Plumb Shop Div Brasscraft 823-666 Drain Extension Tube

Product Description

The PLUMB SHOP DIV BRASSCRAFT 823-666 is a white plastic lavatory drain extension tube designed to extend or replace drain tailpiece assemblies in bathroom sink installations. Sized at 1-1/4 inch outer diameter with an 8-inch length and a slip joint connection, this tube bridges the gap between the sink drain outlet and the P-trap below. It ships with a nut and washer included, making it a complete drop-in solution. The plastic construction resists corrosion and is well suited for typical residential lavatory drain applications. Licensed plumbers and experienced DIYers both install this type of fitting as part of routine drain servicing or sink replacement work.

This extension tube is used in residential bathroom sink drain systems where additional length is needed between the sink strainer outlet and the P-trap inlet. The slip joint design allows for tool-free adjustment and a secure, leak-resistant connection when the nut is hand-tightened and snugged. It is commonly installed during lavatory sink replacements, drain repositioning, or when an existing extension tube is cracked or damaged. The included nut and washer eliminate the need to source additional hardware.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer. Shut off water supply and clear standing water from the drain before beginning work. Hand-tighten the slip joint nut to seat the washer, then snug with channel-lock pliers — do not overtighten plastic fittings. Follow local plumbing codes, which generally reference IPC standards for residential drain assembly.
