Hydraulic Accessories
Harken offers a complete range of high-quality kits and components for the 
professional installation, service, and maintenance of your hydraulic system.
Filters
Filtration is essential to the health and longevity of your hydraulic system. Harken 
recommends the 40-micron suction/return filter between the reservoir and the pump 
as well as an extremely fine 3-micron filter between the pump and the valves. The 40-micron 
filter has an anodized aluminum body with a removable, cleanable, and replaceable sintered 
bronze element. The high pressure 3-micron filter is made from electropolished 17-4 PH 
stainless steel or titanium. It has a replaceable paper element and can handle pressure up to 
10,000 psi. -4SAE ports allow the high-pressure filter to accept any combination of fittings 
and adapters. 
Pressure Transducers
Pressure transducers use the onboard computer to convert hydraulic pressures of 
up to 10,000 psi into tons or other load units. Standard lightweight versions and 
super lightweight Grand Prix versions are available. Contact Harken for availability 
and options.
Seal Kits
Seal kits are available for all valves, cylinders, and pumps. Kits include all normal wear items 
such as O-rings, seals, and nylon tip set screws. 
Repair Kits
Repair kits are available for all valves, cylinders, and pumps. They include everything 
in the seal kit with the addition of select machined components that may require 
occasional replacement. 
HAWE Tool
The HAWE tool is used for removing and reinstalling the check valves included in valve and 
pump repair kits.
Hydraulic Oil
Our hydraulic oil was chosen specifically for Harken high-pressure hydraulic systems. 
Its moisture-resistant formula features unique anti-wear additives that inhibit corrosion and 
provide high levels of thermal and oxidation stability to enhance lubricant 
performance and extend equipment life.
