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

Used this my first time setting up tubeless, and it was as easy as could be. Flows well, sealed quickly. I found it easiest to use a bottle of water to flush the remnants out of the tube for storage (dont want to put it down the drain). The only improvement I can think of is that it would be nice if there were ounce markings on the bottle to get a more accurate idea of how much you put in.

Did not contain the filler attachment as shown in the pictures

Love the product because it is eco-friendly and has saved me from quite a few flats in my tubeless tires. Unfortunately, the cap shattered in transit (probably due to the lack of cushioning). It leaked out all over the inside of the box and on a textbook book that was ordered. I’m still not sure why this was packaged together since there were other books in this same order. I specifically ordered this product because the picture online is a picture of the shop bottle, meaning that it comes in the white bottle with a safety cap. The product that came to me was the retail version. Only buy the white shop bottle if you can!

Ive had good luck using this product over the past few years. Ive just had normal pinholes in tires and this has sealed them very well. However the main reason that I like this product is that it lasts longer than Stans! Whenever I use stans, I have to refresh it every few months because it would dry out and turn into a little rubber ball inside my tire. I would have to break the bead and pull it out at least once a year. I dont have this issue with orange sealant. It stays liquid even a year later. My tires are also holding pressure very well between rides.

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.

My 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.

I wanted this small 4oz bottle of OS Endurance for long bike trips. I think Orange Seal is the best however the bottle I received was marked with an expiration date of 07/22/2022. How important is the expiration date? What is the shelf life on this product? Would have been five stars if not for the expired date.

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

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.

Having struggled with several flats - I had literally lost confidence in MTB tires on rough trails. The tires look gnarly at the treads but are actually soft esp at the walls and bottom. Tubes were a no go disaster. I took the leap to tubeless and having installed them and tried a few - orange is the way to go on any rim. Other might corrode, but this one does not. Add some every 3-6 months to ensure your seals continue and you are good for any number of rides. A miracle cure for flats - dont leave home without a fill.
