ÖldruckMaster für Hydrauliksysteme | SCHAUENBURG Industrietechnik

Controlled pressure relief with the ÖldruckMaster

In agricultural engineering and farming, residual pressure builds up in every hydraulic line sooner or later. Temperature fluctuations, periods of inactivity, and load changes directly affect the hydraulic line. In some cases, it is no longer possible to connect the lines.

We supply OEM partners, resellers, and your business, thereby ensuring greater safety for your equipment.

The ÖldruckMaster enables controlled pressure relief directly at the hydraulic line. No modifications. No interference with the existing hydraulic system. Residual pressure in the hydraulic hose is specifically relieved, allowing for reliable reconnection.

Several models are available for different applications. The ÖldruckMaster is available as a plug, a socket, and for flat-seal couplings. Variants for permanent installation on the tractor are also available. This allows the ÖldruckMaster to be flexibly integrated into existing hydraulic systems.

The use of the ÖldruckMaster ensures that the clutch and hydraulic lines are handled with care. Clearly defined procedures reduce the risk of operating errors and enhance safety. This simplifies service work, maintenance, and daily field operations.

Instructions for using the ÖldruckMaster in hydraulic systems

1. Connect the ÖldruckMaster to the tractor

The ÖldruckMaster gets connected to a free hydraulic coupling on the tractor using the provided plug side. The hydraulic system’s control valve can be single- or double-acting and initially remains in the neutral position.

2. Connect the pressurized hydraulic hose assembly

The pressurized hydraulic hose is connected to the opposite side of the ÖldruckMaster. The connection to the hydraulic line is carried out in the same way as for a conventional coupling, without placing additional strain on the hydraulic system.

3. Trigger a pressure pulse in the hydraulic system

A brief pressure pulse is generated via the tractor’s control valve. This opens the valve in the hydraulic hose connector, allowing the remaining pressure to drain off into the hydraulic system in a controlled manner.

4. Release the pressure in the hydraulic line

Next, set the control valve to the “lower” position. The pressure in the hydraulic line will decrease in a controlled manner. Wait a moment to ensure that the hydraulic line is completely depressurized and the hydraulic system has been relieved of pressure.

5. Disconnect the hydraulic hose safely

Once the pressure has been relieved, the hydraulic hose can be easily disconnected from the hydraulic line. The ÖldruckMaster is then disconnected from the tractor’s hydraulic connection and is immediately ready for its next use in agricultural machinery and farming.

Use in mobile hydraulic applications

Assistance in everyday work

The ÖldruckMaster is used wherever hydraulic hoses are regularly connected to and disconnected from attachments. In mobile hydraulic systems, residual pressure can build up in the hydraulic hose due to changing temperatures, changing loads, or long periods of inactivity. This residual pressure prevents a smooth connection process and, in practice, often leads to increased effort or inappropriate attempts to resolve the issue.

The ÖldruckMaster enables controlled pressure relief directly at the connection point and supports safe and repeatable procedures in daily use. At the same time, it protects the hydraulic system and reduces wear on coupling components.

Application in agricultural technology and mobile machinery

Typical areas of application are found in agriculture. Hydraulic lines are frequently replaced there, for example on tractors with interchangeable implements or in mobile applications outside the workshop. The ÖldruckMaster is used as a portable tool to enable safe pressure relief in hydraulic systems even in the field or on construction sites. This allows coupling operations to be performed without additional tools and without increased physical effort.

ÖldruckMaster plug

Plug under pressure
The ÖldruckMaster plug is designed for applications in which the hydraulic hose remains under residual pressure after disconnection. It enables controlled pressure relief directly at the coupling in the hydraulic system and reduces risks when reconnecting the hydraulic line. This helps to prevent damage to the plug, socket, and seal. Work processes become safer, particularly for mobile hydraulic applications in agricultural engineering and farming.
Additional models, technical specifications, and compatible variants of the ÖldruckMaster plug are available in the e-catalog. You will find a complete overview of standards, sizes, and applications for hydraulic hoses and lines there.

ÖldruckMaster socket

Socket under pressure
The ÖldruckMaster socket is designed for applications involving hydraulic couplings that remain under residual pressure within the hydraulic system. Controlled pressure relief significantly eases the process of safely disconnecting and reconnecting hydraulic systems. This reduces mechanical stress on the coupling and seal, and assists in the safe handling of hydraulic couplings during daily use.
All available models and sizes of the ÖldruckMaster socket are listed in the e-catalog. There you can select the right model for your hydraulic system and request it directly.

ÖldruckMaster fixed mounting

The ÖldruckMaster fixed mounting system is designed for stationary use on agricultural machinery. Thanks to its fixed integration, the tractor is equipped with a designated pressure relief mechanism. Connecting hydraulic lines and hoses with residual pressure can be performed safely. In daily use on tractors and implements, the fixed mounting system supports reliable and systematic operation of the hydraulic system.
Technical specifications for the ÖldruckMaster fixed-mount version, including size and connection details, are listed in the e-catalog. You will find further information there regarding the technical specifications for your application.

ÖldruckMaster FlatFace

The ÖldruckMaster FlatFace is designed for flat-face hydraulic couplings in accordance with ISO 16028. Even a small amount of residual pressure in a hydraulic line or hose can hinder the coupling process. The ÖldruckMaster FlatFace enables targeted pressure relief directly at the FlatFace plug and ensures clean, controlled operations in the hydraulic system. It is especially suitable for mobile applications in agriculture with high sealing requirements.
Technical information on the ÖldruckMaster FlatFace, including the ISO 16028 standard, size, and connection specifications, is compiled in the e-catalog and helps with clear technical identification.

ÖldruckMaster FlatFace fixed mounting

The ÖldruckMaster FlatFace fixed mounting is designed for flat-face hydraulic couplings that require a permanent pressure relief solution. Thanks to its fixed integration onto the tractor, it provides a defined pressure relief option for flat-face connections on hydraulic lines and hoses. This supports clean coupling processes and reduces the risk of leaks in regularly used agricultural machinery and equipment.
All technical specifications for the ÖldruckMaster FlatFace fixed mounting system, including size and connection details for hydraulic lines and hydraulic systems, can be found in the e-catalog. There, you can select the appropriate model and request it directly.

Additional components for service and installation

In addition to the ÖldruckMaster, a range of additional equipment is available to ensure safe and organized handling of hydraulic hoses. This includes marking solutions such as the Marking Box, additional connectors, pipe fittings, and supplementary components for service and installation. The products are designed for use in mobile hydraulic systems and support clearly defined, practical workflows, particularly in the daily use of agricultural machinery and farming.

All available components for use on hydraulic lines are listed in the e-catalog along with their corresponding technical specifications.
