3.3 Sealing ring variants
Sealing rings of different materials are used for sealing
on the pressure regulating valve block (Fig. 2) and sole-
noid valve block (Fig. 3). The correct tightening torque
must be used based on the material of the sealing ring
(fiber or copper); otherwise, the joint will not be tight
or the sealing ring will be damaged. Fiber sealing rings
or copper sealing rings were used at the following loca-
tions (see arrows).

i Always use new sealing rings when replacing com-
ponents. The new sealing rings must be made from
the same material as the previously installed sealing
rings. Otherwise, a tight connection cannot be
assured.
Use the following tightening torques based on the mate-
rial of the sealing ring:
