They went through five different formula revisions to ensure TCS Tubeless Tyre Sealant is the best option for quickly and confidently repairing ¼” (6mm) punctures.

Their unique formula cures sealant particulate within the puncture to create a flexible, long-lasting repair.


Optimised for Temps Down To 15f° (-9.4°c) - They made sure their sealant performs best in the most common riding temperatures. An undesirable amount of antifreeze is required in order to ensure a sealant performs properly at extremely low temperatures. Accepting higher minimum temps allowed WTB to improve sealing performance by reducing the amount of antifreeze and replacing it with additional synthetic latex.

Ammonia-Free - TCS Tubeless Tyre Sealant uses a tackifying process to seal punctures rather than relying on the evaporative effects of many ammonia-based formulas. As a result, their sealant performs better in wet, unforgiving conditions where other sealants have trouble clotting due to reduced evaporation.

Synthetic Latex - Synthetic latex reduces the risk of an allergic reaction for individuals with allergies to natural latex products. Synthetic latex also keeps the sealant fresh for many months of riding.

Completes The TCS Tubeless System - TCS Tubeless Tyre Sealant is a dependable, thoroughly-tested sealant formula that completes WTB’s patented TCS system of tubeless tyres, rims, wheels, valves, tape and sealant. TCS (Tubeless Compatible System) is their standardised tubeless rim/tyre system designed to meet international ETRTO standards and deliver unbeatable reliability.

Seals Instantly - They made sure TCS Tubeless Tyre Sealant is able to quickly seal puncture caused by anything you may encounter out on the trail. Mica particulate seals within punctures using tackifiers rather than relying on the evaporation process of harmful ammonia. This means TCS Tubeless Tyre Sealant performs consistently in harsh conditions where other sealants have trouble clotting due to minimal evaporation.
