Bleed Valves & Blanking Plugs
Bleed valves and blanking plugs are essential radiator fittings that keep your heating system running efficiently. A bleed valve releases trapped air to restore full heat output, while a blanking plug safely seals unused tappings. Together, they help prevent cold spots, leaks and performance issues.
Choosing durable radiator bleed valves and blanking plugs ensures reliable sealing and smooth system operation. High‑quality components reduce heat loss, improve radiator efficiency and minimise maintenance. They’re a simple, cost-effective upgrade that supports long‑term heating performance.
Explore our range of universal bleed valves, chrome blanking plugs and specialist radiator fittings designed for modern and traditional systems. All products offer easy installation, reliable sealing and compatibility with a wide variety of radiators.

Nice finishing touches
29th April 2026I bought these vents to go with my new Keswick radiator. They look nice, though I haven't really used them yet, so can't vouch for how easily they bleed the radiator. My plumber fitted them and didn't have any negative comments.

Not sure why these are an optional extra.
16th March 2026I bought these to use on the Keswick black radiator. It baffles me as to why the radiator isn't supplied with black caps rather than chrome. Surely they should be sold together as a complete item.
