Technical Information
Fritsche 600-840 bar high-pressure hoses are suitable for grease and central lubrication systems of all conventional lubrication system manufacturers.
The structure of this type of high-pressure hose (600-840 bar) is such that an inner polyamide 6 (PA6) tube is encased and embedded in polyester mesh. The outer polyurethane coat is adhered onto the polyester mesh and the inner tube. Only this structure provides the required high compressive strength to our hose and ensures indispensable safety for assembly.
Of course, the hose is also guaranteed to provide high flexibility.
For many physiological applications, separate requirements often apply, which must be checked case-specifically by the customer.
The responsibility for the implementation, mounting and use of high-pressure hoses is not the responsibility of Fritsche GmbH & Co.KG.
The warranty is limited to the specification of this technical data sheet.
Further warranties will not be accepted.

Our high-pressure hoses play a major role in all systems where maintenance is automated through application of a central lubrication unit. Of course, it is possible to use 600-840 bar high-pressure hoses for manual lubrication aids together with our nipple blocks.
A typical use of these types of hoses is as main lines in central lubrication units. Main lines are defined as the line path from the pump element of the piston pump to the first distribution unit, also referred to as manifold or main distributor.
However, the high-pressure hoses may also be used as secondary lines for the path between main distributor and the downstream secondary distributors, also referred to as sub-distributor.
Due to their excellent flexibility and their extremely hard-wearing surfaces, high-pressure hoses can be used for both manual lubrication and automated central lubrication systems.
For installation, the ends of the 600-840 bar high-pressure hoses are appropriately equipped with screw sleeves and tube studs and prepared for assembly. Apart from conventional box spanners, no other or special tools are required for assembly.
In our capacity as manufacturer, we are obliged to inform our customers that installation of high-pressure hoses and their connection elements must only be performed by appropriately trained qualified personnel.
