Torque - Standard torque data for hydraulics

D150C
NOTICE: Hydraulic connections require a minimum assembly torque in order to provide zero leakage at rated pres-
sure with adequate fatigue resistance. Too much torque on a hydraulic connection can lead to leakage or failure.
NOTICE: There are several different kinds of parallel thread ports, including those using metric threads, inch threads,
and British Standard Pipe Parallel (BSPP) threads. None of these port systems are interchangeable, and using the
wrong connector in a port will not provide an adequate seal, even if it is possible to install the part.
NOTE: Hand install and hand tighten all connections before using tools to set the torque. This will reduce the possi-
bility of thread damage.
