Latex sealants work by flowing toward punctures and coagulating around the breach—but the sealing particles suspended in that latex determine how quickly the hole closes and how large a puncture the formula can handle. Orange Seal's regular formula packs what the company calls nanites: solid particles in multiple shapes and sizes that migrate toward damage and build a rapid seal. The result handles punctures up to 1/4" and slices up to 3/4", which covers thorns, glass shards, small nails, and the kind of sidewall nicks that catch riders off guard on rough pavement or rocky trails.

The 16oz Refill sits in the middle of the size range—enough for four 29er mountain tires or eight road tires, making it practical for riders maintaining a single bike through a full season of top-offs. Sealant life runs 30 to 45 days under normal conditions, though heat and dry climates accelerate evaporation while cooler temperatures extend longevity. Monthly checks keep things fresh; spin the wheels after topping off to redistribute sealant across the casing interior.

Temperature tolerance extends down to 11°F, suitable for three-season riding in most climates. The latex compound coats the entire tire interior from bead to tread cap, creating a film layer that adds secondary protection against small punctures over time. When the sealant eventually dries, it leaves a thin residue rather than the chunky latex balls that some competing formulas produce—easier cleanup when refreshing or swapping tires.... Read More
