5500 Series Self-Sealing
Brass Coupling
Parker’s 5500 Self-Sealing Brass Couplings are used
in fluid-transfer applications for easy maintenance on
refrigeration and air conditioning systems. Applications
can also include marine refrigeration and air condition-
ing systems, along with split refrigeration and split
beverage systems.
Application
• Portable split-system air conditioners
• Split refrigeration systems
• Marine refrigeration systems
• Refrigerated dry cleaning systems
• Beverage systems
Base Product Part Number
5502 Male coupling half
5505 Female coupling half
Features and Benefits
• Self-sealing upon disconnection maintains
minimum inclusion of air and loss of fluid.
• Brass coupling provides corrosion resistance.
• Final metal-to-metal seal provides low leakage.
Technical Information
Corrosion Resistant
Brass body and copper
connections make corrosion-
related problems almost non-
existent.
Efficient
Full flow/low pressure
drop design helps improve
equipment efficiencies.
Superior Sealing
Unique self-sealing valving prevents
refrigerant loss when disconnected.
Metal-to-metal final seal virtually
eliminates refrigerant loss when
connected.
Reliable
Stringent design standards, backed
by years of experience, a wide range
of existing coupling applications, and
extensive testing under extreme
operating conditions, provide you
with the assurance that the product
will perform as specified.
Easy to Connect/
Disconnect
Thread-together design
allows easy connection and
disconnection while under
system pressure.
Low Air Inclusion
and Refrigerant Loss
Valving is designed for low air
inclusion and minimal refrigerant loss
during connection and disconnection.
Simplified Installation
Copper sweat connections simplify the
factory installation process (eliminating
the need for flux and flux residue clean
up), saving you time and money.
• Copper-sweat connections provide basic ends
for brazing and eliminate the need for flux,
simplifying the installation process.
• Panel mounting options are available for the
unique needs of a unit.
