Mr Campbell Made putting the sealant in so much easier.
Mr sellen how much easier is this! should have got it sooner. add sealant with much less fuss and mess
Tricky Wiggins Good for injecting sealant but poor for extracting it.
Steve Made measuring in the sealant an easy job.
Mr Powell Worked very well, never spilled a drop.
Mr Mannion Makes the job a lot less messy and far easier than trying to squeeze a small bottle down the removeable core.
Mr Poissant No complaint, work as described. I wish there was a quarter turn valve at the opening to keep the sealant from coming out while screwing the end to the presta valve.
Joseph Great, no more waste and mess on the floor.
VinnieBiker I change rear tires fairly often so bought this just to make life easier for install and fluid top ups. It's a STANS product so it should work good. It has a threaded end which is better than the others on the market which just slide onto the valve.
Mr Willcox Used this with my new Beto tubeless air tank inflator and together they make going tubeless so easy.
Pepito Easy to use, eliminates the mess.
Mr Jon Pickup I needed to siphon off some latex solution to reuse in another tyre so this seemed the best solution. I didn't find it the easiest of processes but that was just me. As far as getting the correct amount of latex solution into a seated tyre this works very well.
Mr Takahashi It is an essential item for adding sealant. The sealant that uses the sealing crystals will clog, so pour it directly onto the tire.
Mr Desai Best method of getting sealant into your wheels.
Mr Reynolds Easy to use saves excessive mess all over the work bench!
Mr Choo Its a tube injector so u know how much sealant you're putting in. no more guessing. Very pricey though.
junkyjunky Can't wait to try this out, hoping this will save me the mess and work of unmounting and mounting a tubless tire.
Mike Makes it easy to install REGULAR SEALANT, NOT Race Sealant
Mr san pedro Must have tool specially when fitting a non tubeless ready tire
Mid-Sussex Cycle This tool is critical to reducing mess and waste when adding sealant. it is possible to go without this tool, and it is pricey for a simple tool. However, simply remove the valve core, screw this on, add fluid and inject the required amount. Recommended but costly.
Mr Crawford Excellent product and saves a lot of mess
Mr Ryan Quick and easy to use leaves no mess
NigelThomas Really helpful piece of kit; strongly recommended
JB Simple and easy to use
Mr Peglar I had watched a few videos online reviewing how you can put Stan's sealant into a tube and put small cuts into it and the sealant will 'heal' the tube. Needless to say I was intrigued and sceptical at the same time. I went ahead and purchased the sealant and Stan's 'The Injector' to put in my tubes. Luckily or otherwise I ended up with a puncture from a thorn in a tube (with removable core) the previous day. So I figured this would be the best 'test piece' as it wasn't fitted to a bike anymore and would replicate a 'good' type of punctures I get. I 'injected' half a syringe of sealant into the tube, pumped it up so the tube was hissing loudly, I then closed the valve core (after disconnecting the pump) and span it like a hoop around my arm (to mimic how it would be if fitted to a moving bike). To my amazement the hissing stopped nearly immediately and the tube kept the majority of air I had put into it. I then left it over night and checked the tube, it was still pumped up and sealed (has remained that way for around a week now). Needless to say it was promptly applied to all my bikes with removable cores. I have covered approximately 1000 miles on various bikes, both on and off road and have had no preventable punctures (stone cutting tyre side wall doesn`t count). To remove presta style valve cores you will need a seperate tool, however everything else you require is included. As a foot note, the sealant can make a mess when 'The Injector' is removed (no matter how careful you are) so make sure you keep a rag handy.
Mr Foster Quick and efficient delivery and makes the application of the sealant hassle free
Plummer This works well for adding sealant via the valve. Just screw in the black connector to the valve (after removing the core) and use the measuring marks on the side of the syringe. Easy.
kelsall Good for measuring the correct amount but this does not come with the tool for removing the valve core on Stans valves so had to take tyre off rim and use it to pour in sealant. Was less messy than before..
park Easy to use.. no spillage
Mr Murray Does the trick, makes topping up with sealant a breeze! :)
Dave P Works fine with Schrader valves (includes tool to remove valve core) - not tried with presta yet
TomR I have successfully used conventional syringes previously. The Stan's is physically expensive, but makes the the job quicker cleaner, and less of a chore. So well worth the money if you are into tubeless.
Matt W Helps to make changing or refilling tubeless tyres a breeze!
Brian Makes adding No Tubes fluid into tyres and inner tubes very easy, no mess or waste.
Mr Robinson Seems expensive but it works really well. Getting the slime in with minimal disturbance to the seal is worth it - given the frantic pumping I normally need to get them reseated!!
Mr Thorp Makes adding sealant a less messy affair!
BC_Dog Clean and easy to use. I bought this because the picture has a brass connector, but it came with the black plastic connector that everyone now carries. The Injector works well and makes the job of filling sealant a no-brainer.
Mr Bailey Seems expensive but makes life so much easier - if you run tubeless get one!
Mr Wakelin As others have said, have the right tool for the job makes it much simpler and this injector just makes the job of filling the tyre with sealant so much cleaner and simpler.
Mr Crook Expensive for what it is put makes using stans sealant very easy. Good tool for the job
Mr Pelley Makes going tubeless effortless. Don't settle for less. Yes it is a 'nice to have' and not essential but for the hassle free stans injection it is perfect.
Mr Moores So much easier than trying to pour into the tyre before completely installing it. A prime example of having the correct tool for the job and making life easier for yourself.
Mr Jordan Makes a messy job simple
Mr Forsyth The screw down cap with this saves mess and also gives a good seal to remove liquid. Super service from Merlin and delivered next day
Mr Heyes If you have hard to fit tyres, you know the ones that take two people to fit because they are that tight, this saves you and the floor from becoming covered in sealant. Even if your tyres are easy to fit it make setting up a tubeless tyre so much easier.
Mr Moore Useful and much easier than partly removing a UST tyre to top up the Stans fluid. Also works very well to inject Stans fluid into innertubes.
Frank Reid Great idea no more breaking tire bead to install sealant
Dave Perfect for adding more sealant to a tubeless tyre without having to unseat the tyre from the rim.
Mr Armour Works well and saves partly removing tightly fitting tyres. Easy to use . Pleased with the purchase.
Mr taylor Wow v pleased with this, I know it's 'just' a large syringe with a hose and adapter but it does th job perfectly . Just make sure you wash it out carefully!! Beats levering the tyre off and trying to pour goop in through a small gap!!
Mr Log Perfect item for purpose Schrader and presta valves included
Mr worley Good product. Helps to save the old liquid left in the tyre when you change them.
Mr Hoyle Very easy to use
Mr Sewell Recommended, saves mess and makes job easy.
Mr Encarnacion The Best Tubeless Kit, I bought from Merlin Cycles and excellent value as well!
Mr Whitworth Handy for replacing old sealant without having to de-seat the tire.
Mr thorpe Great product does the job
Jon Moore Very useful for using sealant with existing tubes. Couldn't use with the tubeless setup as Mavic valves don't have removable cores, but there you go... live and learn as they say. Have used with tubes in other bikes, so still a useful addition to my toolbox.
