WEO Fittings (plug-in)

WEO plug-in fittings

WEO fittings (plug-in) are a standard developed by CEJN. The WEO plug-in works well in hydraulic systems where there is not enough space to mount a hydraulic hose using traditional fittings (assembly without the use of wrenches). Additionally, the plug has freedom of movement in the connection port, which prevents the hoses from twisting during assembly. WEO fittings are designed for single and double-braided hoses. Seal: O-ring (in the connection port). Working pressure: 350 bar up to DN19, 250 bar from DN25. Material: hardened steel. Working temperature: from -30°C to +100°C. WEO is used, among others, in front loaders of renowned companies such as QUICKE and TRIMA, Komatsu machines, FASSI cranes and many others.

WEO connection system

WEO (Walter Essential O-rings) couplings are an innovative hydraulic coupling system that provides convenient and reliable connections in hydraulic systems. The WEO system includes special fittings and couplings that are easy to assemble and disassemble, while ensuring high durability and tightness of the connection. Fittings in the WEO system are designed to enable fast and trouble-free assembly without the need for specialized tools. Thanks to this, you can save time and effort when installing hydraulic hoses. WEO fittings are equipped with special O-ring seals that ensure excellent connection tightness. WEO couplings are available in various configurations, such as elbow, tee, Y-couplings, and straight connectors. They can be used in various hydraulic systems, from single lines to more complex systems. WEO couplings are made of high-quality materials that ensure durability and resistance to operating conditions.

Benefits of the WEO system 

The WEO system offers many benefits, including: Easy assembly: WEO fittings can be quickly and easily crimped onto hydraulic hoses, which speeds up the installation process. High tightness: O-ring seals in WEO fittings provide excellent tightness, eliminating leaks and pressure losses. Durability: WEO couplings and fittings are made of durable materials, which guarantees a long service life and connection reliability. Versatility: The WEO system can be used in various industries and applications, including industry, construction, agriculture and many others. Thanks to its simplicity of assembly, reliability and durability, the WEO system is a popular choice among power hydraulics specialists. It provides effective and safe connections in hydraulic systems, contributing to their efficient operation and saving time and costs.

CEJN WEO couplings

Modern leak-free hydraulic connections. CEJN WEO couplings are an innovative solution in the field of power hydraulics, allowing for fast, safe and tool-free connection of hydraulic hoses. The WEO system was developed by the Swedish company CEJN – one of the leaders in the production of couplings and fittings for industrial applications. What makes the CEJN WEO system stand out? WEO couplings are a patented "plug-in" type system that eliminates the need for wrenches and seals during assembly. One push is enough for the connection to be ready for operation. The design based on an automatic snap mechanism ensures 100% tightness even at high working pressure, and at the same time allows for multiple disconnection and reconnection without loss of tightness.

Key advantages of CEJN WEO couplings:

• Safety and no leaks – the automatic latch eliminates the risk of an under-tightened connection.

• Time saving – assembly and disassembly take a few seconds, which shortens service downtime.

• Longer system life – no torsional stress in hoses and couplings due to the swivel design.

• Compact design – ideal for machines and equipment where assembly space is limited.

• Resistance to vibration and high pressure – proven in mobile, agricultural and industrial applications.

Practical application of WEO couplings

CEJN WEO couplings are modern solutions that have found wide application in many industrial and mobile sectors. Thanks to their design, they enable fast, clean and completely leak-proof assembly of hydraulic hoses without the need for tools. They are most often used in construction and agricultural machinery, where the reliability of connections in conditions of high vibrations and variable loads is crucial. The WEO system also performs excellently in mobile hydraulics, meaning everywhere where hoses must be frequently disconnected – e.g. when servicing equipment or replacing components. In production lines and industrial equipment, CEJN WEO couplings are used due to assembly time savings and the possibility of working in confined spaces. Their compact design allows designers to create more compact hydraulic systems without the risk of leaks. They are equally often used in service applications where quick intervention is required, and the cleanliness and safety of the system are of key importance. Thanks to the plug-in system, the hose can be plugged in with one move, without oil leaks and without the need to tighten fittings. The CEJN WEO system comes in several varieties adapted to different types of assembly: WEO Plug-In – this is the classic version of the coupling, which enables fast connection of a hydraulic hose without the use of wrenches, which significantly shortens assembly time. WEO Cartridge – a variant intended for direct installation in the body of a machine or device, thus eliminating the need for additional adapters and increasing the reliability of the entire system. Both versions of the couplings are characterized by high tightness, durability and resistance to loads, which makes CEJN WEO couplings a standard in many modern hydraulic systems.
