Squirt Seal Tyre Sealant With BEADBLOCK®
Squirt Seal with BeadBlock® is a puncture-sealing tyre sealant for tubeless and tubed bike tyres.
It uses a mix of latex, microfibres and BeadBlock granules to help seal punctures while you ride. When air escapes through a hole, the sealant moves to the puncture, the latex starts to close it, the microfibres help plug it, and the BeadBlock granules add extra reinforcement for larger holes.
"My preferred sealant. I've tried a few different brands (Stan's, Orange etc) and this is on par with Orange in terms of sealing larger holes. It's not easy getting Orange sealant in NZ so I switched to Squirt with zero regrets."
It’s ammonia-free, biodegradable, easier to clean than harsher formulas, and designed to last well inside the tyre without drying out too quickly or making the tyre walls stick together.
Good option if you’re setting up tubeless tyres for gravel, MTB, road, commuting, or just want better puncture protection without carrying your entire workshop in your back pocket.
