Orange Seal Endurance Tubeless Sealant

Sealant That Goes the Distance

The worst time to find out your sealant dried up is halfway through a ride with a thorn in your tire. Orange Seal Endurance is formulated to last longer between top-offs, up to two to three times longer than the standard formula, so you spend more time riding and less time checking tires.

It seals punctures up to 1/4 inch, works in both tubeless tires and tubes, and holds up across changing temperatures and altitudes, which makes it a favorite for long gravel races and big mountain days. The 4 oz bottle comes with Orange Seal's injector system and a dipstick, so you can add sealant through the valve and check levels without breaking the bead. The 16 oz refill keeps the bench stocked for a few wheelsets.

Whether you're setting up a new tubeless gravel build, topping off a mountain bike before a trip, or keeping road tires sealed through a long season, Endurance keeps you rolling.

About Orange Seal. Orange Seal started with a bad day on the trail. In 2008, a group mountain bike ride kept stopping for punctures that the sealant of the day couldn't plug, and the crew's resident "mad scientist" decided to build a sealant that covered every kind of riding. Today Orange Seal makes sealants and tubeless accessories for road, gravel, mountain, BMX and e-bike tires, and its sealant has been used by pro road teams.
