Oatey 1774PC Tailpiece Extension Tube 1.25x18 in

Product Description

The OATEY 1774PC is a 17-gauge chrome-plated tailpiece extension tube designed for drain connections beneath sinks and lavatories. The tube bridges the gap between a sink strainer or P-trap and the drain outlet, providing a smooth, corrosion-resistant flow path. At 1.25 inches in diameter and 18 inches in length, this extension accommodates deeper cabinet installations where a standard-length tailpiece falls short. The chrome-plated finish delivers a clean, professional appearance and resists the moisture exposure typical in undercabinet plumbing environments.

This tailpiece extension is suited for residential and light commercial sink drain installations, including kitchen sinks, bathroom lavatories, and utility basins. It is typically used when the distance between the strainer outlet and the P-trap inlet exceeds the reach of a standard tailpiece. Licensed plumbers and experienced DIYers install this component during new sink installations or drain repair work.

Key Features

• 17-gauge wall thickness for rigid, durable construction
• Chrome-plated finish resists corrosion and provides a clean undercabinet appearance
• 1.25-inch diameter fits standard sink strainer and P-trap connections
• 18-inch length addresses deeper cabinet or extended drain runs
• Straight extension tube design simplifies installation in tight undercabinet spaces

Compatibility

Designed as an OEM-style replacement or upgrade tailpiece extension for standard 1.25-inch sink drain assemblies in residential and light commercial plumbing applications.

Installation Notes

Installation is typically performed by a licensed plumber or qualified tradesperson following local plumbing codes and IPC guidelines. Shut off the water supply and clear the drain line before beginning work. Slip-joint nuts and washers are commonly used to secure the tailpiece to the strainer outlet and P-trap — hand-tighten first, then snug with channel-lock pliers; do not overtighten, as over-torquing can crack fittings. Verify alignment of the drain assembly before final tightening to avoid stress on the trap arm connection.
