Pasco 7421 Flanged Tailpiece 1.5x1.25x8 in 17 Gauge

Product Description

The PASCO 7421 is a flanged drain tailpiece designed for connecting sink drain assemblies to the trap or drain line below. Constructed to 17-gauge thickness, this tailpiece measures 1.5 inches inlet by 1.25 inches outlet by 8 inches in length, making it suited for standard lavatory and kitchen sink drain configurations. The flanged design seats securely against the basket strainer or drain body, providing a stable mechanical connection. Licensed plumbers and experienced drain installers work with this component during fixture rough-in, remodel drain work, and drain assembly replacements.

The PASCO 7421 is used in residential and light commercial drain applications where a reducing tailpiece is required to transition from a 1.5-inch drain outlet down to a 1.25-inch trap arm connection. The 8-inch length accommodates typical cabinet depths and allows for standard slip-joint or threaded trap connections beneath the sink. It is commonly specified during lavatory installations, sink replacements, and drain repair service calls.

Installation Notes

Installation is typically performed by a licensed plumber or qualified drain installer. Shut off the water supply and clear standing water from the drain line before beginning work. Use slip-joint pliers or channel-lock pliers when tightening slip-nut connections, and avoid over-tightening, which can crack nuts or distort the tailpiece. Work should conform to applicable local plumbing codes based on IPC or UPC standards as adopted in the jurisdiction.
