Stan's Tire Sealant is a very thin, low viscosity liquid that coats the inside of the tire and carries with it specially formulated sealing crystals. This means that unlike foaming sealants, Stan's reaches punctures quickly and seals them effectively, from smaller holes to larger cuts.

Just two ounces of Stan's Sealant fills most road or MTB tires and the sealant stays liquid for 2-7 months on average.* Plus, the Stan's formula is non-hazardous, non-toxic and safe for the environment.

This 32oz bottle fills up to 16 tires.

*Riding in arid climates or storing the bike in a hot area will requires more frequent monitoring of sealant levels. Special anti-freeze agents allow the sealant to be used in environments as cold as -30° F.

Works I guess

This is the only sealant I've ever used so I've have nothing to compare. I've had very few punctures in my riding lifetime so i guess it's good. I'll continue to stick with Stan's

Does what it should

Had my first puncture last week on my Conti 5000 TL. Happened about a mile into my ride. I stopped, gave the tire a quick spin, put my finger over the puncture to give it time to seal, and after a minute, I was on my way. I lost about 10 psi but felt no need to top off the air. The cut was a little jagged, maybe a couple millimeters or a 16th of an inch, so I'm thinking a small piece of glass, but the air and sealant blew it out so don't really know what it was. All I know is I stopped but for a minute and was soon on my way.

Tried and true sealant

I've used tubeless for road, cx and mtb for many years now. The sealant has sealed countless flats. Tubeless can be a pain to set up and but once dialed in it's great-often, but not always, seals punctures, can prevent catastrophic fails, and improved ride quality are all pluses. Stan's used to be the only name in the game but now there are many alternatives. Some wheel manufacturers (Shimano) void their warranty if you use Stan's due to a small amount of ammonia in it and worries about nipple corrosion. Stan's disputes this and I have never had a problem. Between Stan's and Orange Seal Stan's seems to dry out faster but I have had Orange Seal fail due to the latex drying out but there still being plenty of whatever the liquid base is. That said, I use both since my LBS stopped carrying Stan's-I bought some through this site. And they're both pretty pricey, but worth it overall in my opinion.

Works well.

I've tried this and Orange Seal and prefer Stan's for the value. Stan's has performed well for me in sealing tubeless mountain tires, even ones that are not tubeless-specific.

NO FLATS since using and almost 10,000 miles!

This stuff is GREAT!!! I no longer ride with a saddle bag and don't bother carrying a spare tube I trust this product that much. In the event of a flat someday, I will find my way to a bike shop, hop on a train to get home or just phone AAA and get them to pick me up. Replacing the presta valve is tricky and messy after adding sealant and so now I just bring new parts to my local bike shop and let them do it. I just pay for the labor. There is misinformation about how this product can be used. I contacted Continental and it is safe to use this sealant in Continental road tubes. Many bike shop are unaware of this and think this product is solely for tubeless tires. Expect the sealant to last up to 6-8 months which is about the time frame before I need to replace my tires so I just start from scratch and replace with new tubes along with new tires and sealant. IMPORTANT Make sure your air pump has a hose with a lever release nozzle and NOT a THREADED nozzle. After adding air, I accidentally pulled out my presta valve, TWICE, while unscrewing the threaded nozzle and sealant exploded into my face. Local bike shops can replace the hose with a lever nozzle on floor pumps for about $10, parts and labor included. I'm no longer concerned about getting flats which was a big worry over the Winter months. I only wish I found out about this product years ago.

Reliable

I've been using Stan's for several years on gravel and road tubeless tires. Seals small holes without me even knowing and seals bigger one's after spraying a bit.

Works as advertised, plugs small and medium holes and keeps you riding.

Purchased Stan's sealant when I started riding my road bike with tubeless tires. The sealant works. I haven't had to repair a flat tire in 4 years. I also use Stan's sealant in my cyclocross tires. How do I know it works? Occasionally I will have a puncture and I will hear air leaking and notices a small amount of sealant exiting the puncture hole. After a few revolutions the puncture is sealed, and I keep on riding. I regularly pull goat head thorns out of my cyclocross tires and watch the sealant fill the holes while a small amount of air escapes. The sealant does evaporate so you need to add more sealant, frequency depends on temp and humidity. One thing to be aware of, most of the sealant is liquid with lots of particulate suspended in the liquid. I think the particulate is what actually fills the puncture holes. When you get to the bottom of a bottle of sealant there is usually not much particulate left. At that point your better off not using the remaining sealant. Best to start a new bottle with more particulate. Check out Stan's No Tubes web site on for useful tips on going tubeless and using the sealant.

As good as Flexseal

I put 4-6 oz's in and suffer air loss overnight.

Hey there! Unlike with a normal tubed system that would hold air for a longer period of time, tubeless set-ups require regular pump ups, and should be inspected before every ride. If you have any further issues feel free to contact us at: [email protected] 1-800-682-0570

Excellent value!

I use this sealant on cyclocross bikes and have found it to be long-lasting and easy to use, especially when paired with the Stan's syringe.

A must have.

I was skeptical about going tubeless for a long time. I avoided it until I bought a mountain bike and could really see the benefit of running at lower pressures.

With this stuff on board I don't worry about flats and I get to enjoy super grippy tires. It's so easy to use, it cleans up easy, and the punctures I've actually seen have all sealed up quick.

Well worth the purchase, my shop will never be without a bottle again!

It's good to keep this stuff around in quantity for my MTB and cross bikes. Swapping tubeless tires or fixing flats is less tedious when all the tools are readily available...Yeah and the bulk price is way better than the little single serving bottles.

The stuff you want!

I have used Slime and Air Lock over the years and I have been thoroughly impressed with Stans. Really nice to use less sealant per tube and my instinct is that Stans seals punctures more quickly than the competitors, reason being that I have had to top up my tires less frequently using Stans than either Slime or Air Lock...I assume I have experienced a roughly equal number of puncture events using each of the sealants. I was initially put off by the limited servicelife of Stan's-sounds like it's supposed to dry out after a year or something-but if you live in a high puncture environment (as I do...Alb, NM) then chances are it won't be able to dry out before you need more any way.

Stans fluid is by far the best for filling holes and longevity in the tire. I�ve tried a few other sealants but I always return to Stan�s.
