts a 1-1/2 inch slip-joint connection and measures 8 inches in length, making it a standard fit for typical residential trap-to-drain configurations. Constructed from polypropylene plastic, the fitting resists corrosion and common drain chemicals. The white finish suits standard vanity and kitchen sink installations. Licensed plumbers and experienced DIYers install this fitting as part of P-trap or double-bowl sink drain assemblies.

This branch tailpiece is used in residential drain, waste, and vent (DWV) applications beneath kitchen sinks, bathroom lavatories, and utility sinks. It connects the sink basket strainer or drain outlet to the P-trap, and the branch outlet accommodates a secondary drain connection such as a dishwasher drain or secondary bowl. The slip-joint design allows for tool-free hand-tightening with a slip-joint nut and washer, simplifying alignment during rough-in and final trim.

Installation Notes

Installation is performed by a licensed plumber or qualified trades person following local plumbing code requirements, including applicable IPC standards. Shut off the water supply and clear standing water from the drain before disassembly. Hand-tighten slip-joint nuts to avoid cracking the polypropylene fittings — do not over-torque with channel-lock pliers. Inspect the slip-joint washer for wear and replace if compressed or cracked before reassembling the drain stack.
