What is a crucial characteristic of the CNG service hose?

A crucial characteristic of a CNG service hose is its capability to withstand the specific conditions associated with compressed natural gas service. The correct answer relates to its resistance to UV radiation. This is vital because hoses exposed to sunlight and outdoor conditions can degrade over time due to ultraviolet rays, which can lead to leaks or failures in the hose.

CNG service hoses are typically made of materials designed to resist such degradation, ensuring they maintain their structural integrity and performance over time. Hoses that lack UV resistance would pose significant safety and reliability issues in outdoor installations.

While other characteristics, such as flexibility for handling, resistance to extreme temperatures, and electrical conductivity might be relevant in specific contexts, the primary focus in this question revolves around the need for the hose to withstand environmental factors like UV radiation to ensure safety and longevity in service.
