Suitable for demanding lubrication hose assemblies, e.g. central lubrication circuits in machinery and other applications requiring lubrication. The hose is easy to cut (e.g. with brake pipe pliers 088520 02) and connections are easy to make. The inner tube of the high-pressure hose is made of polyamide-6 (PA6). The tube is encased and vulcanised into a reinforcing polyester braid.

5973 101 912 – 5973 101 922
Threaded sleeves 5973 101 912 and 5973 101 920 have a left-hand coarse thread on the other side. The sleeve is first rolled onto the hose (approx. to the middle).
Attach a screw-type connector inside the sleeve and hose.
Finally, use a wrench to tighten the connection. The connector pushes the hose’s outer edge inside the sleeve and inner edge against the connector.
This way the connection remains sturdy and secure.
The left-hand coarse thread on the sleeve prevents the hose from detaching from the sleeve when the connector is attached to the sleeve.
