Hydraulic Hose and Fitting Torque Specifications
Your machine is equipped with either 37° flared fittings and hose ends OR Parker Seal-Lok® fittings and
hose ends. Machines that utilize Parker Seal-Lok® hoses and fittings require that the fittings and hose
ends be torqued to specification when they are removed and installed or when new hoses or fittings are
installed. Machines equipped with 37° flared fittings and hose ends do not need to be torqued to these
specifications.
Torque Procedure
1 Replace the O-ring. The O-ring must be
replaced anytime the seal has been broken.
The O-ring cannot be re-used if the fitting or
hose end has been tightened beyond finger
tight.
The O-rings used in the Parker
Seal Lok® fittings and hose ends
are a custom-size O-ring. They
are not a standard SAE size
O-ring. They are available in the
O-ring field service kit (Genie part
number 49612).
