Subzero Tubeless Tire Sealant

The Subzero formula is specifically engineered with a lower freezing point, allowing it to remain liquid and effective in temperatures as low as -20F. Standard sealants often thicken or freeze in extreme cold, which prevents them from sealing punctures effectively.

Yes, it functions perfectly fine in warmer weather. However, because it is optimized for extreme cold, it may dry out slightly faster than standard sealants when used in consistently hot climates.

This sealant is designed to plug punctures up to 1/4 inch (6.35 mm). It uses a blend of solid particles, which Orange Seal calls nanites, to quickly create a durable seal over larger cuts.

It is compatible with most tubeless tire systems. Because it is latex-based and biodegradable, it is generally safe for use with standard tubeless rims and tires, but you should always check your tire manufacturer's recommendations regarding sealant compatibility.

Even in cold conditions, sealant eventually dries out. We recommend checking your levels every 30 to 60 days, especially if you are riding frequently, to ensure you have enough liquid inside to seal potential punctures.
