Orange Seal Endurance Tubeless Bicycle Tire Sealant

Maximum protection. Maximum uptime.

Whether you're running tubeless tyres on mountain, gravel or road bikes, this 946 ml mechanicsized bottle of Endurance Sealant is designed to keep your tyres sealed and rolling with minimal fuss. With industry-leading longer life and strong sealing capabilities, its a premium choice for riders who want fewer flat repairs and more ride time.

Why youll love it:

• Extended service interval This Endurance formula is built to last up to twice (or more) as long as standard sealants meaning more time riding and less frequent top-ups.

• Big-hole sealing capability Formulated to seal larger holes and side-wall slices (e.g., up to ~3 mm punctures and ~12 mm slices) while also handling porous sidewalls.

• Cold-weather performance Able to perform well down to approximately 23 0C, making it a reliable option even for cold-weather rides.

• Workshop-friendly size The 946 ml bottle (32 oz) is ideal for multiple wheel setups or high-volume usage by mechanics or serious riders.

• Broad compatibility Works with most tubeless systems as well as inner tubes, giving flexibility across bikes.

Ideal for:

• Cyclists who run tubeless setups on MTB, gravel, road, or commuters and want to minimise downtime from flats.

• Workshops, bike stores or heavy users needing a bulk size to service multiple bikes.

• Riders tackling harsher terrain or conditions (eg. rocky trails, thorny tracks, cold weather) where extra sealing reliability is beneficial.

Technical highlights:

• Longevity: Up to 60-120 days between top-ups under many conditions.

• Sealing thresholds: Punctures up to ~3 mm, slices up to ~12 mm in suitable tyres.

• Temperature performance to approx 23 0C.

• Non-corrosive, safe for rims/tyres.

What it means for you:

Install it and forget about it this sealant handles the small but ride-ending punctures so you dont have to stop mid-ride. The large 946 ml volume gives you plenty in hand for multiple uses without constant restocking. For riders who prioritise uptime, the Endurance formula is a smart investment.

Pro tip:

For best results:

• Ensure your tubeless tyre and rim are properly seated and inflated.

• Make sure the sealant is well distributed (rotate/tip the wheel) so it covers fully inside the tyre.

• Check the fluid level periodically and top up if you notice decreased performance (especially after many rides).

• Keep unused fluid tightly sealed this size is great for the workshop, but once opened store it properly to maintain efficacy.
