Seal punctures before they interrupt your ride with Squirt Seal Tyre Sealant with Beadblock, a reliable, maintenance-friendly solution for tubeless road and gravel cyclists.

This 120mL pouch delivers a clean, ammonia-free latex formula enhanced with natural microfibres and BeadBlock™ particles that work together to plug punctures quickly and permanently. Effective from -20°C to +40°C, it’s a dependable sealant for year-round use across changing road and trail conditions.

When a puncture occurs, the synthetic latex base immediately reacts to the pressure drop, forming a rubber seal. If the initial seal isn’t complete, suspended microfibres provide additional blockage. For larger intrusions—up to 6mm—the added BeadBlock™ granules reinforce the seal, creating a durable plug that holds under pressure. This formula is also designed to prevent sidewall adhesion and includes corrosion inhibitors for added rim protection. Ideal for high-mileage riders who prioritise mess-free maintenance and consistent sealing performance.
