Heavy-Duty Puncture Protection That Keeps You Moving

Air-Seal® Heavy Duty tyre sealant is built on over 20 years of advanced technology, designed to significantly reduce punctures and slow air leaks in tyres. It provides reliable, long-term protection for both on-road and off-road heavy-duty vehicles, including multi-axle equipment.

Businesses using Air-Seal® benefit from fewer tyre repairs, reduced downtime, and improved operational efficiency—helping lower costs and increase profitability across their fleet.

When a puncture occurs, the sealant is instantly activated. Escaping air and centrifugal force push the sealant directly into the damaged area, where reinforced fibres and fillers form a strong, long-lasting plug. This process minimises air loss and can occur repeatedly, delivering ongoing protection without the need for reapplication.

XM Logistics has used AirSeal for our exploration vehicles for over 3 years. Saving on constant tyre replacement, while reducing costs and down time. Great Product put simply, works and works well.

I used Air Seal in the tyres of my Honda Africa Twin motorcycle.I got a puncture in the remote Kimberley’s and the product did its job.The tyre deflated overnight and I pumped the tyre up the next morning and I was able to ride a few hundred kilometres to a town where I was able to replace the tube and fit new tyres.I highly recommend Air Seal especially if you’re going to be in remote areas.

Our small Company has used Air-seal across all six of our vehicles, With our vehicles starting early mornings it give confidence knowing that when the lads turn up for work that there won't be any flat tyres to start the day, as the price for a call out at that time is greatly more expensive than the price of Air -seal being fitted, let alone the downtime that would be lost. It pretty much eradicated any punchers within our fleet, enabling us to be more efficient and reliable for our clients.

I've been using Air Seal Products for the last year and a half in all of my 4WDs and cars, and I honestly can't recommend it highly enough. I've driven thousands of kilometres all over Australia, including Cape York, the Simpson Desert, and the Victorian High Country, and throughout all of those trips I haven't had a single puncture that Air Seal couldn't handle. Knowing my tyres are protected gives me confidence when travelling in remote areas where a flat tyre can quickly become a major problem. Air Seal has proven itself time and time again, and it's now something I won't run a vehicle without. If you're serious about touring or off-roading, this product is absolutely worth it.👍

Huxley Racing had a great experience with AirSeal Australia. Their product gave us extra confidence heading into race weekend, and it’s reassuring knowing your tyres have that added protection. On top of that, the team has been awesome to deal with and are passionate about supporting off road racing. Thanks for the great service we’ll definitely keep using AirSeal and would happily recommend it to others.

I was a firm believer that internal products like Air Seal did not work effectively. I have since changed my mind after using the product in multiple loaders for a waste disposal facility. We went from having to do a puncture repair every other week, at the cost of $1000 or more dependant on repair and tyre size, to running tyres out nearly bald without failures. Some may look at this as lost revenue, but we think this is great service provided. And the money 'lost' on repairs is made up by happy customers and continued business from said customers. We have also used this in plenty of bobcat/skid steer/lawn mowers etc....and have had great customer feedback. I highly recommend this product to anyone looking to save some money and machine downtime. The only con to this product is that it can be a bit messy, and you may spend a bit of extra time cleaning a wheel assembly before fitment of a new tyre, although not much time. Keep in mind that depending on what product you use may differ your results, we use the Heavy Duty variant, we have had great success with this.

I have used Air Seal in my 4WD and camper trailer tyres now for over 5 years travelling over some of the roughest roads across Australia and have never had a problem with the product. In that time, nails have been discovered at tyre changeover without any tyre deflation experienced.

As an owner of multiple machines mowing hundreds of hectares working along many and various roads. We encounter on a daily basis a lot of rubbish in the grass that cant be seen. On any given day we experience puncutres. We have started using Air Seal towards the end of this seasons mowing. I have noticed that our down time due to punctures is now down considerably. We still get puncture from tears from bottles and strips of metal in the grass etc however we are not getting as many. We will be starting next season in Spring, September 2026, with all 8 machines and all spare tyres we carry with Air Seal in the tyres to see how we go. Gino Canberra Mowing
