Parker’s 5500 self-sealing brass cou-
plings allow for pre-charging of AC and
heat pump systems. The couplings pro-
vide for easy maintenance and installa-
tion on refrigeration and air conditioning
systems. Applications can also include
marine refrigeration and air conditioning
systems, split refrigeration, and portable
cooling solutions.

Features and Benefits
Self-sealing upon disconnection main-
tains minimum air inclusion and fluid loss.
Corrosion Resistant
Brass body and copper
connections make corrosion-
related problems almost
non-existent.
Efficient
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 elimi-
nates 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
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.
Brass coupling provides corrosion
resistance.
Final metal-to-metal seal prevents refrig-
erant loss.
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.
