MilKIT is one of the leading companies in conversion to tubeless riding.

MilKIT's patented valve system is the ONLY one in the market that lets you insert tyre sealant into your tubeless wheel quickly, without ' blobs'.

There is nothing on the market that works neater, faster and more efficiently. Nothing.


What sets milKIT apart ? the answer is simple : EVERYTHING.

Valve: allows the sealant to be sprayed directly into the tyre (no mess, no mess, always being able to check how much sealant is left in your tyre)

Did you know that ? milKIT has KITS ( valve with syringe ) that allow you to keep using your preferred seal. The 'Tubeless conversion' valve system is second to none....

Seal : 100% biodegradable, odourless, fast-acting. The milKIT seal is winner of several independent tests.

Booster : no need for an expensive bulky air compressor to quickly pressurise your wheels/ pop your tyre in the rim. With this booster, time after time, you can do this job yourself quickly and at no cost.

milKIT : Ingenious and sophisticated.


The EUROBIKE award winning milKit Booster is a revolutionary tool that allows you to inflate tubeless tyres quickly and easily without a large and expensive air compressor.
Mount the Booster on the valve and... done !

With the Booster, you can pop the tyre into the rim flange. You can inflate the aluminium canister to 11 bar with a foot pump. Just pump the pressure you need to inflate your type of tyre into the canister. Then place the Booster on the valve , press and the tyre is immediately inflated to the desired pressure.
The lightweight ( 150 gr) Booster is very compact and super eco-friendly as this product replaces the one-time use of C02 cartridges or expensive compressors and you can easily take it everywhere as it also serves as a drinking bottle on the road.


The milKIT valve system is the second product the company makes, and back here awarded a " best of " prize by MTB magazine.

You only need to inject the sealant through the valve after inflating your tyre. This is because the check valves on the valve prevent pressure loss.

  • With the milKIT syringe, you inject the sealant directly into the tyre. No dirt and fast !
  • No risk of clogging !
  • At all times you can check the amount of sealant yourself and quickly top it up if necessary.

NO system is as useful.

MilKIT vragen

  • How much pressure do I pump into the booster?

    The pressure in the booster depends very much on the rim combination and whether the tyre is already inflated. At 6 bar / 87 psi, in most cases only good rim combinations or tyres that are already inflated will work. At 8 bar / 116 psi, most tyres work and only in a few extreme cases the full 11 bar / 160 psi is needed.

  • What size of Booster do I need?

    One of the main advantages of the milKit tubeless booster is its highly efficient air flow: unlike other tubeless boosters, the milKit booster has no hose and therefore no pressure loss - the full air pressure is right at your valve. With so much air shooting into the tyre in an instant, even the small booster is efficient enough to inflate any tyre (except fat bike tyres). So the choice of booster depends on the size of your bottle: perhaps a compact 0.6L / 17oz or 0.75L / 25oz to fit in your bottle cage or the large 1.0L / 34 oz to carry more water on your ride.

  • Can I use the booster with any valve?

    The milKit tubeless booster can be used with any Presta tubeless valve. The milKit valves have the advantage (besides the ability to measure and refill your sealant without letting the air out of your tyre) of keeping the air in the tyre without the valve core in the valve - making inflation easier and more efficient.

    Presta valves with external threads that do not extend to the top of the valve reduce the efficiency of the milKit booster.

  • Does the booster fully seat my tyre on the rim?

    The booster is only meant to pre-pump your tyre so that it sits tight enough on the rim to keep the air in. You then have enough time to apply sealant through the milKit valve, use the milKit syringe and needle to screw back the valve body and pressurise the tyre to full pressure until it pops fully onto the rim.

    If your tyre does not hold the air well after pre-pumping with the booster, you may need to first screw back the valve, bring the tyre to full pressure until it pops fully on the rim, and then reduce the tyre pressure to less than 1.5 bar / 22 psi to apply the sealant into the tyre.

  • Can I use Milkit with other brand valves?

    Our valves are custom-made as they have closed rubber flaps at the bottom.
    This has several advantages:

    • The valves no longer clog up.
    • They keep the air in the tyre even if you remove the valve (easier fitting of tubeless tyres).
    • They allow measuring and topping up sealant with the air pressure still in the tyre.

    You can use valves from other brands, but then you will not benefit from the best advantages offered by MilKit.

  • How much sealant should I put in my tyre?

    Many factors can influence the decision on how much sealant to put in a tubeless tyre. Some tyres "absorb" a lot of sealant, and a few days after fitting, a significant amount of the sealant is gone. This is where the milKit valve and spray system comes in handy: we recommend always checking how much sealant is left in the tyre a few days after fitting.

    Choosing the right amount of sealant also depends on the user's priorities: adding more sealant results in better puncture protection, but makes the tyre heavier. With the milKit valve and spray system, which makes measuring and topping up sealant quick and easy, the right amount of sealant can be tested and optimised step by step without hassle.

    We recommend starting with the following quantities and optimising the right amount of sealant 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
  • Can I make the sealant thinner by adding water?

    Our sealant is a little thicker than the sealant you may have used. It always remains homogeneous, so you don't have to worry about shaking the bottle before use or the particles not being evenly distributed in the tyre.

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

    If you want your sealant to be thinner, you can add up to 30% water to the sealant. This extends the sealant's life and makes it flow better to the bottom of the tyre, but it also slightly reduces the sealant's puncture resistance.

    It is always a trade-off between longevity and puncture resistance when it comes to sealants. You will have to figure out what is the right balance for you. But hey, that's exactly what the milKit spray system is there for, right? To help you understand what happens to the sealant in your tyre.

    An important fact when fitting a new tyre is that a significant amount of sealant "disappears" into the pores of the tyre. We recommend measuring how much sealant is left in your tyre a few days after fitting - this is the amount of sealant for best performance.

  • When should I replace my sealant?

    There are two reasons why you should check your sealant regularly:

    • Drying out of sealant
    • The sealant is getting old

    You should always have the amount recommended by the sealant manufacturer in your tyre. Over time, you will get a feel for how often you should check the sealant. Before a long ride or a holiday, it is always good to check the sealant to make sure your tubeless system is in good working order.

    Sealants also get old and lose their functionality. Old sealant can be recognised by a change in colour or when it starts to dissolve and the consistency looks more like water than new sealant. Old sealant should be removed from the tyre with the syringe. Mixing new with old sealant is not recommended.

    MilKit sealant does not dissolve and only thickens over time. Nevertheless, sealant should be replaced regularly to ensure the best performance.
    How can I wash the sealant off my clothes?

  • How can I wash the sealant off my clothes?

    One of the main advantages of our sealant is that it is water-soluble. So you can wash it off your tools and clothes with water. Make sure you wash the sealant while it is still liquid - once dry, it is made to be strong and durable - and therefore very difficult to remove from clothing.

  • How do I apply the rim tape properly?

    Our tubeless rim tape is made with pressure-sensitive adhesive. This means that pressure must be applied after taping for proper adhesion. When you inflate the tyre, the rim tape will adhere it to the rim.

  • At what temperature do I apply the rim tape?

    For taping, a higher temperature helps, but room temperature (>25°C) should work fine.
