Register and access more than 75 000 products
Flexible hose for central lubrication, circuits and individual applications.
Ideal for demanding high-pressure applications.
Easy cutting and connection.
- Cutting with e.g. 088520 02 cutting pliers
- For connecting, use e.g. 12-mm and 10-mm wrenches (071330110, 071330112)
High pressure hose (280/840 bar) structure:
- The interior polyamide-6 (PA6) tube is enclosed and vulcanized in polyester mesh.
- Reinforcement: polyester
- The exterior polyurethane layer is attached to the polyester mesh and the interior tube.
- Halogen-free pursuant to DIN VDE 0472-815
This structure gives the hose the required high compressive strength and ensures that the product is very robust and ideal for the intended applications.
Heat resistance: –40°...+80°C.
- For pumped substances, “grease, corrosion preventing agents”: max. +70°C.
Full tolerance.
- Inner diameter, Ø 3.9–4.1 mm
- Outer diameter, Ø 8.5–8.75
Coil length 50 m.

Do not use the hose with threaded sleeves and screw-type connectors other than those specified.
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.
