FAQs

Off-road formulations: typically include fibre reinforcement (small synthetic fibres suspended in the sealant fluid) that bridge larger punctures up to 8-15mm. The fibres also help the sealant grip the tyre interior at lower rotational speeds typical of off-road riding. Best for trail, motocross, ATV, and quad use where puncture sizes are larger and speeds are lower. On-road formulations: smoother chemistry without fibre reinforcement, suited to higher speeds and smaller puncture sizes (3-6mm typical). Best for road-motorcycle commuting and touring. The formulation type is on every product page.

Modern tyre sealants distribute evenly under tyre rotation and shouldn't significantly affect tyre balance for typical road and off-road use. However: very high-speed road use (160+ km/h sustained) can cause sealant centrifugal-displacement and unbalance; over-dosing (more sealant than the manufacturer recommends) creates a heavy zone and unbalance; some specific tyre constructions (run-flat, ultra-stiff sidewall) may interact differently. For race-and-track use, dedicated race sealants or no sealant is preferred. For typical road, off-road, and trail use, manufacturer-recommended doses don't cause noticeable handling changes.

Most modern tyre sealants are formulated for tubeless tyres — they seal punctures by depositing fibre and chemical material at the puncture site on the tyre interior. Tubed tyres have an inner tube that punctures alongside the outer tyre — sealing the tube requires a tube-specific sealant formulation. Many sealant brands offer separate tubed-tyre and tubeless-tyre formulations; some offer dual-purpose products. Always check the compatibility note on the product page; using tubeless sealant in a tubed tyre may not seal effectively.

Modern sealant formulations typically remain effective for 2-5 years inside the tyre, depending on operating conditions and formulation type. Heat (engine-bay heat for some applications, road-surface heat in summer) and freeze-thaw cycles in winter accelerate sealant degradation. Some sealants dry out and form a residual deposit after 2-3 years, losing puncture-sealing capability while remaining inside the tyre. For high-mileage and high-temperature applications, refresh the sealant every 2-3 years. The shelf-life and in-tyre life are listed on every sealant product page.

Every product is backed by our Fit Guarantee. If a part is incompatible with your machine, you can return it hassle-free. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will arrange collection. For other returns, email us first to obtain a Return Merchandise Number before sending. Returns are accepted within 30 days of purchase, in original packaging, on UK orders. A restocking fee may apply on returns where the buyer has changed their mind. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and "Check where we deliver" confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa.

Within Tyre Sealant, Bike/ATV/Quad covers the tyre sealants formulated for motorcycle, ATV, quad-bike, and small-vehicle tyre applications — covering off-road and on-road motorcycle tyres, all-terrain vehicle (ATV) and quad-bike tyres (commonly used in agricultural-yard work, light grounds-maintenance, and recreation), and the matching small-volume application accessories.

Parts for Machines supplies bike/ATV/quad tyre sealant across the trade and contractor ranges. Sealants for these applications are formulated for the specific operating conditions — off-road environments where puncture risk is high (thorns, rocks, debris), variable speeds and load conditions, and the typically-tubed or tubeless tyre constructions used on motorcycles and ATVs.

We are an authorised distributor and seller of OKO and Air-Seal across the bike/ATV/quad tyre sealant range. OKO covers the broadest selection — OKO Off Road sealant (formulated for motorcycle and ATV off-road applications, with fibre reinforcement to seal larger punctures), OKO Magic Milk and other on-road formulations for road-motorcycle applications, and the matched application pumps and injectors. Air-Seal extends the range with specific motorcycle and small-vehicle formulations.

Product pages list the sealant formulation (off-road with fibre reinforcement; on-road for higher-speed road use; specialist all-weather variants), the maximum puncture size the sealant can repair (typical 3-15mm depending on formulation), the operating temperature range (typical -25°C to +60°C), the bottle or container size (typical 250ml-1-litre for individual-tyre application; 5-litre containers for multi-tyre service), the recommended dose per tyre size, and any specific compatibility notes (some sealants are not suitable for tubeless tyres; others not suitable for tubed). Repeated freeze-thaw temperature cycling typical of trail-bike applications can degrade some sealant chemistries faster than continuous operation. Trade pricing on bulk and contractor orders is available; contact the team via WhatsApp 07754288583.
