Hydraulic Installation
Hose and Fitting Selection Recommendation
Functions must be connected to the HPU manifold using proper
hydraulic hose size and type. Required hose type is SAE 100 R2
or SAE 100 R8. Hose size is determined by flow and run length
between HPU and function.
When ordering, specify that all hoses are flushed, filled with clean
oil and capped at point of purchase. In most conditions, Harken
recommends ISO 46 grade oil*. (See Oil Equivalent Table, pg. 15)
If hoses are shipped, they may not contain oil. Harken can
supply flushed, clean, empty hoses if ordered when purchased.

Hose Shortening
Hydraulic hoses typically shorten 2% to 4% of total length when pressurized. When routing and measuring hose lines, ensure extra hose
length is added to compensate for the hose shortening under pressure.
End Fittings
Hydraulic fittings vary widely. HPU manifold A and B ports are -8 SAE female. P and T ports are -10 SAE female. The case drain is
-8 JIC male. Hose end fittings may be selected to fit existing function fittings, or function fitting may be replaced. Refer to individual
function manuals for specific A&B and drain port sizes.
Fitting Instructions
End fittings must be installed using proper tools by qualified persons. Fittings should be stainless steel whenever possible.
Note: Always ensure pressure rating for selected hose is equal to or greater than 2000 psi/140 bar.
Recommended Hose ID for Hose Lengths Under 40'
CAUTION! Cadmium plated fittings rust in saltwater environment. Replacement costs outweigh initial cost advantages.
