Which statement best describes a drip-tight seal in gas connections?

• A. A loose but water-resistant seal.
• B. A seal that allows minor leaks to vent.
• C. A seal that is installed only at outdoor joints.
• D. A secure, leak-tight connection at appliance connectors and piping joints.

Answer: (D)

A drip-tight seal means there is no gas leakage at the joints; the connection is totally leak-proof under the expected operating conditions. This is why the statement describing a secure, leak-tight connection at appliance connectors and piping joints is the best answer—it captures the essence of drip-tight: no leaks from the joints where the gas lines meet appliances or other piping. In practice, these joints are assembled and then tested to ensure they hold under pressure, confirming that gas cannot escape into the surroundings. The other descriptions imply leaks, venting, or restriction to outdoor joints, which do not meet the requirement of being leak-tight.
