the groove, then press them into the ﬁnal position by using

a soft piece of wood (steadily pressing)

Caution:

The seal must not be damaged

11 Apply the other seals accordingly. Then check the seals

visually. They must be placed evenly in their grooves and

must not be damaged.

12 Grease the ball socket with Vaseline

13 Assemble the ﬁtting again, tighten hexagon screws with a

max. torque of 60 Nm

14 Check the ball for tight movement. At ﬁrst, the ball can only

be moved with a longer lever in mounted condition or when

held in a bench vice.

Only use suitable seal rings (standard: PTFE with carbon and

graphite; alternative: PTFE). Make sure that the seal rings are

not damaged. Damaged rings will cause leakage.
