How Monster Seal Works
A Detailed Description


MONSTER SEAL is the world’s most advanced premium in-tire sealant designed as a preventative maintenance system to prevent and to repair flat tires due to tread-area punctures and other leaks.  Our tire sealant formulas have been tested, proven and trusted for over 40 years, and continue to be the most advanced in the world.  

MONSTER SEAL provides continuous protection for the life of the tire.  MONSTER SEAL quickly seals existing punctures, along with small bead and rim leaks.  MONSTER SEAL remains fluid inside the tire, instantly and permanently sealing numerous tread-area punctures as they occur. 

MONSTER SEAL will increase tire service life, while reducing downtime costs on both high and low tire pressure tires.  MONSTER SEAL is effective for on and off-road vehicles using tubeless and tube-type tires, traveling at high and low speeds.  MONSTER SEAL also works great for autos, trucks, trailers, RV's, SUV’s, ATV's, motorcycles, bicycles, lawn and garden equipment, riding mowers, utility & golf carts, wheelbarrows, tractors and more! 

MONSTER SEAL will seal the tire to help maintain correct tire air pressure.  It’s designed to repair and prevent flats from tread area punctures of 1/4" inch in diameter in tubeless tires (and often seals larger punctures in heavier ply commercial tires), and 1/8" inch punctures in tube-type tires. This tire sealing ability makes greater dollar savings possible from:

A. Increased tread service life.

B. Lower tire maintenance and repair costs.

C. Lower downtime costs.

D. Improved fuel economy.

Improved fuel economy and increased tire life, plus fewer hours of expensive downtime and tire maintenance, provides significant savings.


MONSTER SEAL is a revolutionary product made using an ethylene glycol based and water soluble solution, containing inert fibers and sealing solids in permanent suspension.  This solution is carefully blended with adhesion agents and anti-corrosion inhibitors, to produce the worlds most advanced premium tire sealant formula.  These selected ingredients remain in permanent suspension -- there is no settling out, so no special mixing or preparation is required.  Monster Seal does not separate in the bottle or the tire.

Since there is virtually no evaporation inside an inflated tire chamber, MONSTER SEAL remains fluid to perform for the life of the tire.  It remains in liquid and in permanent suspension throughout the life of the tire.  The adhesion agent in MONSTER SEAL holds it in place, even after the tire has stopped operation, to provide continuous protection against air loss.  MONSTER SEAL is completely water-soluble for easy clean up of hands, clothes, and even the tire if retreading is desired.  MONSTER SEAL is non-flammable, non-combustible and biodegradable and non-hazardous.


MONSTER SEAL is injected into the tire through the valve stem (see installation directions).  The motion of the rotating tire causes MONSTER SEAL to spread in all directions.  The entire surface areas of the tire cavity are coated.  When such spreading occurs, MONSTER SEAL is placed into position to function for the life of the tire.  The adhesion agent in MONSTER SEAL holds it in place even after the vehicle has stopped.  MONSTER SEAL instantly seals causes of air loss, whether it is from punctures in the tread area, small rim and bead leaks, or the inevitable porosity of natural rubber. 

MONSTER SEAL will not cause tire imbalance when the correct amount of sealant is properly installed. Monster Seal will not rust or corrode wheels, or harm tire components.  Monster Seal will not void the tire manufacturers workmanship warranty.  By maintaining correct air pressure and the resultant cooling of the tire, MONSTER SEAL can extend tire life by up to 25% or more.  MONSTER SEAL is water-soluble for easy wash out of the tire, which allows the tire to be patched, plugged and retreaded, if desired.

After the tire is punctured the MONSTER SEAL starts to enter the hole.  This instantly forms a temporary seal to help stop the air loss.  As the tire continues to rotate under load and the tread area is allowed to flex, the solution is squeezed into and out of the puncture as it rolls off of he load point, leaving the fiber, sealing solids and adhesion agent in the hole.  Repeated rolling under load deposits more of these components until a permanent seal is formed.  This process is repeated when the puncturing object is removed.  The tire must roll under load, after the puncture, allowing the tread area to flex, forcing the sealant into the wound to insure proper sealing.  Under actual operating conditions, this entire sealing process may be almost instantaneous. 

