What is the maximum length permitted for a corrugated metal connector?

The maximum length permitted for a corrugated metal connector is established based on safety standards and regulations for gas installations. A length of 6 feet is deemed adequate to ensure proper functioning, maintain flexibility in installation, and facilitate safe connections. This limit helps to minimize stress on the connector and surrounding equipment, reducing the risk of leaks or failures that could arise from excessive length.

By adhering to the 6-foot specification, technicians can ensure they are following best practices and regulatory requirements, which are crucial for maintaining safe working conditions in gas systems. The other lengths are either too short or too long, potentially leading to complications in installation or increased risk of failure.
