Tire Sealant - 4 oz

Amazing Sealant

So far this sealant is amazing. It is a little tough on your valve cores, have to clean then more often, but other than that I haven't had to use a tire plug once since starting to use this sealant. If I have gotten a puncture I didn't even know about it!


Delivery very good , don’t know if the sealant is any good and I hope I don’t find out anytime soon but very easy to use with the tube on top of the bottle which as I like to apply the sealant through the valve was very useful all in all a very good product and service

Our new house brand.

We're a small shop in Vermont and we're pretty nerdy and particular about making sure we can do the best job possible setting up tubeless. We're also devout proselytizers of the technology. So we definitely want to offer the most effective and reliable tubeless products we can. Black Ox is easily the best sealant we've used and we've made the change to Black Ox as our house brand tubeless sealant.

Amazing product!

My Son is an avid mountain biker and to say he’s easy on equipment it and understatement! He’s been riding with the Black Ox sealant for a few months now and we can’t being to tell you how well it works over the Orange seal and Stans we’ve used in the past. Trail punctures seal up almost immediately unlike the Orange Seal or Stans where we had to roll the tire back and forth to make it seal. The carbon fibers help plug the while the sealant dose it’s job to seal it! I will continue to use this product!
