Component Identification:

In the event of damage to the pressure line connections (1a) and pressure lines (4) a pressure line connector (3) or repair screwed connection (1) can be attached.

Attention is to be paid to carrying out the repair carefully in order to avoid renewed leakage.

Shown on air suspension strut
1 Remove pressure line connection (1a) from the component in question (e.g.air suspension strut) and cut off pressure line (4) to a suitable length using a knife.

Special care must be taken to ensure that the cut is exactly at a right angle to the pressure line (4).

2 Insert the cutoff pressure line (4) up to the stop or 19.5 mm into the pressure line connector (3).
3 Cut the repair line (2) so as to obtain the original length and shape (straight end or 90 degrees arc) of the line.

Do not kink repair line (2). When cutting off the repair line (2) take into account the insertion depths in the repair screwed connection (1) and pressure line connector (3).

Repair lines (2) supplied from through the spare parts channels, each repair (2), with one straight and one bent end.
4 Insert the repair line (2) up to the stop or to a depth of 19.5 mm in the pressure line connector (3).
5 Screw the repair bolted connection (1) into the component in question.
6 Pull plastic guard (1c) out of repair connection (1).
7 Insert the repair line (2) into the repair bolted connection (1) up to the stop or to a depth of 19.5 mm.

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

After insertion the pull back the pressure line (4) slightly so that the circumferential retaining edges inside the clamping ring (1b) engage in the outer surface of the line.

When pulling in or routing the pressure line (4), it should be ensured that, after fastening, the pressure line (4) cannot be twisted anymore. The pressure line connectors (3) should be attached to a suitable point on the vehicle with cable ties so that chafing of the pressure line (4) or noise development is prevented.

If bubbles form at the repair point after a leak test with leak detecting spray, it must be checked whether the pressure line (4) is inserted as far as the stop. If bubbles continue to form nevertheless, then the pressure line connector (3) may be defective and a new pressure line connector (3) or a new repair bolted connection (1) should be used.
