6600 Series
Performance
Features
• Poppet valves are mated with a solid metal perch that
maintains valve alignment and prevents flow checking.
• Both the coupler's sleeve and the nipple's body are
hardened to make the 6600 Series couplings resistant to
damage from brinelling and mechanical shock.
• The durable-ball-locking mechanism ensures a reliable
connection every time.
• 6600 Series couplings have female pipe and straight thread
end configurations as standard.
• Parker 6600 Series couplings interchange with couplings
meeting ISO 7241-1, Series A.
Applications
Versatile Parker 6600 Series couplings are used in a
wide range of hydraulic applications including construction
equipment, manufacturing machinery, and in-plant systems.
They can be found anywhere the fluid transfer lines need to
be connected and disconnected for operation or maintenance
of equipment. Rugged construction makes the 6600 Series a
good choice for mobile applications including dump trucks,
snow plows, refuse hauling, mining, asphalt paving, truck
trailer connections and many more. In-plant machinery
applications include hydraulic fluid, chemicals and gas
lines for paper mills, steel production, and many varieties
of plant maintenance and production equipment.
Note: Protective dust plugs and caps play a crucial role
in the life of a quick coupling and no purchase of a hydraulic
quick coupling is complete without the selection of an
appropriate dust plug and cap. See pages noted in Table
of Contents for dust plugs and caps for the Parker full
line of hydraulic couplings.
