JOES NO-FLATS Yellow Sealant in a 20-litre workshop bulk pack is the trade-size solution for busy bike shops that service tubeless and tube-type tyres at volume — keeping costs down and shelves stocked.

  • Seals punctures instantly in inner tubes and tubeless tyres
  • 20L bulk refill — decant into smaller bottles as needed
  • Works on thorn holes, small cuts and pinch-type perforations
  • Safe on alloy and carbon rims — non-corrosive formula

The Yellow Sealant's fast-acting formula activates on contact with air, forming a flexible plug at the puncture site. Effective in inner tubes as a preventative or reactive solution, and in tubeless setups as a standard sealant top-up. Suitable across road, gravel and mountain bike applications.

Compatible with all standard Presta and Schrader valve tube types, and tubeless tyre and rim combinations. Shake well before use.
