What type of CGA fitting does propane have?

• A. 510
• B. 400
• C. 320
• D. 540

Answer: (A)

Gas delivery connections are standardized by CGA numbers, and each gas type uses a specific outlet connection that matches only the appropriate regulator. Propane cylinders use the CGA 510 outlet, so the regulator and hose designed for propane will have a 510 connection that threads and seals correctly with the cylinder valve. Using a different CGA size would either not fit or leak, which is unsafe. The other numbers correspond to different gases or equipment configurations, so they don’t apply to propane. In practice, always match the regulator’s CGA fitting to the propane cylinder’s valve outlet to ensure a proper seal and safe operation.
