I just ordered this from Amazon for 12 bucks -
I was actually just looking for a decent core removal tool, but this popped up for a very reasonable price. I've been wanting to try the syringe/tube setups. I have no problems checking levels and topping off, as is, but I'm hoping that this will also aid in removal of sealant that's gone bad. In theory, I won't have to break the bead to mop it up with paper towels - I should be able to insert the thinner tube through the stem and in to the tire and then suction it out.
That set up works awesome until something inevitably gets stuck in the thin hose. Then, the attachment blasts off and sends sealant all over your shop. Ask me how I know

. I now use the syringe without any of the hose threaded on to inject sealant. The end of it is perfect to cover a presta valve and there is no risk of it exploding sealant everywhere. I only use the hose to remove sealant before I break down a wheel.
