Capula Valve in Hydrogen Refuelling

After hydrogen vehicles refuel, an automatic shut-off valve, called the capula, closes to prevent gas leaks after disconnection.

Using most conventional lubricants can lead to the capula not correctly detaching from filling ports in cars. This can lead to an increased chance of accidents, unexpected breakdowns and emergency maintenance requirements. 

By using leading lubricants on the capula, hydrogen vehicle manufacturers can ensure that the valve will separate safely without repulsion, protecting the dispenser and the vehicle.

Molykote Lubricants for Emergency Detached Capula

Molykote provides high-performance lubricants that can provide:

  • Long term lubrication
  • Reduction of wear and friction
  • Temperature regulation
  • Keeping contaminants away from key parts
  • The improved service life of components
  • Reduced requirements for maintenance

Here we explore the Molykote lubricant that our Molykote representatives have used to successfully ensure the optimal performance of capulas within hydrogen vehicles:

Molykote HP-300

Molykote HP-300 is a fully fluorinated grease that provides outstanding performance in extreme conditions. This lubricant has been successfully used for treating the capula across different automotive manufacturers. It functions optimally in capula applications which commonly operate at -40C temperatures. It is also compatible with EPDM rubbers, and causes no hydrogen embrittlement. In addition, it provides good chemical resistance, oxidative stability and performance across a wide temperature range.
