The consistently developed and enhanced STAUFF Hydraulic Accessories product range contains of well thought-out and sophisticated components suited to meet or exceed the increasing requirements of designing and building tanks, reservoirs, power packs and gear boxes for industrial and mobile hydraulic applications.

Whether you require visual or visual/electrical fluid level and temperature indicators, tank filler breathers in a variety of designs made of plastic or metal, or desiccant air breathers to protect your reservoir from contamination and moisture: STAUFF Hydraulic Accessories will provide you with the product you need.


The programme is completed by suction strainers and Diffusers that are positioned within the reservoir and connected directly to the suction and return lines.

For challenging applications, STAUFF is able to provide technically modified product versions, which, for example, convince with their outstanding resistance to external influences (such as high or low temperatures, aggressive media or UV exposure) or their compact and light-weight design.


STAUFF guarantees prompt service, even for customised solutions according to customer’s  specifications or based on our in-house development.

Characteristics

The STAUFF Level-Temperature Switches (SLTS Series) are unique in their design and modularity. One of the greatest advantages is the ability of the end-user to adjust the switching level. The internal support wire carrying the level and temperature switches makes it a simple and quick job to change the level switch position.

  • Either 1 or 2 level contacts available

  • 1 integrated temperature switch (optional)

  • Standard electrical function:
