Comma Xstream Rad Seal

Radiator sealant is an essential maintenance chemical that is suitable for all seasons. Comma's Xstream Rad Seal version is a rapid sealer that instantly repairs leaks in radiators, cylinder blocks, heads and core plugs. After applying, leave it in the system of your car all year round to stop leaks as they occur.

To use, simply pour the contents of the bottle directly into the radiator/ cooling system. Run the engine for a few minutes until the Rad Seal hardens to stop leaks. Comes in a 500ml bottle.

Comma Oil and Chemicals was founded on a real 'passion for performance' in 1965 as a UK-based, independent oil 'blender'. Quickly establishing their products as being the first-choice supplier of engine oils to independent workshop mechanics in the UK, Comma has recently grown to distribute to more than 40 other countries around the world.

SHIPPING IS FREE* for orders of £60 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £4.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.

How long will it take to get my order?
