Parker’s 5400 self-sealing steel couplings
are used in uid-transfer applications for
easy maintenance on refrigeration and air
conditioning systems. The couplings also
allow for pre-charging of units for easy
installation. Applications can include
marine refrigeration and air condition-
ing systems, along with cryogenic units.
Applications
 General fluid-transfer applications
 Marine refrigerant and air conditioning
systems
 Cryogenic systems
Base Product Part Number
 5400-S2 Male coupling half
 5400-S5 Female coupling half
Features and Benefits
 Self-sealing upon disconnection main-
tains
minimum air inclusion and fluid loss.
