Reasons for bad sealing of hose junctions:
•
missing O-rings or sealings;
•
damaged or poorly inserted sealings;
•
dry or re-formed sealing or. O-ring;
•
unsuitable joints;

In the case of bad sealing or leaking:

grease it and reassemble the joint.

Use only non-mineral grease (bio-grease) for greasing.
