How does MULTI SEAL® Tire Sealant work?

MULTI SEAL Tire Sealant is a high-tech system of fibers and "fillers" in a carefully designed liquid suspension.  When you install MULTI SEAL® into your tire it will be protected 24/7. When a puncture occurs, the escaping air pushes MULTI SEAL® Tire Sealant into the hole.  Together, the fibers and fillers form a plug, which seals the leak with almost no air loss.  As the tire flexes under load, the fiber/filler mass compresses to form a dense plug.  The process will repeat itself for each additional puncture.

  • Manufactured for tough environments to protect your tires from punctures and slow leaks.  
  • Seals up to 3/4 inch punctures.
  • 95% effective in tread punctures.
  • Contains synthetic fibers including DuPont KEVLAR fibers and other special components that are suspended in an environmentally friendly solution of propylene glycol and other components.
  • When a puncture occurs, these fibers and other components are forced into the puncture site, which instantly and permanently seals the puncture site.  It's like plugging the tire from the inside out.  
  • Never dries out.  One treatment good for the life of the tire.
  • Made with DuPont KEVLAR fibers and other synthetic fibers.
  • Not flammable.  
  • Won't freeze (-30F to +250F)

MULTI SEAL® Industrial Tire Sealants have helped companies save millions of dollars in tire repairs/replacements, damage to wheels and equipment, fuel costs, insurance costs, service calls and employee/equipment downtime.  

MULTI SEAL® Tire Sealant prevents flats up to 95% of the time due to punctures in the tread area, plus fixes slow leaks. Tires normally lose air pressure over time, but MULTI SEAL® Tire Sealant seals all the areas where air loss normally occurs, including the valve stem, through the tire's natural porosity and along the bead. MULTI SEAL® Tire Sealant prevents most blowouts, prolongs tire life and improves fuel economy. 

MULTI SEAL® formulas are all environmentally friendly and water washable, the tire professional will not have any difficulty removing MULTI SEAL® from the tire if you ever need to have a tire repairIn the event that the tire needs to be repaired, the tire is repairable and re-treadable.

MULTI SEAL® Tire Sealant is not the same as other sealants. MULTI SEAL® is a glycol based product which uses synthetic fibers including KEVLAR® and other unique components. The lack of adhesive agents means MULTI SEAL® will not dry up.  

When a puncture occurs the components are pushed into the puncture site by the tire's air pressure which instantly and permanently seals the puncture. The repair is generally complete within about three revolutions of the tire. The product is completely water washable. It will not corrode the tire or the rim. When the tire is moving, the rotating action of the tire moves the product evenly throughout the tire.


If you work, or live in rugged environments where your tires are constantly exposed to jagged rocks, nails, screws, mesquite and other hazards, MULTI SEAL® is the answer for you! MULTI SEAL® is by far the best flat prevention product on the market today. It is scientifically formulated to virtually eliminate air loss due to punctures and slow leaks. It's the perfect solution for helping you save money on your tires and keeping your fleet running.

MULTI SEAL® is best used as flat PREVENTION rather than flat REPAIR. The application/dosage chart gives recommended treatment amounts of product per tire. MULTI SEAL® recommends pre-treating tires with the recommended amount of product.

MULTI SEAL® Tire Sealants are not recommended for Passenger Cars or Light Duty Trucks. These vehicles have Tire Pressure Monitoring Systems (TPMS) which not only make installation of the product difficult, but the product can also affect TPMS. Additionally, there is some chance that in passenger vehicles with tires designed more for comfort than for a rugged environment, these vehicles might experience balance issues. Larger vehicles, like semi-trucks or 1 ton trucks do not experience the same balance issues (when the product is installed into tires which are already properly balanced).

MULTI SEAL® will not invalidate the warranty on your tires because it does not affect the tire. There is no sticky residue left on the tires. It will not degrade the tire, nor will it cause issues with the rim.

**Long term field evaluations show extended tire life  and prevention of 95% of tire failures form punctures and under inflation.

MULTI SEAL® Frequently Asked Questions.


Does the MULTI SEAL® really work? 

Demonstrated over millions of miles driven by trucks and in various other uses in heavy machinery, tire maintenance costs are greatly reduced, as is loss of productive time caused by tire failure.

How large of a puncture will it seal?

MULTI SEAL® PRO HD 2500 formula routinely seals punctures to 3/4”. MULTI SEAL® Armor 3500 formulation seals punctures up to 1 ¼ inches in tires 18 ply or larger. 

