The PLUMB SHOP DIV BRASSCRAFT 622-548 is a white plastic drain tee designed for lavatory and kitchen sink drain assemblies. It accommodates 1-1/4 inch or 1-1/2 inch O.D. tube slip joint connections and features three ends for straightforward branch drain configurations. Nuts and washers are included, making this a complete slip-joint fitting ready for installation without additional hardware. Plumbers and experienced DIYers use this fitting to connect a branch drain line into a main drain run beneath a sink basin in both residential and light-commercial settings.
This drain tee is suited for use in lavatory and kitchen drain systems where a slip-joint tee connection is required. Its dual-size compatibility with both 1-1/4 inch and 1-1/2 inch O.D. tubing makes it a versatile fitting for common drain configurations found under bathroom vanities and kitchen sinks. The white plastic construction resists corrosion and is compatible with standard P-trap and tailpiece drain assemblies typical in residential plumbing.
Designed as an OEM-style replacement and standard-fit slip-joint drain tee for residential lavatory and kitchen sink drain assemblies using 1-1/4 inch or 1-1/2 inch O.D. drain tubing.
Installation is typically performed by a licensed plumber or qualified DIYer familiar with drain, waste, and vent plumbing. Turn off the water supply and place a bucket under the drain before beginning disassembly of existing drain components. Hand-tighten slip-joint nuts to seat the washers, then snug with channel-lock pliers — avoid overtightening plastic fittings as this can crack the nut or tee body. Verify alignment and check for leaks by running water through the drain after assembly.