MONSTER SEAL is designed to seal punctures in the tread area up to 1/4 inch in diameter in tubeless tires (often times capable of sealing larger punctures in heavy ply industrial tires) and 1/8" inch in tube-type tires. It can often seal larger punctures in heavy-duty tires on industrial equipment.


Installation is safe, quick and simple with our calibrated hand injection pump.  The pump fits into the top of the pail and injects 10 ounces per full stroke.  The injection pump is very durable and can easily overcome up to 50 lb. of tire pressure – there is no need to completely deflate the tire, so installation time is kept to a minimum.  MONSTER SEAL comes ready to install, no mixing or special preparation is needed.  Instructions and a tire application chart are provided on the pail label and with each hand injection pump kit.  The pump is completely reusable and may be cleaned for storage by flushing with water, although we suggest leaving the pump in the pail for convenience.  (A high-pressure pneumatic injection system is available for high volume MONSTER SEAL customers with large fleets.)


Installation is safe, quick and simple from the retail bottle.  The installation kit (valve core tool and filling hose) is securely stored under the bottle cap.  To install Monster Seal, simply remove the valve core and deflate the tire.  Place one end of the filling tube over the nozzle on the bottle cap, then place the other end of the hose over the tire valve stem.  Using the measurement guide printed on the side of the bottle, squeeze the required amount of Monster Seal into the tire.  Replace the valve core and inflate the tire to the proper tire air pressure.  If the tire is already punctured, remove the puncturing object and immediately rotate the tire, so the sealant can spread to reach the puncture.

When installing Monster Seal into high-speed tires, the tires should be properly balanced before installation.  Installation should be done near an air compressor so the tires can be easily re-inflated.  Monster seal is more effective in tubeless tires, and also provides superior protection from flats in tube-type tires.


MONSTER SEAL has a cooling effect on the tire.  MONSTER SEAL reduces the tire operating temperature through both correct inflation pressure maintenance and the thermal conduction affect.  Because of the variation of the internal and external friction on various parts of the tire, and since rubber is a very poor conductor of heat there are substantial differences in temperature at various points within the tire.  The ethylene glycol content of MONSTER SEAL acts as a thermal conductor, transferring heat from areas of higher temperature to areas of lower temperature.  This thermal distribution of heat helps to keep the overall tire temperature down during operation.  The effect of thermal conduction tends to be greater in larger, slower moving industrial and commercial tires, because of the larger areas of the side wall that are coated with MONSTER SEAL. The cooling effect that MONSTER SEAL has on the tire, results in a longer tire life.


Heat generated from under-inflated tires frequently contributes to retread separations.  Tubeless retreads may be particularly vulnerable to tread separations.  Small holes in the inner liner may be missed in the pre-retread inspection. High-pressure air passes through these small holes to the new rubber of the tread.  With its escape route cut off, air spreads out between the old casing and the new tread until separation and failure occurs.  By effectively and immediately sealing these small liner holes, MONSTER SEAL reduces the pressure on the new tread.  As a result of using MONSTER SEAL, the integrity of the tire casing is maintained and the full service life of the tire and casing is maximized.  MONSTER SEAL is completely water-soluble and fully compatible with all methods and compositions used in the tire retreading process. 

MONSTER SEAL increases tire life and fuel economy.

Air loss can come from: 

1. Tread area punctures.

2. Small rim and bead leakage.

3. The natural porosity leaks of rubber tire and tube. 

One of the most frequent causes of tire failure is under-inflation.  Under-inflated tires increase fuel usage, run hotter, wear faster, and are much more subject to punctures and other road hazard damage.  Hot rubber simply wears faster and has less resistance to cuts and punctures.  According to the American Trucking Association, a truck tire under-inflated by just 6 lb. PSI can destroy over 10% of the overall life of the tire! 

Under-inflation can become extremely costly for a fleet.  Fuel economy suffers when tires are under-inflated.  Studies show that under-inflation increases rolling resistance, which means more fuel is consumed in moving the tires and vehicle.  The difference can mean a 12% or more increase in fuel economy.  Rubber tires are relatively porous; most tires will lose air over time, some faster than others. Upon installation, after a few miles of operation, MONSTER SEAL will virtually eliminate the slow rubber porosity air loss and small rim and bead leaks to help maintain the proper tire air pressure for the life of the tire.
