Plumb Shop Div Brasscraft 829-645 Lavatory Drain Coupling

Product Description

The PLUMB SHOP DIV BRASSCRAFT 829-645 is a chrome plated brass lavatory drain coupling designed for slip joint connections on both ends. It accepts 1-1/4 inch OD tubing and provides a watertight connection between lavatory drain components in residential bathroom sink installations. The coupling ships with nuts and washers included, giving the installer everything needed to make both slip joint connections without sourcing additional hardware. Chrome plated brass construction delivers corrosion resistance appropriate for wet drain environments while maintaining a finished appearance where the fitting is visible under the sink.

This coupling is used in residential lavatory drain assemblies, typically connecting the tailpiece, P-trap, or extension tube beneath a bathroom sink. It is suited for standard 1-1/4 inch OD drain tube systems commonly found in residential vanity and pedestal sink installations. Licensed plumbers and experienced DIYers install this fitting during new lavatory rough-ins, drain reconfigurations, and P-trap replacements. The carded retail packaging makes it practical for both shop inventory and point-of-sale stocking.

Installation Notes

Installation is performed by a licensed plumber or qualified DIYer. Shut off the water supply and clear standing water from the drain line before disassembling existing trap components. Hand-tighten slip joint nuts to avoid cracking the nut or deforming the washer; use slip-joint pliers only if needed to achieve a snug, leak-free fit. After installation, run water and inspect both joints for leaks before closing out the service call.
