> 24 hourI’ve used orange seal for years. It has been dependable and consistent. It works well for keeping my tires inflated and rolling. It is water based so easy to use and clean up.

> 24 hourBike shop, and mountain-biking family members all extoll going tubeless. So far, so good. I did four tires in short order without adapter to valve stem. Highly recommend short You Tube videos to prepare/plan. Another set of hands would have been helpful servicing 29 rims/heavy tires with liquid sloshing around, still managed without spilling a drop.

> 24 hourHad this screw go all the way into my tire. Thought it was hopeless but after adding air a couple times it actually was able to seal and could ride just fine

> 24 hourMy first attempt didnt work as I did not have the tube from the sealant cover the stem. The second time, I was able to firmly secure the sealant tube over the stem and squeeze the sealant into the bike tube. I road the bike twice since the repair and can say it sealed the leak quite well. I no longer worry about minor leaks when riding.

> 24 hourAs for the product, unless youre actually racing where money/prizes/pride is at stake, this is your choice for MTB tubeless sealants. Ive meticulously tested this against Stans and generated a list of pros and cons. While similar overall, the Orange Seal Endurance does edge out the Stans. Both are good sealant choices, but the OSE is better. My main issue with the 32 oz mechanics bottle specifically is, when the item ships, its common to see the seal under the cap broke contributing to leaks. Ive ordered a case in the past and it arrived in a way where it looks like one of the bottles bursted. Orange Seal has to do a better job at using a better seal to resist leaking during shipping and handling.

> 24 hourLove this product, I’ve used it for years. Made this purchase of the smaller bottle specifically to get the included injector. Arrived without injector. Returning it.

> 24 hourIts hard to believe that some foolish people refuse to accept the well documented proof that tubeless tires are far more reliable than tubes. Orange Seal has worked the best for me for over 5 years. All my mountain and road bike are now tubeless and I havent had a unsealable puncture in literally thousands of road and mountain miles. I ride primarily in western Colorado, Utah, and the Big Island of Hawaii. All well known for being hard on bike tires. Tubes are outdated old school tech that has suffered the same fate as rim brakes and steel frames. The nay sayers all love to tell stories of some poor soul the had a sidewall gash and got covered with sealant. They tried to fix it but got all messy and had to call for help. If you put enough miles on bad roads or non groomed trails you may eventually get a big enough cut that is un-fixable no matter what is inside of your tires. Orange seal will seal pretty much seal everything else.

> 24 hourI own a small bike shop in the Adirondacks. Everyone up here runs tubeless, even the roadies. So over the past 10 years I have tried all the sealants. Ive tried making my own, used motorcycle sealant, etc. The best, by far, is Orange. It is EASY TO CLEAN UP and remove from tire treads and sidewalls, seals great and lasts quite long. Its expensive, but its really worth it to us. Id rather set up a wheelset with Orange once, then have to take the wheelset back in and redo the sealant because it didnt seal properly. That costs me money. So in the end the higher price point is actually saving me cash. The endurance I find is good for MTB tires and fat bikes, but the race version works best for road and gravel tires. The endurance is too thick for the smaller tires.

> 24 hourI had Stans NoTube Race Sealant in my tires. That was a fresh conversion to tubeless. I have no prior experience. My son did it for me. It worked well at first, but then my tires started losing a lot of pressure after about a month. I added 3 oz Orange Seal Endurance to the leakiest tire, and 1 oz to the other. I also tightened the valve stem nuts, so I cant say the Orange Seal was the ticket, but I think so. Ive been riding for a few weeks since, and my tires are only losing about half a pound each time I check, and theyre probably losing that in the process of checking them, as I have to use a Schrader adapter with my current pump. I have 650B tires, and ride about 75 miles a week, mostly on pavement. I will continue with the Orange Seal Endurance, as it was very easy to use, and seems to work like a charm.
