We met NJ Chapman Builders & Sons, a Devon-based firm, at the Westcountry Farming & Machinery Show 2025, where they visited our stand and watched a live Air-Seal demonstration. After seeing the product in action, they purchased Air-Seal from us and pre-installed it in their tyres.
Now, a year on – and as we prepare to return to the Westcountry Farming & Machinery Show again next week – they’ve shared their experience after running Air-Seal across their vehicles in real working conditions.
“Attending
a local show we were shown how powerful the Air-Seal product is. A technician
had an inflated tyre on a stand and proceeded to drive a nail into the tyre. He
then drew the nail out and instantly the Air-Seal product filled the hole. It
only took seconds to repair itself. Remarkable.”
“We
have a van that has been customised to take dogs. The process has resulted in
us not being able to carry a spare wheel. Always in the back of our minds, we
thought what would happen if we were unfortunate enough to get a puncture — and
even worse, with the van full of customers’ dogs.”
“After
seeing the demonstration, we bought the product from Air-Seal and installed it
in all four wheels. We had peace of mind knowing that if a puncture ever
occurred, we would at least be able to get back home.”
“One
day I noticed the head of a nail in the tyre of the dog van. Now was the time
to test the product. I got a pair of pliers and eased the nail out and
instantly the hole repaired itself.”
“We’ve
now been running that tyre on the van for more than six months without any loss
in pressure. With the tyre being in good condition, we were reluctant to change
it as we feel sure the tyre company would have written it off. However, the
peace of mind this product has given us has allowed us to continue and get full
use of the tyre.”
“Update: all eight of our vehicles now have Air-Seal installed. A truly incredible product.”
After a full year of real-world use, this testimonial shows what Air-Seal delivers beyond a live demonstration – lasting protection, reduced downtime, and genuine peace of mind.
If
you’re visiting the Westcountry Farming & Machinery Show next week, come
and see Air-Seal for yourself and watch the product in action on our stand.
