 Installation Instructions 


Commercial on road use:  Tire Height X Tire Width ➗ 10 = ounces per tire

Commercial off road high flat rate use: Tire Height X Tire Width ➗ 5 = OZ per tire

Passenger vehicle use: Tire Height X Tire Width ➗ 27 = ounces per tire

Most passenger vehicles will use either: 8, 10 or 12 ounces per tire depending on size.

Off Road Race tire use: Tire Height X Tire Width ➗ 10 = ounces per tire. 

Scroll down for information regarding Off-Road race tires. 

The 5-Gal. Pump Kit includes detailed instructions and a tire ounce chart. 

Example ounces per tire for passenger light truck tires traveling on the highway:

- 35 X 12.5 / 18 = 18 ounces per tire

- 37 X 12.5 / 18 = 18 ounces per tire

- 350/70 R18 = 18 ounces per tire

- 285/70 R17 = 14 ounces per tire

Example ounces per tire for RV tires:

- Class A / Super C - 40 ounces per tire

The following are the recommended ounces to use for OFF ROAD RACE TIRES:

(UTV Tires: 30-32oz)   (33" Tires: 40oz)   (37" Tires:  50oz)   (39-40" Tires:  60oz) 

Or, use formula: Tire Height X Full Tire Width (Sidewall to Sidewall) 10 = OZ Per Tire. 

Most race teams use the 5-gallon (640 ounce) pails with our reusable hand pump kit. The hand pump allows for the quick installation through the valve stem without deflating the tire. The 5-gallon pump overcomes up to 40 psi tire pressure. Monster Seal can be injected into a race tire in about 1-2 minutes.



MONSTER SEAL is easy to install through the tire valve stem from a small squeeze bottle, a one gallon jug with a small one ounce hand pump, or from a five gallon container using our hand injection pump kit. Our 5-gallon hand pump will overcome up to 40 psi tire pressure, so you don't need to fully deflate your tires to install Monster Seal from a 5-Gallon container.  

The hand pump is adjustable and will inject up to ten (10) ounces per full pump stroke.  All of our containers include a valve core removal tool, easy to follow instructions and tire size charts on the labels. The 5-gallon hand pump kit includes a valve core removal tool, detailed tire size / ounce per tire chart, and installation instructions. It only takes a few minutes to install Monster Seal into most tires with the hand pump from a five gallon pail. 


- Position the tire valve core between 1-5 or 7-11 o'clock 

1. Remove the valve core from the valve stem. (Valve core tool included with pump kit)

2. Deflate the tire to under 40 psi - (leave some air pressure in the tire)

3. Attach the quick connect hose fitting onto the valve stem. 

4. Pump the sealant into the tire (pump injects up to 10 ounces per stroke)

(If pump clogs - do not force it. Back the connector off the stem and allow pressure in the tire to free the clog, or use a firm piece of wire to clear the clog and continue pumping. 

5. Insert the valve core back into the valve stem

6. Inflate the tire to the correct pressure listed on the sidewall of the tire.

7. When the vehicle is driven, the sealant will coat the inside of the tire.

8. If tire contains puncturing object, remove it and drive at least 1/4 mile to make a seal


- Position the tire valve core between 1-5 or 7-11 o'clock 

- Valve core tool and filling hose under bottle cap. 

- Snip off end of the pointed nozzle on the cap and attach hose to end of nozzle.

1. Remove the tire valve core and fully deflate the tire - remove all air pressure

2. Place the hose over the valve stem.

3. Squeeze the bottle to inject the recommended ounces of sealant into the tire

4. Install the valve core back into the valve stem

5. Inflate the tire to proper air pressure note on the side of the tire

6. If tire contains puncturing object, remove it and drive at least 1/4 mile to make a seal

7. If tire delates, re-inflate and drive further to make a seal.

Monster Seal is designed to seal tread area punctures and small rim and bead leaks.


We have manufactured a special "Monster Seal Pneumatic Injection Pump and Air Hose and Inflator System" which quickly installs Monster Seal without deflating the tire.  Our patent pending installation tool connects to the valve stem and quickly removes the valve core back into a connected chamber.  After the sealant is installed, the valve core is screwed back into the valve stem. The attached air hose and inflator is used to ensure the tire has the correct air pressure. 

The pneumatic pump works with your air compressor/source and reduces the installation time by up to 75% or more. The pump system can be used with a five gallon pail or a 55 gallon drum. Our pneumatic injection system includes a 25 foot combined sealant and air hoses, and a tire gauge and an inflator.  It only takes about two minutes to install 46 ounces into a large truck, Class A, and class Super C RV tire. It takes less than two minutes to install the sealant into a RV trailer tire


- Set the pump air pressure meter on pump to 100 to 120 psi

1. Attach the special Monster Seal installation tool to the tire valve stem.

2. Use the special tool to unscrew the valve core.  Leave the air pressure in the tire.

3. Inject the Monster Seal into the tire. The pump includes an ounce meter. 

4. Clear the valve with shot of air with the attached inflator hose.

5. Screw the valve core back into the valve stem.

6. Set the correct tire air pressure using the attached inflator/tire gauge. 

7. Remove the special Monster Seal tool from the tire valve stem.

8. Attach the special tool to the valve stem vent on the side of the 5-gallon pail.
