  • How can this product work in different types of systems?

  • How does Rislone One Seal Stop Leak work?

    After many years and kilometers, seals and gaskets tend to dry out and shrink. Rislone revitalizes these seals and makes them soft and pliable again.

  • How much Rislone One Seal Stop Leak do I install?

    Our 51334 (325mL) is designed for one bottle to treat one engine oil, transmission fluid or power steering fluid leak in a standard passenger car or light truck.

  • If first application does not completely stop leak, may I add another bottle?

    Yes, you can install a second application for hard to stop leaks. If your leak still persists after a second application, then mechanical attention may be required.

  • If I install more than the required amount, will it work faster or better?

    No, we have formulated our product to work best at the suggested dosage amount.

  • How long does it take to start working?

    Rislone One Seal Stop Leak starts working the minute you install and start driving the vehicle. You will usually see results in about 350 kilometers or three (3) days of driving.

  • Will Rislone One Seal Stop Leak clog my filter?

    No. Unlike our cooling system product, Rislone One Seal Stop Leak has no particles to plug the leak, it works chemically to stop leaks in gaskets and seals.
