Oatey 20-12WK 1.5x12 in White Plastic Extension Tube

Product Description

The OATEY 20-12WK is a white polypropylene extension tube designed to lengthen the waste connection between a sink tailpiece and a drain or trap assembly. Measuring 1.5 inches in diameter and 12 inches in length, this tube is used where the existing drain outlet does not reach the trap inlet. Connection to pipe requires solvent welding. Nuts and washers are included to complete the joint and help maintain a leak-free seal. At 0.25 pounds, the tube is lightweight and straightforward to handle during installation.

This extension tube is suited for residential under-sink drain assemblies, typically found in kitchen and bathroom installations where the drain rough-in is positioned lower than the sink outlet. Plumbers and plumbing contractors install this type of fitting during new construction, remodel work, or when replacing deteriorated tubular drainage components. It is sold individually and is appropriate wherever a standard 1.5-inch tubular drain extension is needed.

Key Features

• 1.5-inch diameter fits standard residential sink drain and trap assemblies
• 12-inch length extends waste connection to reach drain inlet
• White polypropylene construction resists corrosion and moisture
• Solvent-weld connection method for a secure, permanent joint
• Nuts and washers included for a complete installation

Compatibility

Designed as an OEM-style replacement or new-installation component for standard 1.5-inch residential tubular sink drain systems.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson. Shut off the water supply and ensure the drain system is empty before beginning work. Solvent welding requires a compatible PVC or ABS cement applied per the cement manufacturer's instructions and local plumbing code, typically referencing IPC or UPC standards. Do not over-tighten mechanical nuts, as polypropylene threads can crack under excessive torque.
