TODO PTC Safety Pressure Tight Cap


Designed in close collaboration with leading gas and oil companies, the TODO Safety Pressure Tight Cap is designed with the needs of businesses in mind. Containment security and operational safety are two of the biggest concerns in the industry and both of these are assured with the TODO Safety Pressure Tight Cap.

Companies are assured better safety credentials and operational benefits when using the TODO Safety Pressure Tight Cap. No other existing closure technology comes close.

The cap will sense when the event of an upstream closure leakage is possible and will hold any pressure necessary until the problem is resolved. If the cap should be removed for any reason, it will quickly decrease the pressure to avoid forceful transfer of the media. This will improve profits and prevent operators from coming to harm.


  • Pressure indicator alerts the operator to pressure above 1.0 bar behind the cap & possible failure of upstream closure
  • Automatic Depressurisation reduces any static pressure upstream of the cap upon operation. Any other sealing cap or flange may allow removal under pressure with potentially serious consequences for the operator
  • Removes the possibility of disconnecting the cap whilst under pressure
  • Customs / tamper seal feature, the cap operating mechanism will accept all commonly used wire and plastic custom seals
  • Automatic locking (with manual locking available), in either direction but requires a deliberate action to disconnect.
  • The PTC is certified as a full second or third closure depending on the application. The cap can be used to replace other closure methods such as valves.
  • Manually lockable using a padlock.
