For limit areas, please contact us. It is often enough, to select a pipeline which is one size larger.

Attention!

An underdimensioned prefill valve and/or an underdimensioned line leads to gas leaks from the hydraulic fluid with corresponding consequences and often to long-term damage at the cylinder seals.
