Ultraseal is a special blend of more than 24 chemicals in a viscous liquid state which coats and clings to the inner wall of the tyre.

Ultraseal is a permanent puncture preventative/repairer and tyre life extender/conditioner, and we believe the only product on the market today that is guaranteed to last the legal life of the tyre.




Ultraseal was initially developed for Military combat vehicles, armoured vehicles and off road equipment. Used in combat vehicle tyres where bullet wounds would prevent any vehicle from completing its mission, Ultraseal is capable of sealing large wounds, thereby allowing vehicles to maintain mobility.

Once again, Ultraseal provides that extra reliability and very important uptime on mining and construction equipment, where downtime is extremely costly. XHD grade is not designed for regular passenger vehicles. It will seal wounds caused by puncturing objects up to 12mm in diameter


This grade is formulated for any vehicle with pneumatic tyres, tube or tubeless, high or low air pressure used on highway speed vehicles or slow off road equipment tyres. This formula will seal wounds caused by puncturing objects up to 6mm in diameter.




Sealants have caused many problems that we at Ultraseal have addressed.

Using a highly evolved mixture of chemicals, we have devised a product that is more than capable of working in harmony with today’s modern breed of vehicles. We have included a patented thixotropic emulsion (Thixogel™) that bonds the molecules of the product together at speeds up to 240km/h, thus allowing the driving complete flexibility. Previously available products (and most current ones) have simply fallen apart at speeds of 65 km/h and over, because they were manufactured for the construction industries slow vehicles, but eventually made their way into the high-speed markets creating problems, whereas Ultraseal contains only tiny strands of coarse surface synthetic fibers that are stronger than steel when they interlock tightly together, but will only positively repair small holes caused by puncturing objects up to 6mm in diameter, but only in a hole that is in the tread area of the tyre, and that is shrinking in size because there is no cord damage (rubber recovery), which is 95% of today’s high speed punctures.

Anything bigger, or in the sidewall, with or without cord damage, and the Ultraseal fibers just slowly bleed through the hole, giving a controlled deflation, and usually with a halt or abrupt slow down in air pressure loss at the lower pressures of 10 to 15 psi (depending on cord damage) which prevents damaged rims, and helps the driver maintain control and possibly enabling continuation of the journey to remove the vehicle from a possibly dangerous location.

Ultraseal is not a get you home product, it is applied before the puncture occurs, and permanently repairs puncture after puncture in the same tyre over and over.

Once installed, Ultraseal not only repairs punctures, it conditions the inner casing, preventing porosity leaks caused by tiny holes and cracks. In other words after installing Ultraseal the tyres maintain correct air pressure and the need to regularly top up with air is virtually eliminated, and with correctly inflated tyres you get better fuel economy, your tyres also run cooler eliminating that killer problem of devastating heat build-up. Tyres treated with Ultraseal last up to 40% longer, and unlike temporary sticky oil based sealants, Ultraseal is water based for easy clean out if ever you need to do this.

Ultraseal converts any pneumatic tyre into a self-sealing tyre that will maintain air pressure.

Ultraseal has the unique ability to coat the entire inner surface of a tyre and rim without succumbing to shear and stress associated with centrifugal force that is created within a high speed rotating tyre. Ultraseal’s attributes are unparalleled in the history of the pneumatic tyre.
