Heavy Duty – On Road

This grade of sealant will provide a high level of tyre protection for a wide range of on-road vehicles with multi-axle construction. This protection is important for large transporters used for suppliers to supermarkets, major industrial product manufacturers, the motor industry, buses, coaches, minibuses and other markets where delivery on time is an essential requirement. For Fleet Managers using a wide range of vehicle types and designs for every form of product distribution, the reduction in downtime while waiting for the tyre to be replaced would have significant cost savings.

On Road Benefits:

  • Increases tyre life by up to 20%
  • Reduces fuel costs by maintaining correct tyre pressures
  • Avoids downtime waiting for tyre repair or replacements
  • Prevents costly penalties for late deliveries

Under inflation or slow air leaks are the leading causes of premature tyre wear. By installing our sealant it will extend the life of the tyre and increase fuel economy by reducing tyre drag.

This product also seals up to 95% of punctures while dissipating heat within the tyre which increases tread life by up to 20%. Once a puncture occurs, the centrifugal force and the jet action of escaping air propel the sealant to the area of the problem. As the tyre flexes under load conditions, the multi-sized fibres and fillers are compressed to form a permanent plug. Air loss is minimal. This process can be repeated many times without the need of additional sealant. One application of sealant will save you money when compared to a conventional repair. It also avoids the inconvenience, time and effort involved in replacing a tyre.

An Installation Manual is supplied with an application chart which details the amount of tyre sealant necessary for any combination of tyre sizes.

Heavy Duty is supplied in 20 litre pails and is sold with a specially engineered installation pump for ease of use. Intermediate Bulk Containers (IBCs) are also available.

We have supplied our Heavy Duty product to The Royal Mail Group since 2010. It is installed throughout the fleet of 52,000 vans nationwide. In 2016 we were listed as a continuous sole supplier.
