Following the success of MilKit’s crowd-funded innovative valve system and lightweight portable tubeless booster, MilKit have now brought their very own sealant to the market. Yes, there are around 300,000 other sealants on the market, that all claim to be able to seal up any small holes made in your tyres quickly and without a messy fuss, much like blood clotting a small cut. What makes the MilKit sealant different to everything else out there? Read on to find out…

Swiss Engineered MilKit Sealant

First up, MilKit has some nice claims on the environmental friendliness of its sealant. Unlike many other sealants, MilKit does not contain Ammonia or other chemically aggressive ingredients (green points). It is also anti-allergenic and MilKit say it will not cause corrosion of your tyre rubber or rims.

One of the main advantages offered by the new sealant is that it should always remain as a homogeneous liquid and so you don’t have to remember to shake the bottle before use. The microfibers in the solution, which play an important role in sealing large holes, should therefore be distributed optimally and always ready everywhere. MilKit say this means that the sealant has a significantly improved performance and fixes slits in the tire up to 6 mm in length. In the tire, the sealant does not decompose into rubber particles and an aqueous
residue, a common issue with other products, but it dries evenly and slowly and therefore remains functional longer than comparable products.

The sealing effect of the microfibers should also work very well at high pressure, making the sealant suitable for use in high PSI road and gravel tubeless tires. MiKit claim the sealant shows better adherence to tyre walls than thinner latex products, guaranteeing full coverage.

It can also be used in combination with CO2 cartridges and can be easily diluted with water and washed off if necessary. It’s usable temperature ranges between -20°C to 50°C (-4°F to 122°F), thus you’ll be hard pushed to find an environment in which it will fail.

Pricing and Availability

The MilKit sealant is available online and from retailers now in four bottle sizes, priced as follows:

  • 60ml (2 oz) 7€
  • 250ml (8 oz) 15€
  • 500ml (17 oz) 21.50€
  • 1000ml (34 oz) 34€

Here is a reminder of the MilKit portable tubeless booster. We think it looks pretty impressive. I don’t have an inordinately expensive air compressor for seating tubeless tyres sat at home, do you? If not, this could be a neat solution.

stan’s claim can seals up to 6.5mm even they lie.
not sure if the liquid already dead when I get puncture or else, because I live in place where lowest temperature is 25 degree celcius.
tubeless sucks in hot climate.

I’ve tried Stans, Boyds, Orange Seal, and Finish Line sealants and I’d gladly try Milkit sealant. The only sealant that I haven’t had a problem/puncture is Finish Line (although I know others have had problems). The other sealants have all performed roughly the same (in a road application).

Slime Pro worked well for me.

funny you give them (green points) for lack of ammonia, a common naturally occurring household chemical and yet fail to mention that microfibre pollution is a significant global environmental disaster without any solution in sight…

I like the diagrams for how a syringe works

I am interested in knowing if Milkit actually has a longer life than its competitors? If it truly has a longer life is it based on environment of warmer or cooler climates? The owner mentions that he was riding at Moab and had gotten a flat only to find out that the sealant had dried up and the whole purpose of this invention was to create a longer lasting sealant.
