Pigtail connectors are not used with what type of group?

• A. Line pressure, second stage, and adjustable high-pressure
• B. Residential appliance group
• C. Industrial process gas group
• D. Laboratory gas group

Answer: (A)

Pigtail connectors are designed for delivering gas at low, post-regulation pressures. They’re short, flexible connections used to carry gas from a regulator to a device or appliance that operates at a reduced, safe pressure. Because line pressure, second-stage regulation, and adjustable high-pressure service involve much higher inlet pressures, pigtail connectors aren’t rated or suitable for those contexts. Using them in high-pressure service could lead to hose or fitting failure and leaks. That’s why pigtails aren’t used with line pressure, second stage, or adjustable high-pressure groups, while they are appropriate for low-pressure residential appliance, laboratory, and certain industrial process gas applications where the pressure has already been reduced to safe levels.
