If you’re looking for just the sealant and already have the injection system, then the Orange Seal Endurance Tubeless Sealant is your go-to option. It comes in various sizes, but all fit with the screw-top of Orange Seal’s injection system — should you already have that. The formula itself is designed to last two-three times longer than regular sealant, meaning you don’t have to fill up the tire as frequently because of it drying out. This premium latex sealant features what Orange Seal refers to as nanites, solid particles of multiple shapes and sizes that quickly seal punctures up to 1/4-inch. It’s also a bit lighter weight to keep weight down. Orange Seal goes a step further and formulates the sealant to be eco-friendly, helping the environment and your peace of mind.
