milKit Sealant

Many factors can influence your decision about how much sealant to add into a tubeless tire. Some tires “soak up” a lot of sealant and a few days after installation a significant part of the sealant is gone. This is where the milKit valve and syringe system comes in handy: we recommend always checking the amount of sealant left in the tire a few day after installation.

Choosing the right amount of sealant also depends on the priorities of the user: adding more sealant will result in a better puncture protection but make the tire heavier. With the milKit valve and syringe system, that makes the measuring and refilling of the sealant quick and easy, the right amount of sealant can be tested and optimized step by step without a hassle.

We recommend starting with the following amounts and then optimize the right sealant level from there:

• Road / gravel 40-80 ml / 1.4-2.7 oz
• 26” MTB 60-80 ml / 2-2.7 oz
• 27.5” MTB 80-100 ml / 2.7-3.4 oz
• 29” MTB 100-120 ml / 3.4-4 oz

Our sealant is a little bit thicker than the one you might have used. It always stays homogeneous so you don’t have to worry about shaking the bottle before use or particles not being distributed evenly in the tire.

The sealant covers the inside of the tire nicely, but that also means that less sealant flows to the bottom, which can then be measured using the milKit syringe. As a result, the “mobile” part of the sealant that you measure will be smaller when compared to the total amount of sealant in the tire.

If you prefer your sealant to be thinner, you can add up to 30% of water to the sealant. This will increase the lifetime of the sealant and make it flow to the bottom of the tire better, however, it will also slightly reduce the puncture fixing ability of the sealant.

It’s always a trade-off between longevity and puncture fixing capability when it comes to sealants. You’ll have to find out what is the right balance for you. But hey, that’s exactly what the milKit syringe system is here for, right? To help you understand what’s happening with the sealant inside your tire.

An important thing to understand when installing a new tire is that a significant amount of sealant “disappears” into the pores of the tire. We recommend measuring the amount of sealant left in your tire, a few days after installation – that will be the amount of sealant for best performance.
