Oatey PP169 1-1/4 Inch Chrome Slip Coupling

Product Description

The OATEY PP169 is a double-slip straight coupling designed for 1-1/4 inch drain line connections in sink and lavatory drain assemblies. Constructed from 22-gauge chrome-plated brass, this coupling includes the necessary nuts and washers for a complete compression-style connection. The double-slip design allows both ends to slide and adjust during alignment, making it easier to fit between fixed drain components without cutting or threading pipe. It is a standard repair and replacement part installed by licensed plumbers and experienced pipe fitters working on residential and light commercial drain, waste, and vent systems.

This coupling is suited for use in exposed drain applications under sinks where a finished chrome appearance is required. Typical installations include P-trap connections, tailpiece extensions, and drain line repairs on lavatory or kitchen sink assemblies. The included nuts and washers eliminate the need for sourcing additional hardware. Each unit is sold individually per card, making it appropriate for single-fixture service calls and small repair jobs.

Key Features

• Double-slip straight design allows independent adjustment on both ends for easier alignment

Compatibility

Designed as an OEM-style replacement and repair coupling for standard 1-1/4 inch residential and light commercial sink drain assemblies.

Installation Notes

Installation is typically performed by a licensed plumber or qualified pipefitter. Shut off the water supply and clear standing water from the drain line before beginning work. Hand-tighten coupling nuts first to confirm alignment, then snug with channel-lock pliers - avoid over-tightening, which can crack the slip washers. Work must comply with applicable local plumbing codes referencing the IPC or UPC as adopted.
