Product Information
Full details
The WTB TCS Tubeless Tyre Sealant is an ideal solution for mountain bikers, gravel riders, and off-road enthusiasts looking for a reliable, eco-friendly way to maintain tubeless tires. Its key benefit is the rapid sealing of punctures up to 6mm using an ammonia-free, synthetic latex formula that remains effective in cold climates down to -9.4°C; however, riders should be aware that, like all sealants, it requires periodic replenishment to maintain optimal liquid levels for effective puncture protection.

FAQs
Is this sealant compatible with all tubeless tires?
Yes, it is designed to work effectively with any tubeless-ready or UST tire system.
How often should I replenish the sealant?
It is recommended to check your sealant levels every 3 to 6 months depending on local climate and riding frequency.
Will the ammonia-free formula corrode my aluminum rims?
No, being ammonia-free, this sealant is specifically formulated to be non-corrosive to rims and tire casings.
Can I use this sealant in CO2 inflators?
It is generally recommended to avoid using CO2 to seat the tire, as the cold temperature can cause the latex to clump prematurely; use a floor pump or compressor instead.
What is the shelf life of the 32oz bottle?
When stored in a cool, dry place with the cap tightly sealed, it remains effective for several years.
Troubleshooting
Sealant leaking from the valve stem
Ensure the valve core is tightened securely and verify that the rim tape is not damaged or obstructing the valve seat.
Tire loses pressure overnight
Check the tire bead for proper seating and ensure the rim tape provides an airtight seal; if both are correct, add more sealant to plug micro-leaks.
Sealant is not sealing a small puncture
Shake the wheel to coat the puncture area with sealant and ensure there is enough fluid inside the tire.

Setup, Compatibility & Care
To set up your tubeless system, ensure your rims are properly taped and that the tubeless-ready tire is seated firmly against the rim bead. Use the gradients on the 32oz bottle to measure the correct amount of sealant according to your tire manufacturer's specifications. Shake the bottle thoroughly before application to ensure the particulate is evenly suspended. Apply the sealant either through the valve stem (with the core removed) or directly into the tire before seating the final section of the bead. Periodically, check your sealant level by rotating the tire and listening for a sloshing sound or by inspecting the tire through the valve. If the tire loses pressure frequently or you do not hear liquid movement, add more sealant to maintain protection.
