The bike tire sealant is an excellent solution for punctures. It is easy to use and does not require any special knowledge, just follow the instructions. According to the manufacturers, the anti-piercing fluid is able to close a gap that is up to 6 millimeters in size. Although practice shows slightly different results. Let’s consider how to properly seal punctures, and what tire puncture sealant for tubeless bicycle tires is better.

Which Sealant To Use?

As trite logic and sealant manufacturers suggest, there is no limit to what sealant to use with tubeless tires. It only makes sense to think about it when the manufacturer of the tire or rim tape explicitly states that only a certain sealant should be used with their products. However, we have prepared a list of the best products, which you can buy in every bike shop!

TOP-3 Sealants

Tubeless tire sealant has gained great popularity because of its availability, effectiveness, and ease of use. It is enough to follow a little instruction on how to use it, then the product itself will seal the puncture on the tubeless tire of the bicycle even without your participation.

But which company to choose? It is easy to make a wrong choice and buy a low-quality anti-tear fluid. Let’s consider a list of the best sealants that have performed well in tests.

Orange Seal

It costs $15 for a 227ml volume or $75 per liter. It is a latex solution that contains solids of various sizes. The test found that sealing required two turns of the wheel, and the treated tire held 2.8 bars of pressure. During a double puncture made from different sides, Orange Seal was able to cope with the task and seal the punctures made. The kit comes with a special tube, which facilitates the adding sealant to the tubeless bike tires process. The disadvantages are high cost and a short operating time – up to 45 days.

Caffelatex by Effetto Mariposa

The presented product has a small price, especially in comparison with the Orange Seal. 29 dollars for one liter. How does tire sealant work? It has a foamy structure, this allows the substance to spread well on the tire. The composition includes solid particles that fill in the holes. This sealant was able to make up a puncture made with a screwdriver in a short period of time.

Continental RevoSealant

The price for 1 liter of RevoSealant is approximately $33.87. Developed specifically for Conti tires. But, experimentation showed that the tool copes well with other brands, for example, Maxxis. It is a latex sealing compound, which also contains solid particles that perfectly seal cracks on the outside of the tire. A puncture made with a screwdriver was fixed after a couple of turns of the wheel.

How To Use Tire Sealant?

Initially, keep a few basic rules in mind:

  • The wheel must be inflated. Remember – the substance penetrates because of the difference in pressure (inside and outside).
  • If you hear a quiet hissing noise coming from the punctured wheel while cycling after pouring the sealant, then continue riding without paying attention. The puncture will fill with the anti-piercing fluid.
  • Experts do not advise the use of automotive sealants. They explain that sealing tubeless tires with the car sealant is ineffective – the puncture will remain.

Any tire sealant comes with the manufacturer’s instructions, which describe the procedure in detail. Then, how to add sealant to tubeless tires? For most products the steps are as follows:

  1. Remove the wheel from the rim. Remove the object that caused the puncture of the rubber: usually, it is a sharp wire, a nail. If it is in the tire, you will have to use pliers to extract it.
  2. Remove all the air out of the tire. Unfold the tire so that the puncture place was in a convenient position.
  3. Does tire sealant work in winter? Yes, however, you need to warm up the sealant bottle a little. Do not use an open flame for this purpose, it is better to warm up the sealant in your hands.
  4. Remove the spool. Install the tip of the cylinder or the tube that comes with the kit for sealant, on the valve of the wheel, fix it as securely as possible.
  5. Fill the tubeless tire with sealant by pushing on the can valve. The latter should only be placed in an upright position. The question arises: how much sealant per tire? It is not that complicated! Let us explain the point. First of all, the amount depends on the inside area, and this often depends on the diameter, height, and width of the tire. Our goal is to have enough sealant to cover the entire tire from the inside and some left to cope with punctures. So there is a certain minimum, which can be recommended, and the maximum is limited only by our adequacy and willingness to carry extra fluid in the wheel. If you pour too little, it may simply not be enough to seal the puncture. If you pour too much, the only significant problem will be the extra weight that will be bubbling around inside the tire, negating the weight gain. The estimations are further: 1 inch is 60 ml; 2 inches is 80 ml; 2.5 inches is 90 ml; 3 inches – 100 ml; 4 inches – 120 ml.
  6. After the tire has been shaped, disconnect the can from the valve. Check the tire pressure and, if necessary, deflate or inflate the tire with a compressor. Now you know how to get a tubeless tire to seal.

How Often Do You Need To Add Tire Sealant To Bike Tires?

It all depends on the conditions of use. It retains better in the cooler, and logically worse in the hotter conditions. Also, don’t forget that when you puncture it, some volume comes out. For all these reasons, it is recommended to either change all the sealant in the tubeless tires every six months, or, if conditions are good and the punctures were minimal, just add one-third of the required volume. Or if you feel while riding that the pressure in the tire is low- obvious sign it’s time to add sealant to the tubeless tire.
