Description

Cronex Rubber Sink Washer 1‑1/4″ is a sealing washer designed for use in plumbing applications, specifically to create a watertight seal in sink drains and waste fittings measuring 1‑1/4″. It fits between pipe connections—such as in slip‑joint drain assemblies—to prevent leaks and ensure a secure, flexible connection between components. Rubber washers like this are essential in sinks, basins, and waste traps because the material compresses to fill gaps and maintain a reliable seal under water pressure. Cronex’s range of rubber washers is manufactured from high‑quality durable rubber to withstand everyday use and resist deterioration over time.
