Orange Seal - Endurance Formula Tubeless Bike Tire Sealant | Long Lasting, Fast Sealing | for MTB, Road, CX and Gravel Bicycle Tires

Seals tires well, no Stanimals. Does dry out (endurance lasts longer than original) so I add a few ml every 4-6 weeks. Including a dipstick would be nice Orange Seal.

Love 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.

Ive had this injected for close to a month now, and so far its worked perfectly. I initially put the same amount of sealant on both my Minions, but it seemed that my rear tire was leaking a tiny bit of air over the course of 4 days (ridden once), so I ended up putting in an additional 1.25 oz, which seems to have done the trick. Using this Along with the KOM sealant injector worked really well on the tubeless stems I purchased. Had no issues with clunks getting stuck in. Some people complain about a smell in other agents. Didnt notice anything with this, but I didnt go out of my way to smell it either. I havent noticed any punctures yet (hopefully I can just avoid those altogether) but Ill update my review in the future for anything I notice.

Ive primarily used Orange seal on my bike. Not for any reason, I am new to the whole MTB scene... It was just one of the first better reviewed sealant Ive seen. My impressions of this bottle is VERY good. See, I bought brand new tires and immediately caught a hole in them. The stock sealant from the bike shop install wasnt able to cut it, the hole was too large for that. But I didnt feel like buying new tires are the time either so I patched the hole myself and bought new sealant ( this stuff ). The tubeless install went flawlessly. This sealant works. After a couple of weeks though I started losing air pressure. At the end of a ride my tire would eventually be really flat. I figured it was the patch work... patches are supposed to just be temporary after all. But just for the heck of it I topped off my sealant because I didnt hear any leaking. Just like that problem solved. A few more weeks and a couple more rides later and my tire still has the same amount of air in it as it did before. This stuff just works. Time will tell on if it can seal tire damage but in terms of a tubeless tire install and sealing, the sealant just works.

Works great would recommend

Bike 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.

Did not contain the filler attachment as shown in the pictures

Sealed the multiple pin hole leaks in the side walls of my Vittoria 29er tires. Stan just wouldnt do the trick.

I ride about 6k miles annually. I’ve been using tubeless tires since about 2000, back when tubeless tires didn’t really exist, and all there was for sealant was Stan’s. Orange seal is my favorite lately. With good tubeless tape (I love muc off) and if you replace it about every 6 months, you’ll be done with flats unless you regularly smack rocks with your rims.

Use in all my bike tires
