Key Features Explained

The stated 6 mm puncture figure describes the listing’s sealing claim; it does not establish how a particular tire will perform in every situation. The temperature claim specifies optimization down to 15 F (-9.4 C), not a guarantee of sealing at all temperatures or conditions.

WTB describes the formula as curing sealant particulate into a flexible repair. The listing also says its synthetic latex is intended to reduce the risk of allergic reactions. This is not a guarantee that the product is allergy-safe; check the product labeling if latex sensitivity is a concern.

What to Compare Before Buying

  • Tire system: Check that your specific tire and wheel setup calls for tubeless sealant and that this formula is suitable for it.
  • Volume: Compare the 4 oz (118 ml) bottle with the amount required for your tire setup. Follow the tire and sealant instructions for application amounts.
  • Conditions: If cold-weather use matters, compare your expected conditions with the stated optimization down to 15 F (-9.4 C).
  • Repair expectations: Treat the listed 6 mm figure as a stated claim, not a promise that every puncture can be sealed.

What Is Included

The stated package quantity is one 4 oz bottle. No additional tools or accessories are specified.

Before You Decide

Confirm that your bicycle’s tire setup accepts this type of sealant, that 4 oz is an appropriate bottle size for your needs, and that the stated temperature range suits your intended conditions. Follow the product labeling and the tire maker’s instructions for use and handling.
