The Muc Off Hey Dipstick! Tubeless Sealant Check Tool was born out of the desire to be able to check out the health of tubeless tire sealant that has been previously installed into a tire without having to dismount the tire. The pink anodized aluminum knob has an ergonomic shape and is knurled to make it easy to pick up and use the tool, and the stainless steel dipstick shaft is thin enough to easily fit through tubeless valve core. Once the dipstick reaches the level of the tire sealant, precisely machined grooves pick up the level of the tire sealant and allows for a very quick check once the dipstick is removed from the valve. In short, this tool will make quick work of checking the health of your tubeless tire system, allowing you to get on the trail more quickly and with more confidence that your tires are ready for whatever is thrown at them.
