Tubeless Tire Sealant Injector for Stans No Tubes Tire Sealant Muc Off Slime and Orange Tire Sealant Adding Valve Core Remover Included

Not sure why Stan’s or Orange Seal didn’t create or distribute this.It provides a no-mess way to add sealant.Just as importantly, it provides a way to extract sealant to visually get a look at how much is in the tire. It is vastly superior to other methods of checking sealant levels.

Add half a star for a 4.5 star product.My only disappointment is I'd like a better, more secure, connection to the valve stem: the threading does not quite match. Nonetheless, I had minimal drip with the short valve stems on my tubes with the screw on connection, and also very minimal overflow when using the "snorkel" adapter with the longer stems on my commuter bike.The core removal tool could have used some knurling to provide more friction to aid in the grip, but it did work just fine, as is.All in all, well made, well priced and functions just fine.

The best feature is all the connecting pieces are threaded and require a twist to lock on. This detail will prevent the injector parts from accidentally separating when adding sealant to the tires, which is why I had to replace my old one. After several years of use, the flex tubing would sometimes detach from the syringe when pushing the plunger to inject sealant. Problem solved.Btw, ignore the "discard after use" labeling. I plan to use this as a sealant injector for several years.

So, tubeless bike tires are a significant improvement in bike performance because we don't have to deal with flats and wheels are lighter.Anyhow, half the battle is creating an effective seal between the tire bead and rim.The fewer times we have to break the seal the better.These sealant injectors make it so we need not break seal to examine the amount or quality of fluid in the tire.Now, we can remove the valve core, insert this injector into the valve stem and slurp out the existing fluid.Simply add more sealant with this injector to ensure proper puncture and seal performance, all while NOT having to break the bead seal. It's the best it can be with this setup.If the fluid looks watery, stop using a high-powered hose or power washer on your bike.Those force water past your tubeless sealant seal, putting water into your tubeless wheel, causing the sealant to fail. (Trust me on that. I used to power wash my bike and made that mistake, costing me the last race of the season b/c the sealant was diluted)Anyhow, add one of these to your arsenal of tubeless tools to make life somewhat easier.

Orange Seal Endurance contains glitter and sand to help plug and seal larger punctures. The nozzle and attachments on this injector are small enough to filter out some of the sand and glitter, or they'll even get clogged by those additives when sucking up sealant.The valve core removal tool is very nice and the injector works well enough with other sealants.

I strongly prefer filling sealant, and topping off, through the valve. Remove valve core, inject sealant, move on with your life. This product has both a flexible tube insert as well as one that can screw on. For presta valves, the flexible tube is really the only option. I like that I can accurately measure how much sealant is going in using the increments marked on the side of the syringe. My one quibble is that the syringe is too small to add sealant to a new gravel/mountain bike tire. 60ml is too little for a tire that size. So you have to do it twice, but it is not a big deal. The valve core tool they include is a nice bonus, and given that the syringe and tube are just plastic, I guess they need to include it to justify the price.

Syringe came broken with a shattered hole in the center of it. The plastic seems to be made of very poor quality. The durability of the syringe is questionable, at best.Getting sent a replacement and will update my review after using a functioning one...

I bought this to inject sealant into my bicycle tires. I also bought a 32 oz. container of sealant, so I needed something that I could easily manage to inject the goo into my tires. The injector is quite manageable and easy to fill and clean. Most sealants come with a filler tube, but you are never certain when you have squeezed in the correct amount. This injector gives you more control.

Good enough.

makes topping up your tire sealant easy.

It work perfectly

Tool looks well built and the whole presta fitting is such a great idea. No more mess when adding sealant to my tires.
