Rubber Washer

Material: rubber. Size: 1/2 inch nominal bore. Features: flexible, UV-resistant, temperature-variation tolerant, easy to install, provides an effective watertight seal and resistance to warping or misalignment.

Steps: 1) Shut off water and clean the mating surfaces. 2) Place the washer between the pipe joints or fittings. 3) Assemble the connection and hand-tighten, then snug the fitting—avoid over-tightening which can crush the washer.

Ideal for plumbing work: sealing pipe-to-pipe joints, taps, hose connectors, irrigation lines, and other 1/2 inch fittings where a watertight seal is needed.

This washer is made of rubber for standard plumbing use. It is not a food-contact material. Ensure compatibility with your system (e.g., potable water requirements) and avoid exposing it to chemicals that could degrade rubber.

Optional accessories include plumber’s tape (Teflon tape) for thread sealing and compatible fittings or nuts to ensure a secure joint. Keeping a small supply of washers on hand helps with quick repairs.

Potential issues include overtightening, which can crack the washer, misalignment causing leaks, or using incompatible materials. Ensure surfaces are clean, properly aligned, and use the correct size for the joint.
