Oatey 1901PC Chrome Slip Joint Extension Tube

Product Description

The OATEY 1901PC is a chrome slip joint extension tube designed for drain line connections beneath sinks and lavatories. Measuring 1.25 inches in diameter and 6 inches in length, this extension tube bridges the gap between P-traps, tailpieces, and drain assemblies when standard components fall short. The chrome plated finish provides a clean appearance in exposed under-sink installations. Licensed plumbers and experienced DIYers install this type of fitting as part of drain waste and vent rough-in or finish trim work on residential and light commercial fixtures.

This extension tube is suited for residential bathroom and kitchen sink drain applications where additional reach is needed to complete a slip joint drain assembly. It is commonly used alongside P-traps, trap arms, and tailpieces in standard 1.25-inch slip joint drain configurations. The slip joint design allows for tool-free length adjustment during fitting and alignment before final tightening.

Key Features

• 1.25-inch diameter slip joint connection for compatibility with standard drain assemblies
• 6-inch length provides extension reach for misaligned or deeper drain configurations
• Chrome plated finish suits exposed under-sink installations
• Slip joint ends allow positional adjustment during installation

Compatibility

Designed as an OEM-style replacement and retrofit extension tube for standard 1.25-inch slip joint residential sink and lavatory drain assemblies.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer working on sink drain assemblies. Shut off the water supply and clear standing water from the trap before disassembling drain components. Hand-tighten slip joint nuts first to confirm alignment, then apply a final snug tighten with slip joint pliers — do not overtighten, as this can crack slip joint nuts or distort washers. Work must comply with applicable local plumbing codes and the International Plumbing Code where adopted.
