does this coupling work with refrigerant lines on mobile AC systems, or is it more of a stationary setup thing
Answer by: Customer Support on Aug 21, 2025, 11:21 AM
Mobile air conditioning is exactly what this coupling is built around. The 5400-S5-8 is a female half from the Hansen 500 Series and is made specifically for mobile AC and refrigerant applications. The carbon steel body with neoprene seals holds up in those kinds of environments, and the thread-to-connect design means you get a reliable seal without needing any special tools to make or break the connection.

Match-up is straightforward here. The supplier part number for this female half is 5400-S5-8, and it is an Eaton Aeroquip Hansen 500 Series quick disconnect coupling socket, so it lines up as the correct female half when you are replacing the same part number.
