Air-Seal Products

What Air-Seal Products does

Air-Seal Products Limited, founded in 2000 in Somerset, UK by Alex and Kerstin Burnand, manufactures and distributes a range of liquid-based mechanical tyre sealants for pre-emptive puncture repair and tyre pressure maintenance. Its product portfolio comprises five branded SKUs - Heavy Duty (Off-Road), Heavy Duty (On-Road), Armour-Seal, Hydro-Seal, and Air-Seal - differentiated by puncture-repair capacity (13mm to 30mm) and use case, all built around a proprietary aramid fibre and filler-particle formulation that mechanically interlocks at the penetration site within 1-3 wheel rotations. The product has an indefinite shelf life, never hardens inside the tyre, and is reusable across tyre replacements.

The company generates revenue primarily through one-time product sales in packaging sizes from 1-litre bottles to 20-litre pails, sold via three complementary go-to-market motions: a UK-based direct sales team targeting enterprise fleets (Royal Mail, Argos, UK Armed Forces, government departments), an international distributor network spanning 80+ countries, and a Shopify-based e-commerce storefront launched in 2023. Distribution is also supported by trade resellers such as Mole Valley Farmers and Harpers Feeds, and a sister company, Air-Seal Installations, provides application services. Marketing is heavily event-driven, with active presence at 12+ UK trade shows featuring live nail-into-tyre demonstrations, supplemented by social media activity across Facebook, Twitter, LinkedIn, YouTube, Instagram, and TikTok.

Air-Seal Products is privately held and founder-owned with no external investment, no parent company, and a headcount of approximately 10 staff. Its served verticals include road haulage, waste management and recycling, mining and quarrying, agriculture, construction and demolition, grounds care, OEM/dealer channels, local authorities, and the UK Armed Forces and government departments. The company's RASE Burke Innovation Trophy finalist recognition in 2026 reflects its standing within agricultural engineering innovation in the UK.

Core offering

Air-Seal Products Ltd manufactures and sells liquid-based mechanical tyre sealants that use proprietary aramid fibre technology to provide instant puncture repair lasting the life of the tyre. The product range covers five grades—Heavy Duty (Off-Road), Heavy Duty (On-Road), Armour-Seal, Hydro-Seal, and Air-Seal—designed for commercial fleets, agricultural, mining, construction, grounds care, OEM/dealer, and government/military vehicle applications. Sealants are applied as tyres are fitted and seal rim, bead, and slow air leaks while maintaining optimal tyre pressure.

Product overview

Air-Seal Products Ltd manufactures and sells a range of liquid-based mechanical tyre sealants for puncture prevention and tyre maintenance. The product portfolio consists of five branded sealant products: Heavy Duty (Off-Road), Heavy Duty (On-Road), Armour-Seal, Hydro-Seal, and Air-Seal. All products use a common technology — a proprietary combination of aramid fibres and filler particles suspended in a carrier fluid that coats the inside of the tyre and instantly seals punctures when they occur. The products differ primarily in puncture-repair capacity (ranging from 13mm to 30mm) and are formulated for specific use cases: standard on/off-road applications, heavy earthmoving conditions, and water-ballast-filled tyres. Heavy Duty is the flagship and most widely used product across both on-road and off-road sectors.

Emerging players

• Stan's NoTubes: Stan's NoTubes makes sealant primarily for bicycle and powersports tubeless tyres, using a latex/fibre liquid sealant concept similar in mechanism to Air-Seal. Comparable product technology but narrower vehicle scope; useful proxy for technology trajectory and brand-building in sealant categories.

Comparable emerging players benchmarking Air-Seal's growth trajectory in agricultural and fleet segments.

Directly comparable to Air-Seal as a competing tyre sealant manufacturer targeting puncture prevention for cars, trailers and small equipment.
• AME International (tire sealant division): AME International supplies tyre management consumables including sealants, balancers and repair materials to commercial and industrial tyre dealers worldwide. Comparable as a broader tyre-services supplier with overlapping sealant SKUs in fleet and OTR segments.

Direct peers
