We offer a wide range of Cejn couplings for both compressed air and liquids. Cejn is renowned for its high product quality and innovative approach to safe and efficient connections in industrial processes. Our range includes both Cejn eSafe quick couplings and spill-free couplings for fluids, each designed to meet the requirements of the food, pharmaceutical and process industries.  

Cejn couplings are distinguished by their user-friendly design and robust construction. With a focus on both work safety and process optimisation, they enable quick and problem-free connection and disconnection, regardless of whether you are working with compressed air or liquids. 

Cejn couplings are widely used in industries where reliability and operational safety are key. In the food industry, they ensure hygienic fluid handling and safe connection of compressed air systems. In the pharmaceutical sector, the couplings support processes with high demands on cleanliness and precision. 

They are also used in automated production facilities, where quick connection and disconnection increase efficiency, and in service and maintenance environments, where flexibility and reliability are crucial. Regardless of the industry, Cejn couplings help ensure optimal operation, reduced waste and improved work safety. 

Cejn eSafe quick couplings are designed for environments where high demands are placed on operator safety and efficient operation. The couplings are equipped with an integrated safety feature that automatically equalises the pressure when disconnected. This reduces the risk of kickback and pressure shocks, thereby providing a safer workplace.  

These couplings can be operated with one hand and are designed for both liquids and compressed air. They are available in various materials, including galvanized steel and stainless steel. We offer the 326 series in AISI 316 stainless steel, which is suitable for the food and pharmaceutical industries, and we also offer the 320 series in galvanized steel. The compact size combined with high flow capacity makes the Cejn eSafe quick coupling ideal for applications where both space and performance are critical. 

Cejn eSafe quick couplings comply with the relevant ISO 4414 standard and are often used in the food industry, pharmaceutical production and general industrial environments where safety and efficiency go hand in hand. 

In processes where fluid handling requires maximum control and minimal risk of leakage, Cejn drip-free couplings are the obvious choice. They are designed to completely eliminate dripping during both connection and disconnection, which not only improves the working environment but also reduces waste and the risk of contamination. 

Cejn drip-free couplings for fluids are typically used in processes where precision and hygiene are crucial. They are used, among other things, for transporting water, glycol, oils and various chemicals. The series includes models 577, 677 and 777, which are available with both internal and external threads. 

Cejn drip-free couplings for fluids are made of AISI 316 stainless steel, which makes the couplings resistant to corrosion and chemical influences. The compact construction allows a high flow rate, making them ideal for applications where both space and performance are important. 

When you choose Cejn couplings, you not only get access to quality products – you also get technical support and professional advice. We help you choose the solution that best suits your specific needs, whether you need couplings for liquids, compressed air or both. 

The right choice depends on factors such as media type, pressure conditions, temperature requirements, material compatibility and flow requirements. We take all these factors into account to provide you with a solution that is perfectly suited to your processes – and that meets industry standards for safety and quality. 

Cejn couplings are used for quick and safe connection of hoses and components in systems that handle liquids or compressed air. They are widely used in the food, pharmaceutical and process industries, as well as in maintenance and automation. 

Cejn eSafe couplings are quick couplings with a safety release that reduces the risk of pressure shocks when disconnecting. The drip-free couplings are designed to ensure leak-free connection and disconnection of liquids, thereby minimising both waste and the risk of contamination. 

Yes, several of Cejn's couplings, especially the spill-free models, are suitable for food production. They are made of materials such as stainless steel and are easy to clean, making them ideal for hygiene-sensitive environments.  

Yes, many of Cejn's coupling models are available in stainless steel, making them particularly suitable for corrosive or hygiene-sensitive applications. This applies to couplings in both the eSafe and spill-free series, among others.  

The choice depends on the type of medium, pressure and temperature conditions, flow requirements and material requirements. We offer technical advice to help you find the solution that best suits your specific needs and requirements.
