Orange Seal tubeless tyre sealant 454 g refill — Regular Formula natural-latex, fast seals up to 1/4" for MTB, road, gravel

Orange Seal Regular Formula is a natural-latex tubeless sealant that quickly seals punctures up to 1/4" and forms a lasting internal bond to keep bicycle tires rolling.

Whether you ride mountain trails, gravel roads, cyclocross courses, or pavement, this 16 oz refill bottle supplies a versatile tubeless sealant engineered to work with most tubeless-ready and UST tires. Formulated with natural latex for strong adhesion, the sealant plugs small punctures fast, seals bead-to-rim interfaces, and remains compatible with a wide range of rubber compounds and riding conditions down to low temperatures. The Regular Formula balances flowability for easy installation with durability for repeated, long-term performance.

How quickly will this sealant stop a flat while I'm riding?

Orange Seal Regular Formula is designed to close small punctures almost immediately when noticed and to finish sealing the hole within seconds to minutes depending on rotational speed and puncture size. It remains fluid enough to travel inside the tire while forming a sticky, elastic plug that bonds to the casing.

• Seals typical punctures up to 1/4" quickly.
• Works with rotating wheel force to distribute sealant to the leak.
• Natural-latex matrix forms a flexible internal patch.

Will this product work with my tire type and riding conditions?

The Regular Formula is formulated for broad compatibility across tubeless-ready and UST tires, and it tolerates a wide temperature range for year-round riding in many climates. It’s suitable for road, gravel, cyclocross, mountain, and most e-bike applications where tubeless setups are used.

• Compatible with most tubeless-ready and UST tires and rims.
• Performs at temperatures down to about 11°F (-12°C).
• Engineered not to harm rubber or cause delamination over time.

What size punctures and damage can this sealant handle?

This formula is optimized for small- to medium-size punctures and certain slices; it reliably seals holes up to 1/4" and can bridge some larger cuts. For large gashes or sidewall damage, mechanical repair or tire replacement may still be necessary.

• Seals punctures up to 1/4" cleanly.
• Can bridge some slices—performance varies with cut shape and tire casing.
• Not intended as a permanent repair for major sidewall tears or structural damage.

How do I use and maintain this sealant in my tubeless setup?

Installing the 16 oz bottle is straightforward: remove the valve core if desired, add the recommended dose for your tire volume, re-seat the bead, and spin or ride to spread the sealant. Periodic topping up (typically every few months) maintains protective coverage and ensures ongoing effectiveness.

• Remove valve core for faster filling, then reinstall when finished.
• Shake before use; add recommended ounces per wheel based on tire size.
• Check and refresh sealant every 2–6 months depending on climate and mileage.

Who is this for? Orange Seal Regular Formula is ideal for cyclists who want reliable, fast tubeless protection across multiple bike types—mountain bikers, gravel riders, road cyclists, cyclocross racers, and e‑bike users—looking for a balance of easy installation, broad compatibility, and durable puncture sealing in everyday riding conditions. Choose this 16 oz refill if you want a proven all-purpose sealant to keep tubes out and wheels rolling without frequent intervention.
