WTB TCS Tire Sealant – Tubeless – Ammonia-Free – 4 oz

WTB TCS Sealant is a tubeless-specific tire sealant designed to seal punctures quickly while remaining stable inside the tire for extended periods. It is optimized to work especially well with WTB tire compounds but performs reliably in other tubeless systems as well.

Riders choose WTB TCS Sealant when they want fast sealing without harsh chemicals, odor, or frequent maintenance. The formula focuses on mechanical sealing rather than evaporation, which helps it stay active longer.

Key Features

• Instantly seals punctures up to 1/4 inch (6 mm)
• Mica particulate with tackifiers for mechanical sealing
• Ammonia-free formula
• Water-based synthetic latex
• Designed to remain fresh for months after installation

Service / Ownership Context
Because this sealant does not rely on ammonia evaporation, it typically remains liquid longer than traditional formulas. Regular inspection is still recommended, especially in high-volume tires or extreme riding conditions. Clean out dried sealant residue during tire service to maintain reliable sealing.

Fit & Use Signals
• A good fit for riders running tubeless systems exclusively
• Commonly chosen by riders sensitive to natural latex or ammonia-based sealants
• Works well for riders who want long-lasting sealant with fast sealing
• Not ideal for tube-based tire setups
• Not the right choice for repairing large tire cuts or sidewall damage
