8.0 TORQUE CHART – METRIC BOLTS
The following chart gives the standard torque setting of the bolts used in this hydraulic kit installation. It is
important to follow the chart when installing bolts and nuts. Failure to do so could result in premature
failure, damage to components, or even serious injury.

8.1 TORQUE CHART – JIC CONNECTIONS
JIC (SAE 37º Flare) Connections are a very common connection in fluid power applications. Both the male
and female fittings have a 37º seat. The seal takes place between the male flare and the female cone seat.
The thread holds the connection mechanically.
