Stan's NoTubes2oz Tire Sealant Injector(Return to Product Page)

This thing did NOT thread on to my presta valve. Big mess trying to use it.

For what it is, I'm happy. A little leaky but it's nice to have a dedicated sealant syringe

This does not fit on presta valve stems. If dual-threaded means that it can thread onto a presta valve, it is not dual threaded. I even tried turning a valve extender upside down and it would not thread into the injector. I don't see any way to use this with a presta valve or valve stem.

Doesn't seem to screw into presta value core, have to hold in place while injecting thus a little messy.

First time using this product. So far so good.

No problems.

Straightforward and makes a potentially messy process fairly easy. If you have tubeless make your life easier and get one. Saves time and money going to a bike shop.

If you're going tubeless you're going to want this. It just makes life so much easier. A great solution that is simple and effective. Plus it cleans up easy.

The pump is easy to use and accurate.

The injector makes refreshing the tubeless sealant very simple. Much easier and less messy than unseating the tire for the refill.

Perfect device coupled with a large Stans sealant bottle to inject sealant into the valve core.

Doesn't work if you don't have removable cores in your presta valves. Most do not!

Maybe the best $10 I've ever spent on bike gear. I've tried every other method for adding sealant to my tubeless tires and nothing is as easy and clean. The brass adapter makes a tight seal on the valve so all the sealant goes into the tire not on the floor. Shake the bottle of sealant and squirt it directly into the injector and you don't have to worry anymore about the sealing crystals settling out and being left behind when you add sealant. Are there cheaper ways to do the job? Yes, but do yourself a favor, don't get cheap at the wrong time.

I used a cheap, online sealant injector for years until it gunked up to the point where the plunger bit the dust. I bought this �name brand� injector which was noticeably cheaper, thinner and more fragile plastic. The nozzle that the hose attaches to broke off when trying to remove the hose to use the injector with just the nozzle. This was a complete waste of money, and I�d suggest looking elsewhere for something that is a bit more robust.

Great for putting in sealant!

Worked as expected for getting sealant into a tubeless setup without causing a bug messy.

Exact experience from this previous review

One star because it works or it doesn't.

The new injector, with the new cheap plastic fitting does not work. I bought a replacement injector after having used my old injector for the past several years. The old injector had a brass fitting and worked great. The new injector has this piece of junk plastic adaptor. I could not get it to screw on to my presta valve at all. I ended using my new injector as spare parts for my old one. Stans needs to get rid of the substandard plastic injector and go back to the brass fitting.

I use my Stans sealant injector for both Stans No Tubes sealant (for our mountain bikes) and Finish Line sealant (for my gravel bike). It works great for getting a measured quantity of sealant into my tires. Its easy to clean, store and re-use.
