When must a flexible (rubber) hose connector used in the piping system of a bobtail be replaced?

The recommended replacement interval for a flexible (rubber) hose connector used in the piping system of a bobtail is every 10 years. This guideline is essential for ensuring the safety and reliability of the gas delivery system. Over time, rubber hoses can degrade due to exposure to environmental factors, such as ozone, heat, and pressure fluctuations. These factors can lead to cracks and material failures, increasing the risk of leaks and potential hazards.

Regularly replacing these connectors helps to mitigate these risks, ensuring that the hose maintains its integrity and function over its service life. Following the manufacturer's recommendations and industry standards is crucial for maintaining safety compliance in liquefied petroleum gas systems. In this context, adhering to the 10-year replacement guideline is vital to ensuring safe and effective operations in the use of bobtail vehicles for gas delivery.
