Boiler O-Rings & Washers

Over time, small parts including rubber seals, O-rings and washers in a home heating system can deteriorate and need replacing.
Seals and washers prevent internal leaks, so ensuring they are working effectively and placed correctly is essential. They’re needed in many different points within a boiler to join parts like heat exchangers to the pipework of a central heating system. 
Sourcing new parts can be a long and frustrating process, but it’s easy to find them here at City Plumbing, both online and across our UK branches. We stock an extensive range of boiler O-rings, washers, gaskets and seals to ensure the system you're working on is operating efficiently.
We know that when a boiler breaks down, you’ll need new parts as soon as possible. That’s why we offer no-fuss next-day delivery on our products in addition to our click & collect service, which is ideal for customers near one of our branches.

Which boiler O-rings & washers are available?

We’ve partnered with trusted suppliers to bring you parts from Alpha Boilers, Glow-worm, Worcester Bosch and many more leading brands. Boiler washers and seals come in various shapes and sizes, so you’ll need to choose the right replacement for your specific task.

Our range includes boiler O-rings in various kit sizes from Worcester Bosch and Glow-worm, as well as washer and gasket sets from Ideal and Grant
