Radiator Caps

Radiator caps seal the radiator opening so air cannot enter the system, helping it run efficiently and reducing cold spots. If your current cap is worn and letting air in, replacing it with a proper cap set will restore correct pressure and improve heating performance. Many of the included in our range options are aluminium cover cap sets in chrome, so you get both the sealing function and a neat visual finish.

Match the cap set length to the length or model of your radiator, the range includes specific sizes such as 292mm, 440mm, 810mm, 1032mm and up to 1254mm. Also match the type number (Solaro Type 10 or Type 20) to your radiator profile; a Solaro Type 20 810mm chrome cap set is the right choice for an 810mm Type 20 radiator. If you have a non-standard length, pick the closest larger included in our range size and check compatibility with the radiator profile.

Type 10 cap sets are designed for single-panel, single-convector radiators, while Type 20 suits double-panel, double-convector radiators that have greater depth. Use a Type 10 aluminium cap set on slim single-panel radiators; choose a Solaro Type 20 cap set when you have a deeper, double-panel unit to ensure the cap aligns with the radiator profile.

The range is primarily aluminium with a chrome finish, which gives a polished look, is lightweight and resists corrosion, good for bathrooms and kitchens where moisture is present. Patterned aluminium options are also available if you want a decorative touch rather than a smooth chrome face; a patterned 470mm chrome cap set adds visual interest to a traditional bathroom while still sealing the radiator.

A cover cap set is both functional and decorative, it seals the radiator to keep air out and tidies the ends so your radiator matches a cover or the room styling. fitting a Solaro Chrome cap set before installing a wooden radiator cover gives a neat, continuous look and prevents dust ingress at the exposed ends. Because the caps are aluminium, they won't add significant weight or interfere with the cover's fit.
