Designed for mobile air conditioning and refrigerant applications, this carbon steel male coupling half from the Eaton Aeroquip Hansen 5400 Series connects via a thread-to-connect mechanism with a 5/8" UNF male end and a 1/2" UNF female end. The poppet-style, two-way valve design allows quick connection and disconnection without special tools, supporting a rated flow of 2 gallons per minute.
The Danfoss / Eaton Male Coupling Half uses a neoprene seal and exceeds ISO 16028 operating pressure requirements, making it a reliable choice for refrigerant handling in mobile equipment. Manufactured in France under Eaton's Aeroquip brand, this male half pairs within the Hansen 5400 Series quick disconnect coupling system.

Will this Eaton coupling work with my mobile AC unit?

Designed for mobile air conditioning and refrigerant applications, this Danfoss/Eaton coupling half should be suitable.
Question by: Daryl G on Jun 7, 2025, 3:53 PM
got a mobile A/C refrigerant setup, is this the kind of quick disconnect that’ll hook up without any special tools?
Answer by: Customer Support on Jun 9, 2025, 8:39 AM
Built for mobile air conditioning and refrigerant work, it is a quick disconnect coupling that connects and disconnects without special tools. It uses a thread-to-connect setup with UNF threads.
Question by: Steve B on Sep 21, 2025, 1:16 PM
does this thing work for mobile AC systems, or is it more of a stationary setup kind of deal
Answer by: Customer Support on Sep 23, 2025, 12:46 PM
Mobile air conditioning is exactly what this coupling half is built around. It handles refrigerant lines in on-equipment AC systems, so anything running climate control on machinery or vehicles is right in its wheelhouse. The 2-way valve design and neoprene seals are well suited to that kind of refrigerant service.

got a 5400-s2-4 on the bench, is this the male half and what’s it meant to hook up to?
Answer by: Customer Support on Nov 12, 2025, 7:56 PM
It’s the male coupling half in the Hansen 5400 Series quick disconnect line, set up as a 2 way poppet valve assembly. The application is mobile air conditioning and refrigerant service where you want a quick connect and disconnect without special tools.

reckon this'll work for mobile AC hookups like on a tractor?
Answer by: Customer Support on Mar 23, 2026, 6:49 AM
These Danfoss/Eaton couplings are indeed used for mobile air conditioning and refrigerant applications.
Question by: Lee S on May 16, 2025, 4:14 PM
what's the seal material on this coupling half? trying to figure out if it'll hold up with refrigerant lines on mobile AC equipment
Answer by: Customer Support on May 18, 2025, 2:58 PM
Neoprene seals are used in this coupling, which lines up well with mobile air conditioning and refrigerant applications. That combination is what this part was built around, so you're in the right territory for that kind of work.
