Stans NoTubes2oz Tire Sealant Injector(Return to Product Page)

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.

Love that I am not buying the small disposal stan's sealant, this works exactly as it should, easy learning curve.

Stupid easy to use and makes tubeless refills a simple task. A no brainer if you have a removable valve core.

It's Stan's setup. what more is to be said. everything he put together for tubeless works great - just be sure to watch the instruction videos on his website.

I purchased this sealant injector to simplify the installation of Stans Sealant into my wife's gravel bike tires. This worked perfectly fine for me and I had zero issues with any mess or sealant leaking between the hose and the valve stem. I would highly recommend this injector for anyone using tubeless tires and sealant.

Can be a bit messy but works great with Stans NoTubes Tire Sealant.

I just switched to tubeless on both my fat bike and my gravel bike, so I'm new to the whole process, but I have learned that refreshing the fluid in the tires is important and that it helps to know how much to add. This makes it easy to monitor the exact amount going into the tire. I would recommend removing the plunger to add fluid to the injector rather than drawing it in through the tube to minimize dripping , but other than that, this is a very useful addition to my kit.

holds plenty of liquid for both tires.

easy to use. thread on and push liquid in.

Eazy Peezy.

This is the easy way to keep fresh sealent in your tubeless tires. Easy to clean.

Was not easy to use. Sealant leaked out of the vaive onto the floor

Adding sealant is a messy process for me, and I'm never quite sure exactly how much sealant is getting in the tire. Yes, I'm a rookie mechanic with tubeless tires. The sealant injector helped me measure the sealant. The adapter to screw-on the tube to the value stem is helpful. I haven't mastered venting air from the tire as it is displaced from the tire. Rotating the wheel Slightly helps, but I'm open to suggestions on how to vent the air without making a mess. The injector does not have a vent that I can figure out.

Okay, I wasn't really using a funnel! But, I WAS guessing at the volume of sealant I was adding. This injector allows me to add precise quantities, and is easy to clean up.

There are much better products on the market. for the price, not bad, but still messy and the tube feels like cheap vinyl. Spend the money and get something worthy.

Great for added to correct amount without guessing
