1

Unscrew pressure line connection (1a) from affected component part (e.g. air suspension bellows) using   socket wrench socket.

 Use suitable open end wrench bit in combination with  socket wrench socket.

2

Cut pressure line (4) using an   isolating blade to a suitable length.

 Special care must be taken to ensure that the cut is exactly at right angles to the pressure line (4).
Otherwise the pressure line (4) may suffer more leaks.

3

Plug in cut-off pressure line (4) up to end stop or at least 19.5 mm into pressure line connector (3).

 If necessary, mark the pressure line (4) at 19.5 mm with a felt-tip pen beforehand.

4

Pull back pressure line (4) slightly, to enable the surrounding retaining edges inside the clamping ring (1b) to engage in the outer surface of the pressure line (4).

5

Cut repair line (2) so that the original length and form (straight end or 90° curved section) of the pressure line (4) to be repaired is reached again.

 When cutting off the repair line (2) take into account the insertion depths in the repair screwed connection (1) and pressure line connector (3).
Leaks can occur otherwise.

 Special care must be taken to ensure that the cut is exactly at right angles to the repair line (2).
Otherwise renewed leaks may occur.

6

Insert repair line (2) into pressure line connector (3) up to end stop or to at least 19.5 mm.

 If necessary, mark the repair line (2) at 19.5 mm with a felt-tip pen beforehand.

7

Pull back repair line (2) slightly, to enable the surrounding retaining edges inside the clamping ring (1b) to engage in the outer surface of the repair line (2).

8

Screw repair threaded connection (1) into affected component part using   socket wrench socket.       

 Use suitable open end wrench bit in combination with  socket wrench socket.

9

Pull plastic guard (1c) out of repair connection (1).

10

Insert repair line (2) into repair threaded connection (1) up to end stop or to at least to 19.5 mm.

 If necessary, mark the repair line (2) at 19.5 mm with a felt-tip pen beforehand.

11

Pull back repair line (2) slightly, to enable the surrounding retaining edges inside the clamping ring (1b) to engage in the outer surface of the repair line (2).

12

Route pressure line (4) on vehicle.

 When pulling in or routing the line it should be noted that, after fastening, the lines cannot be twisted anymore.

13

Secure pressure line connector (3) at suitable position on vehicle using cable tie.

 To avoid any chafing or noise generation.
