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

I like the texture of this stuff, as it creates a kind of latex layer around the inside. That can help the sealant do its thing. On the down side, I live in a hot and humid climate. I find that I need to check on the condition of the sealant every three weeks. It can separate and dry up in a summer month.

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.

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.

Did not come with tube to install into tubeless tire

I am a nail magnet. I on every ride get a flat. My life was miserable and I cursed those bicycle designers. Then came my new tubeless ready bicycle. I, a novice. Put a tape on the rim. Installed Valve. Added this Orange stuff and pumped. The tire I added this on already had well over 20 punctures. I fully expected it to spray orange goo all over the die. I just couldnt believe watery orange water with black fine powder in it can seal my punctures. Jesus Martinez.. 3 wooze a little bit of orange goo and it stopped. Pumped the bike to 50 psi and it held. Holy guacamole. I went through the bushes and riverbeds and pulled out dozen goathead. Air leaked when goathead was popped out but quick spin on the tire sealed it. Not even a whole turn, half turn and it stopped leaking air. After 3 months or so I am finding out that it may not be sealing it permanently. Tire continuously leaks air a bit. It loses 5 psi in a week of being idle.. maybe 5 psi a month.. it depends. So I check and pump at least every week or before I go out. But that is only maintenance it takes. I now have utter confidence that Orange will hold air. I made a 70 trip and I did not worry about a puncture. My bike is a gravel bike and I carelessly jump in to gravel trail whenever I see them. I dont believe I will have to carry my bike 11 miles again because it had a goathead. I am baptized and born again.

Return user and always satisfied!

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.

Should be enough if you have multiple bikes. If you have just one bike, this should last all year long. Good value. Wish it would have came with the filler tube, so of you do have one you may want to get one to make adding sealant to your tire easier. I do find the Orange sealant tends to dry up quicker than other brands, but from my experience it seals better when you get a puncture. With the large bottle you can top off every 2-3 months.

Using it on four mountain bikes and one gravel bike last about 4-6 months at a time.

I found out about Orange Seal after much, much aggravation with Stans. When I used Stans, my tires bled constantly from the sidewall. Specialized told me we recommend not using Stans as it has corrosive properties not compatible with our tires. Kenda - ate through the sidewalls. Then one day out on a brand new $60 tire, I got a cut about 1/4 long. Already really pissed at how much MTB tires cost, cutting a brand new one like that sent me into orbit. I took the tire apart, cleaned it extensively, put a patch on the inside of my tire where the cut was (Im running tubeless), let it dry. Tested the hold by hand before putting the tire back together on the bike. I really squeezed & pushed it, the patch seemed solid. Put Stans in, aired up the tire. Checked again - yep, holding air. Loaded up & drove off to hit the trail. Get on the trail and 15 minutes into my ride, the tire goes flat. Cussing like a sailor, I walked back to my truck, threw my stuff in & went back home. Took the tire apart, and the patch is laying in the tire not glued to it. Stans ate the glue off. Refusing to give in to tossing a $60 tire in the trash, I went to a couple bike shops explaining what had happened. One shop recommended Orange Seal, saying thats what they use in the shop. I once again, went through the process of patching the cut in my new tire. Put it all back together, checking the air constantly for any sign of loss. Went on my ride. It held! In fact, it held so well that I rode that tire until the tread was gone with the patch STILL holding! Ive been sold on Orange Seal ever since. Ill never use Stans again. It costs a couple bucks more which I didnt like, but it does work. I think both brands are about 200% profit to the manufacturer which is why I gave it only 3 stars on Value for Money, but if you have to pay, might as well pay for something that works.
