Non-corrosive and hygienic, inside and outside

Hygiene, corrosion resistance and good cleanability are the most important requirements for production facilities in the food industry. The high-quality connections of the Eisele INOXLINE are manufactured from premium non-corrosive and acid-proof stainless steel. All parts are completely cleanable and especially suitable for hygiene-sensitive applications. The stainless steel connections of the 3600 and 3800 series are designed for use with liquid media and are easy to clean, also from the inside. For the supply of compressed air the Eisele BASICLINE offers the largest available assortment of push-in connectors, threaded connections and accessories. The stainless steel MULTILINE opens up entirely new possibilities for modular system concepts. This modular system for multiple connectors enables the reliable, efficient and compact connection of single components or complete assemblies in one simple step by means of a single connector for all media.

Case studies

Eisele MULTILINE multiple connectors in the food production industry

ALPMA Alpenland Maschinenbau GmbH in Rott am Inn delivers its custom machines for cheese production throughout the world. Eisele helped ALPMA to optimise pneumatic connectors and to improve their hygiene, handling and operational reliability.


„Eisele was able to offer a custom solution with a good cost-effectiveness ratio for our area of application.“

Jürgen Osiander, Head of Development and Design at ALPMA.

The challenge

ALPMA was in search of a better connecting option for the exchangeable format sets of a cutting machine for cutting cheese into portions. Previously, up to four pneumatic connections were connected by single coded connectors that easily became entangled and were not entirely non-interchangeable. The new solution required the following features:

- Hygienic design
- Reliable sealing of both connection sides in open state
- Prevention of incorrect connections
- Robust and user-friendly design

The solution

Eisele developed a custom version of the MULTILINE stainless steel multiple connectors. They bundle the pneumatic connections in one connector. The multiple connectors have separate coding pins. They can be connected in only one position, therefore preventing incorrect connections. The connector is locked by means of the format set and not by the connector itself. Eisele developed this custom solution especially for ALPMA.

The product

The multiple and multi-media connectors of Eisele’s MULTILINE provide connections for combining compressed air, vacuum, gases, coolant, liquids, electrical wiring and electronics in one connector body. In addition to combined concepts, complete solutions are also possible for electrical and electronic connections. For use in food processing, all parts are manufactured from stainless steel and the seals are fully FDA-compliant.
