As a tire tester I rely on several sealants in my travels. To see my MTB and Gravel Tire collection, go to the "more ads by this user" link above.
I dont like the pouches, they are hard to use and wasteful. I package this in easy to use squeeze bottles with an open nozzle that fits the valve stem directly with the core removed. NO MESS.
Pro tip. I personally never put sealant in a tire until I have used it on one ride, just in case the tire has a defect I cant live with. Removing a wet tire is a waste of expensive new sealant and an unnecessarily messy exercise. Through the valve stem is the only way to go, with valve core remove, the core is never clogged this way.
This stuff has no ammonia, so no butyl degradation. Ammonia stabilized latex formulations void many tire warranties and dry up quickly in our dry weather. This will last up to a year.
Muc-Off delivers the goods with No Puncture Hassle sealant. The special formula has microfiber molecules which fill the bigger holes and tears, while the advanced liquid latex forms a strong seal for porous areas or small holes instantly. No Puncture sealant also contains a unique UV detection system that highlights any punctures you haven’t seen during your ride.
This bottle is enough for 2 normal size tires. $9ea or $5 with tire purchase. I also have 2.5 oz squeeze bottles for $5, perfect space saving size for topoff on the trail.
