Stan's no tube Preventive Liquid Tyre Sealant, 473 ml

Good value sealant. After discovering a large bulge in my rear tyre it was time to fit a new one, realised I had run out of sealant so opted to buy this as it seemed the best value and a well established brand. Fitting the new tyre was a bit of a pain (literally) but once on and seated proceeded to pump 60ml of sealant into the tyre via the valve, everything went well with no messy sealant all over the place, pumped up the tyre and gave the wheel a good shake-bounce-spin session, no leaks or loss of pressure 👍. Have since done a 20 mile ride and tyre and sealant are so far a great combination. Would definitely recommend Stan’s.

After hitting the MTB trails hard and puncturing numerous inner tubes, I decided to go tubeless, best decision I've made when it comes to trail riding.Allows lower air pressure for more stability, best of all not had a single puncture since I used this stuff.I fitted tyres then injected the fluid through the valves, filled with air and rotated the wheels for a few minutes and job done! Excellent product, great price, works out so much cheaper and easier than inner tubes. 100% recommend.

Works ok .

saw a photo here with someones bike that had a nail in one side and out the other.. he said it was still inflated when he got home.... so i was sold.Put this in my ride on lawnmower 2 years ago.. haven't had to check the pressure since.. (and that was a pain in my rear) its now in my car, my trailers, my wheel barrows, my lorry and I even put it in inner tubes.Iv been putting 250ml in car/lorry tyres. its ither working a charm... or just making me feel good. 12 stars! give me a bucket of it and make it cheaper.

Perfect for mountain bike tyres, seals up all manner of punctures and would recommend for anyone wanted to work with it.It lasts for about 6 months I would say before I replace it, which makes it far cheaper than inner tubes on a total cost and to certainly a massive time saver.Not sure how it works for Roadies as I've seen some people it won't cope with insane pressures or go in an inner tube - which it never should and if you are trying to, you've kind of missed the point of tubeless.Convert to tubeless, shove this in and your life will be almost complete apart from all the other things you are yet to doRemember to shake a lot, and don't leave it unused in the garage

Easy to use, easy to follow instructions on the product, which will last about 8 - 12 months depending on how often your ride and style of riding.

Effective sealant and great for topping up. Bought this to top up my tyres where it had deflated sat over the winter. Sealed perfectly. Using a syringe to put it through the valve helps

I was sceptical of tubeless for a long time, but the price of innertubes is only going up.Stans no tubes where recommended to me so thought I'd give it a go. not the cheapest option but seems to work well.I tried, just for interest what would happen without any tyre sealant, and the air leaks out in a few minutes from 40 psi. Put this stuff in and it was like a miracle.I think I've had one small puncture on the front and maybe lost 3-4psi, but its sealed itself.rear has held pressure for a couple of weeks and 100 miles of cycling.
