Tubeless Sealant

Peaty’s tubeless sealant is an ammonia-free, non-hazardous, latex-based tubeless tyre compound. Our sealant lasts up to 6 months in the tyre in temperate climates*, won’t ball up in the tyre and is easily washed out with water.

 

Our lightweight formula seals quickly and effectively, while our biodegradable glitter platelets take care of holes and tears up to 6mm. added corrosion inhibitors prevent degradation of tyres and rims.

⚠️ Wait, is that plastic glitter?!

Hell no! No micro-plastics or microfibres here… The platelets in our sealant are BioGlitter made from a special form of cellulose from hardwoods, primarily eucalyptus sourced from responsibly managed and certified plantations operating to PEFC™ www.pefc.org standards. They work like platelets in your blood, building up behind holes to help our fast acting sealant form an even stronger bond with the rubber in your tyre.

🛠️ Key Features:

  • C02 compatible
  • Seals up to 6mm holes
  • Operating pressures: 15 to 120 psi
  • Operating temperature: -20°c to +50°c
  • Seals porous tyres and bead/rim gaps

📝 Recommended Quantities*:

  • Road 30 - 45ml
  • Cyclocross 60 - 75ml
  • 26” MTB 60 - 80ml
  • 27.5” MTB 70 - 90ml
  • 29” MTB 100 - 120ml

*Quantities quoted per tyre. For wider rim / tyre combinations and / or additional puncture protection we recommend adding up to 30ml more sealant to the above quantities

🛠️ Setup Instructions

  1. Shake the packaging vigorously before every use to ensure an even distribution of platelets.

  2. Rinse away any dirt, oil and other sealants from the tyre and dry off completely. See the below FAQ section for more detailed information on this.

  3. Seat both sides of your tyre onto the rim and inflate initially with no sealant, using a track pump, inflator or compressor to pop the tyre bead fully onto the rim. If using a track pump, a good tip is to remove the valve core before inflating as doing so allows a greater volume of air into the tyre and so helping it to seat more easily.

  4. Deflate the tyre fully, taking care to keep the tyre bead fully seated on the rim.

  5. remove the valve core from the valve and Put it in a safe place (you'll need to put it back in shortly!)

  6. with the valve at the three o’clock position, Push the pouch directly onto the valve (120ml Trail Pouch) or use the flexible injector pipe provided (500ml or 1L Workshop Bottle) to inject the desired amount of sealant directly through the de-cored valve.

  7. Re-insert the valve core and re-inflate the tyre to desired pressure.

  8. Wash away any excess sealant that may have found its way to the outside of the tyre or rim with water.

  9. GO RIDE! This will disperse the sealant around the inside of your tyre and rim sealing any small gaps.

🛠️ Peaty's Top Sealing Tips

Make sure you thoroughly clean the inside of your tyres of any dirt, oil and other sealants before you first setup tubeless. New tyres are often coated on the inside with a residual chemicals from the manufacturing process (specifically release agents) which can react with tubeless sealant and cause it to solidify prematurely.

Let the tyre dry fully after cleaning and wipe the tyre with Isopropyl Alcohol or our Disc Brake Cleaner before applying sealant.

Tubeless tyres rely on a thin lining of butyl rubber on the inside of the tyre to hold air (and sealant). Some new tyres (especially very thin / lightweight tyres) can have tiny imperfections in this lining making the tyre slightly porous so it is normal for new tyres to deflate slightly after the first installation.

Porous tyres may also absorb some sealant within the first few riding hours to help seal these tiny holes. In severe cases you may even see this small dots of white fluid coming out of the sidewall of your tyre. This is fairly normal and should seal within 24hrs but if your tyre continually leaks out of the sidewalls then contact your tyre manufacturer as there may be a larger fault with the tyres construction.

It is best to check your sealant levels after two weeks of application and top-up any lost fluid if required.
