Steel Seal Guarantee

At Steel Seal our highest priority is to repair your head gasket and keep it repaired, to get you permanently back on the road.

For this reason, if Steel Seal is used on a blown head gasket and has not worked, we are more than happy to provide a full refund of receipt value to a maximum of the RRP as displayed on our website or a one-time replacement bottle.

You can receive a full refund up to 30 days after purchase. After 30 days, if the repair to a blown head gasket fails at any point during the time you own your vehicle, we will send you additional product at no extra cost.

All you need to do is simply provide us with:

  • Proof of purchase for Steel Seal from an authorised stockist as listed on our website
  • A statement from a VAT registered garage that via compression or gas test that your vehicle definitely has a blown head gasket or confirmation that the vehicle has been scrapped or an invoice showing that a mechanical head gasket repair has subsequently been carried out
  • The registration number of vehicle


  • Only 1 refund per vehicle
  • The recommended amount of Steel Seal must have been used up to a maximum of 3 bottles.
  • Steel Seal now comes with a lifetime money back guarantee, so if at any point Steel Seal fails you can claim your money back.

You can send your completed claims form back to us either by post or via email.
