Plumb Shop Div Brasscraft 453-258 Drain Extension Tube

Product Description

The PLUMB SHOP DIV BRASSCRAFT 453-258 is a white plastic drain extension tube designed to extend or adjust the length of lavatory and kitchen sink drain assemblies. It accepts 1-1/4 inch or 1-1/2 inch outside diameter slip joint connections, making it adaptable to the most common residential drain configurations. At 6 inches in length, it provides additional reach between the sink tailpiece and the trap or drain fitting below. The kit includes the extension tube, a slip joint nut, and washers required for a complete installation. Licensed plumbers and experienced DIYers install this component during drain rough-in, fixture replacement, or drain stack realignment work.

This extension tube is suited for residential lavatory and kitchen sink drain applications where the existing tailpiece falls short of the trap inlet. Typical scenarios include cabinet depth changes, fixture height adjustments after a countertop replacement, or corrections to an undersized original installation. Its dual-size compatibility with both 1-1/4 inch and 1-1/2 inch OD tubing reduces the need to stock multiple sizes on a service truck.

Key Features

• Fits 1-1/4 inch or 1-1/2 inch OD slip joint drain tubing
• 6-inch length adds reach between tailpiece and trap
• White plastic construction resists corrosion and chemical drain cleaners
• Includes slip joint nut and washers for a complete, ready-to-install kit
• Slip joint connection requires no solvent cement — hand-tool tightening only

Compatibility

Designed as an OEM-style replacement or extension component for standard residential lavatory and kitchen sink drain assemblies using 1-1/4 inch or 1-1/2 inch OD slip joint fittings.

Installation Notes

Installation is performed by a licensed plumber or qualified tradesperson following local plumbing codes and IPC guidelines. Shut off the water supply and clear standing water from the drain before beginning work. Hand-tighten the slip joint nut firmly against the washer — avoid over-tightening plastic slip joint nuts with pipe wrenches, as excess torque can crack the fitting. Inspect the washer seating and run water to confirm no leaks before closing the cabinet.
