Plumb Shop Div Brasscraft 622-555 Drain Reducing Adapter

Product Description

The PLUMB SHOP DIV BRASSCRAFT 622-555 is a white plastic drain reducing adapter designed to connect 1-1/2 inch OD drain tubing to 1-1/4 inch OD drain tubing in residential sink and lavatory drain assemblies. Constructed from durable white plastic, this fitting provides a straightforward solution when transitioning between two common drain tube sizes under a sink. The kit includes a nut and washers, giving the installer everything needed to complete the connection. Plumbers and skilled DIYers handling under-sink drain repairs or reconfigurations will find this adapter a reliable, code-compatible fitting for standard P-trap and tailpiece assemblies.

This adapter is suited for residential bathroom and kitchen sink drain applications where the existing trap arm or drain tube does not match the diameter of the replacement or adjacent fitting. It is commonly used when connecting a 1-1/4 inch chrome or plastic tailpiece to a 1-1/2 inch trap or drain line, or when reconfiguring a drain assembly after a sink replacement. The included nut and washers simplify the installation and reduce the need for additional hardware.

Installation Notes

Installation is typically performed by a licensed plumber or experienced DIYer. Before beginning work, shut off water supply lines and clear standing water from the drain assembly. Hand-tighten the included nut and washer against the mating tube before applying final snug pressure to avoid cracking the plastic fitting. Check local plumbing codes, such as the IPC, for approved drain materials and assembly requirements in your jurisdiction.
