Thanks to the nanites – particles of different sizes and shapes – Orange Seal Natural Latex Tubeless Sealant quickly and reliably seals holes. It is available in three formulations: Regular, Endurance, and Sub Zero, which differ in durability, puncture protection, and optimal temperature range. You can find more details in the downloadable PDF "Orange Seal Product Info."

Orange Seal Natural Latex Tubeless Sealant is made from premium natural latex, contains no ammonia, and is compatible with virtually all tubeless systems, as well as standard tubes and tubeless tires.

The conclusion of the Mountain Bike Action comparison test of eight tubeless sealants, which even included the less effective Endurance formulation compared to the Regular, clearly states for the Orange Seal winner:

"In the fourth and final test, we brought out the heavy artillery, a number 2 screwdriver. The massive hole it left forced all four remaining competitors in the race to bow out. However, Orange Seal held out the longest. Since it is still possible to pump the tire up a bit from time to time, bikers should be able to make it home even with a hole this size using Orange Seal.".
