paulBy far the best tubeless sealant I've used for tubelss road tyres. Easy to apply & easy to clean off your bike if you do get a puncture. Excellent service from merlincycles as always.
Mr HollinghurstGreat sealant. Easy to use. Quick delivery from Merlin.
raymondBeing a newbee to tubless i choose this band after reviewing many. Would help if it had a ml scale on the bottle, i didnt pour it through valve anyway. I measured 60ml and poured it in the tyre before closing it. The tyre was leaking at the valve area when trying to seat so i swilled the sealant around the valve area wich sealed it also nipped uo valve a bit more put 90 psi in tyres. 3 rides 90 mile later no problems and little daily .pressure drop
Mr RyanEasy to use, has worked well before and this one was no exception
SteveThis sealant is the most reliable I have ever used. Great for Mtb and road pressures
Stuzz552Simply the best sealant I have used. I know it works and I trust it in all my tyres MTB & Road.
Mr PerrottSo much better than nthe others i have tried in the past, very pleased
Angela HartI've been using Orange seal for years. It lasts well and hasn't let me down. Top stuff!
Mr SmithReally easy to use and mess free. One of my tyres had a wee cut in it and it sealed it instantly.
Mr WrightWorked perfectly - 20ml into 700C tyres
David HawleyGreat product, works well. Excellent service from Merlin cycles too.
JustinPurchased first bike within last 10 years. Converted to tubeless using Orange Seal endurance. Application was easy with the included bottle. I just marked the bottle approx halfway to gauge amount to put in tyres. I used half the bottle in each 29” tyre. Haven’t had a puncture yet, so can’t comment on performance. I went with the endurance for longer lasting and decide to sacrifice some sealing ability for this
Mr LingsUsed with Gravel King tyres on Hunt rims. Sealed without any problems. Have only been using it for 2 weeks, but no problems so far.
STGood sealant, the applicator works well but the sealant itself does not last as long as I thought an "endurance" named sealant should.
Mr BRAVAKISThe best tire sealant !!!!
GohVery easy to use with the injector. Just wished the bottle had some volume markings, had to rough up some markings with a marker to see how much sealant I was adding.
JamesReally good sealant, has been great at sealing up cuts and pretty big holes, lasts well too. Recommended.
Mr RosenzweigI used the sealant for the first time in my tubeless continental's. On my second ride a got two cuts in my rear tyre, the sealant did its job!! Sealed up nicely. All I needed to do was put in a bit of CO2 to bring the tyre pressure back up and I was off and riding. Happy days!!
SimonExcellent product, the twist lock applicator makes it very easy to use.
Mr van kesselNoozle works well. Bottle needs volume markers on the side to see how much is used. The sealant is very frothy and it is difficult to judge how much goes inthe tyre. Haven't had a flat yet- touch wood.
CManFirst time doing tubeless, but this seems to be working just fine! Time will tell how fast it dries out.
Mr KaponenGood product, works like it should.
Dr HaleGreat product. Slow to dry out so needs topping up less often. Seals well.
