Hydraulic Reservoirs
Harken offers pressurized composite reservoirs and vented 
blow-molded reservoirs for manual hydraulic systems. 
Pressurized Reservoirs 
All Harken pressurized reservoirs have translucent sections in the 
reservoir walls, making it easy to monitor oil levels. Pressurized 
reservoirs require very little maintenance and are cleaner than those 
that use ambient air pressure. They can be installed in the bilge rather 
than at pump level to provide a low center of gravity. 
Grand-Prix Pressurized Reservoirs 
Harken offers Grand-Prix pressurized reservoirs to suit any 
Grand Prix need. They are among the lightest in existence. 
Reservoirs can be customizable to whatever application is required. 
One-way return-line check valves, supply-line shutoff valves, and high-
quality regulators are available to meet specific needs. Custom sizes and 
configurations are available. Contact Harken. 
Vented Reservoirs 
Harken offers 2- and 4-liter blow-molded reservoirs for standard 
installations. Reservoirs feature a vented cap to stabilize tank pressure 
and prevent leaks. Translucent materials allow oil levels to be easily 
monitored. 10 mm (3/8") hose barbs come standard for supply and return 
hoses.

Pump Handles
Standard round-tipped handles are made of knurled 6061-
T6 hardcoat-anodized aluminum and fit standard HYPM1 
and HYMP2 pumps. Grand Prix versions are available in 
carbon fiber. An optional square-tipped style allows the 
handle to be rocked 5 degrees laterally from the pumping 
direction to store against the cockpit wall.
