Plumb Shop Div Brasscraft 823-674 Drain Extension Tube

Product Description

The PLUMB SHOP DIV BRASSCRAFT 823-674 is a white plastic lavatory drain extension tube designed to extend the drain line from a lavatory sink trap to the wall or floor drain connection. It features a 1-1/4-inch outer diameter slip joint end and measures 12 inches in length, making it a standard replacement for residential bathroom sink drain assemblies. The tube includes a slip joint nut and washer for a leak-resistant compression fit. Plumbers and drain service technicians use this tube when the existing drain extension is cracked, too short, or missing from a repair or remodel job.

This extension tube is suited for residential lavatory sink drain installations where the drain arm needs additional reach to connect to a P-trap or wall stub-out. Typical applications include bathroom vanities, pedestal sinks, and wall-hung lavatories. The white finish blends with standard white PVC drain components. The included slip joint nut and washer simplify assembly without additional fittings, making this a common part for rough-in corrections and drain realignment during sink replacements or bathroom remodels.

Key Features

• 1-1/4-inch OD slip joint connection for standard lavatory drain sizing
• 12-inch length provides reach for typical vanity-to-trap drain runs
• White plastic construction resists corrosion and moisture in wet drain environments
• Includes slip joint nut and washer — no additional fittings required for assembly

Compatibility

Designed as an OEM-style replacement for standard 1-1/4-inch slip joint lavatory drain systems in residential bathroom applications.

Installation Notes

Installation is typically performed by a licensed plumber or experienced drain technician. Shut off the water supply and clear standing water from the drain line before beginning work. Hand-tighten the slip joint nut first to align the tube, then snug with slip-joint pliers — avoid overtightening plastic fittings to prevent cracking. Verify all connections are leak-free by running water and inspecting joints after installation.
