24 inches

36 inches

The maximum length of hoses that can be installed in CNG systems is 36 inches. This specification is important for ensuring both safety and efficiency in the operation of CNG fueling systems. Shorter hoses reduce the potential for leaks and minimize the risk of accidents that can occur if hoses become compromised. Additionally, maintaining a standard length allows for easier handling and reduces tripping hazards for operators and service personnel.

In this context, the choice of 36 inches aligns with industry safety standards designed to control the integrity and flow of the compressed natural gas, ensuring that hoses can adequately withstand the pressure and handling they will encounter during use. By adhering to this guideline, operators can maintain the reliability of their systems and protect both equipment and personnel.
