The coupling adaptor, for connection to individual pressurised gas container, includes a cylindrical body containing a check valve which retains the pressurised gas. The body is integrally joined to a housing tied to the container. The cylindrical body has two grooves on its surface and on each groove O-ring is seated. An interface passage is formed between two Orings and through the passage pressurised gas moves past the check valve to the pressure regulator. The presence of the O-rings guarantees a balanced gas pressure, maintaining the parts of the coupling adaptor joined. |