Is it like “slime”? 

“Slime” is aN adhesive based product which might temporarily seal a leak. Unfortunately, it also dries out in the tire carcass and over time loses its effectiveness. MULTI SEAL®is a glycol based product which doesn’t harden inside the tire and is entirely water washable.

Will it freeze or is it flammable?

MULTI SEAL® can withstand temperatures to 30 below. It is not flammable either. The base product is propylene glycol (similar to anti-freeze), and contains no glues or adhesives. It is not flammable, and will not cause your tires to heat up. It is a completely inert product, and has corrosion protection for both the tire and the wheel.

How is MULTI SEAL® installed?

Typically MULTI SEAL® is pumped in through the valve stem after the valve stem core has been removed and the tire deflated. You may use either a pump on a gallon container, 5 gallon pail pump, or the injection cart which measures the correct amount per tire. Tires are then re-inflated.

Will MULTI SEAL® damage the tire or the rim? 

No! There is nothing in the product which will cause damage to the tire/wheel assembly.

Does MULTI SEAL® affect the balance of the tire? 

MULTI SEAL® is not recommended for use in passenger cars or light duty trucks/SUV’s. Properly dosed tires will have no imbalance issues.

Is MULTI SEAL® effective in sidewall punctures? 

Yes, sidewalls are more difficult to seal, but we see sidewall punctures up to ¼ inch sealed in MULTI SEAL® treated tires.

What makes MULTI SEAL® so effective? 

MULTI SEAL® is a glycol based product which uses synthetic fibers including Kevlar and other special components. MULTI SEAL® will stay liquid throughout the life of the tire. When a puncture occurs these components are pushed into the puncture site by tire pressure which instantly seal the puncture. It’s like plugging the tire from the inside out. 

Does MULTI SEAL® help prevent blowouts? 

Yes, most blowouts are caused by under inflated tires caused by unnoticed slow leaks. At highway speeds, these tires heat up, causing the blowout. MULTI SEAL® is very effective in stopping these slow leaks.

Can a tire with MULTI SEAL® be patched? 

Yes, because MULTI SEAL® is water washable, a puncture site can be cleaned, buffed and patched.

Will MULTI SEAL® prevent leaks around an embedded puncture? 

When a puncture occurs, the escaping air carries MULTI SEAL® to the hole. The fibers cling to the side of the puncture and form a “filter” which entraps the fillers. A plug is formed which seals the leak instantly with almost no air loss. As the tire flexes under load, the fiber/filler mass compresses to form a dense and permanent plug. The process is the same whether or not the penetrating object remains in the tire. The process will repeat itself for each additional puncture.

Can MULTI SEAL® be used in a tubed tire?

Yes it can be used, but the effectiveness reduces to 70%-75% rather than the 90%-95% in tubeless tires.

Will I be able to get an accurate pressure reading? 


Can MULTI SEAL® be installed in tires with pressure monitoring? 

NO! Because the location of the tire pressure monitor, in most cases, you will not be able to install MULTI SEAL® in those tires. If you try to install MULTI SEAL® in to those tires, you will more than likely clog the valve stem, and it will require some effort and headaches to unclog the valve. Most pick-ups 2009 and later are federally mandated to have a tire pressure monitoring system. Most passenger cars also have them. Therefore, we recommend use of MULTI SEAL® in farm equipment, construction equipment, trailers, semi-trucks, and off road equipment like 4-wheelers, golf carts, and riding lawnmowers. We do not recommend installation in any passenger car or light duty truck.

Can MULTI SEAL® be used to fix a flat?

It can be, but the most effective use is to prevent flats in the first place by having MULTI SEAL® installed in the tire before the puncture occurs.

Can MULTI SEAL® be used in liquid filled tires? 

MULTI SEAL® offers a product that is designed for use in water-filled tires. This special formulation is Hydro 1500. Ask your sales rep for more details.

What types of equipment can use MULTI SEAL® tire sealant? 

MULTI SEAL® is routinely used for flat prevention in vehicles ranging from wheelbarrows and bicycles to heavy earth moving and other construction and farming equipment.

How much MULTI SEAL® should be put into each tire? 

Dosage rates are based on tires sizes, so different tire sizes require different amounts. Application charts will show the recommended amount. More is not always better.

Can MULTI SEAL® be used to help balance tires? 

While MULTI SEAL® was not specifically engineered as a balancing fluid, we can report that many of our “over the road” customers report that MULTI SEAL® works great as a hydro-balancer in semi-truck tires.
