For more context, after injecting through syringe or bottle, when I pull the rubber tube out, it will start coming out
jonxmack on
How much are you putting in? Have you tried rotating the wheel slightly to allow the sealant to settle in the bottom then removing the tube?

Rotate the wheel with the syringe/bottle still attached so it can flow down the tyre. Also don’t do it on a kitchen chair next time 🫣

Err, I don’t think you are supposed to put the sealant in while the tyre is under pressure…
contrary-contrarian on
lol just turn it so the valve is at 90 degrees… also you really don’t need much sealant. Maybe 1oz at most

Something you can try if the tire is already sealed on the rim is squeeze it a bit with your hand before injecting, to push some air out of the tire, then slowly loosen your grip on the tire with that hand while injecting, basically creating a little suction in the tire to pull the sealant in.
But that said I have no idea how this is happening to you, also been tubeless for years and it’s never exploded out. Your tire isn’t like somehow full of air when you’re trying this is it? Don’t know how it would be with the core removed but….?

My method is to press the tire down, pushing some air of it, before I begin injecting the fluid. As I press the plunger, I ease up on the tire, so that it draws in more fluid. When the tire has almost returned to it’s normal shape, I stop pushing fluid in, remove the injector, rotate the tire slightly to make certain the fluid isn’t pooling right below the stem, and then I deform the tire again to push some air out, insert the injector, and start again.

Are you using Stans valves by any chance? I had this same issue because the opening is tiny at the end of the valve body, choked off by the molded rubber piece. They don’t pass straight through like other brands. I drilled them out and it’s much easier to fill now.

A rag held around the injector / stem when you pull out. Rotate your wheel so the valve stem if only a few minutes below the horizon. On a clock, think 3:30 and 8:30.
Your sealant is thick, and your stem may be clogged or very narrow. I use a park tool injector, with stans sealant, and try to use tubeless valves that allow the injector to slide all the way into the tire.

Are you pouring, or injecting with a syringe? I have a syringe that connects to the stem so I just spin the tire so the stem is at 3 or 9 o’clock so everything goes to the bottom. Seems pretty straight forward.

have air in your sealant injector and push that through after the sealant.

I struggled with the same thing and finally 2 years ago got [THIS](https://komcycling.com/products/tubeless-sealant-injector-valve-core-removal-tool?variant=32680604139606&country=US¤cy=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gQT=1) and it has worked extremely well. Easily worth the $13 or so. You can either use the syringe to go down through the valve, or if your valves are too small like mine are, you can use the screw tip to push down onto the valve and create a good seal. My order of operations is (assuming the tire is already on the wheel):
-Remove valve core
-Turn wheel so that the valve is at like 4 or 8 o clock (6 being the ground)
-Inject sealant using the flexible tube with the screw tip attachment held closely on the valve to create a seal.
-Slowly remove injector from the valve.
-Reinstall valve core
-Rotate wheel around a few times
-Pump tire back up

Valve at the 4 or 8 o’clock position, not 6. Squeeze the tire a bit when injecting, then release the squeeze as you pull off the sealant injector to suck the sealant into the tire.

When you empty the syringe into the tyre you are adding some volume to it and pressuring it a little. To take this pressure back out, just pull the plunger back before removing the syringe. Do this in addition to injecting it with the valve at 3 or 9 o’clock and you should avoid this, or any spitting from the valve.
