WEO Plug-in Coupling

A compact coupling solution for use with an existing manifold design. The WEO Plug-In coupling offers a multitude of thread or tube connections to replace your current screw fittings. No tools are needed for hose assembly.

WEO Plug-in Cartridge

WEO Cartridge is a refined component made for compact system integration. With the WEO cartridge fully integrated into the component design, it will open up new opportunities for a more compact design.

As no adapter is needed, costs are reduced and at the same time, one potential leakage point is eliminated. Reduce the footprint of your final design and enjoy extensive cost savings.

WEO Plug-in Swivel

The ideal solution for applications with pressurized moving and rotating hydraulic hoses is the WEO swivel. The WEO Plug-In swivel can rotate 360° while under full working pressure and includes a combined ball and slide bearing, accommodating both hydraulic and torsion forces, resulting in significantly increased service life for your products. WEO Swivel is both a swivel and a plug-in fitting and is as small and flexible as the basic version of WEO Plug-In, giving you a size and weight advantage over commonly-used swivel solutions.

WEO Plug-in Nipple

WEO is designed with an innovative push-to-connect feature that provides quick and quality-assured engagement of the product´s male and female halves. The only time you need a tool is to remove the assembly stop when disconnecting, and this can be done with a screwdriver or similar. Once the assembly stop is removed, you simply push the male nipple all the way in and pull it out from the female component.

The WEO nipple is an open standard. Are you interested in manufacturing your own WEO nipples? Get in contact with us today.

Screw Fittings vs WEO Plug-In

Under or over torque

Torque values are based on calculations and comprehensive testing and getting these values right on the assembly line requires precision. Personnel need to be well trained, have calibrated tooling and be able to access the components to be assembled, which are often difficult to reach and tighten. All of this often leads to over or under torque during assembly. The result is leakage during final testing or later on when the product is delivered to a customer. This leads to costly re-working and claims. All these problems can be solved with WEO, as you just plug in.

Embedded tension from torque

When applying torque to screw fittings there is a big risk of embedded tension in the hoses. As strained hoses are subject to pressure impulses, hose movement and even rotation during operation, the lifetime of any such hose is dramatically reduced, resulting in premature failure and leakage. Premature hose failure frequently leads to warranty claims and can be very costly. With the self-aligning WEO Plug-In, such hose and leakage problems are solved, and with the WEO Swivel, extreme hose movement and full rotation under pressure are no problem at all.

WEO Plug-In Coupling - For quick and safe assembly

Operator safety and quality assurance in focus

In the confined space between chassis and cabin, the operator has to carry out hose connection with a heavy cabin hovering over his head – a very exposed situation. Users of screw-connect fittings always have the challenge of achieving correct torque. Imagine performing this task with no room at all for tools. In many cases this results in leakage from couplings and embedded tension in hoses that subsequently leads to leakage. With WEO you can work quickly and avoid leakage problems, since all you have to do is plug in.

SAVE TIME
The fact that all you have to do is plug in means a considerable reduction in assembly time.
HEALTH & SAFETY
No torque processes in confined spaces that could cause personal injury. Exposure is minimised thanks to a quick assembly process. Good ergonomics – you just plug in and thus avoid awkward postures that can cause strain.
MINIMISE LEAKAGE
With WEO, no torque process is required and leakage problems are avoided – just plug in.
EXTENDED HOSE LIFE
With our self-aligning WEO, hoses last longer. No embedded tension to wear them out.

The simplicity of working with WEO Plug-In

The nipple is connected to the coupling by simply plugging in.
The nipple is securely locked with the unique WEO locking hooks.
Using a screwdriver, remove the assembly stop.
Push the nipple all the way in and then pull it firmly out.

WEO Plug-In Cartridge - For integrated and compact design

WE ARE ALWAYS ON THE LOOK-OUT FOR SMARTER SOLUTIONS. With its minimal space requirements, the WEO cartridge allows designers to design new compact hydraulic systems. When incorporating this compact cartridge into your design, you can minimize the footprint of the final design by reducing the space between the ports. This means less material required and reduced costs. Again, since our fittings simply plug in, you don’t have to worry about hand-tool clearance, unlike traditional screw fittings where extra clearance for tools is required when tightening.

MINIMISE LEAKAGE
No torque, no leakage – just plug in.

SUPER COMPACT
By integrating the WEO cartridge into your design, you can minimize the footprint thanks to its compact size. In addition, no tools are needed during hose assembly.

SAVE TIME
The fact that all you have to do is plug in means a considerable reduction in assembly time.

EXTENDED HOSE LIFE
With our self-aligning WEO, hoses last longer. No embedded tension to wear them out.

HEALTH & SAFETY
No torque processes in confined spaces that could cause personal injury. Good ergonomics – you just plug in and thus avoid awkward postures that can cause strain.

WEO Plug-In Swivel – For extreme swivelling applications

EXTENDED HOSE LIFE
With our self-aligning WEO, hoses last longer. No embedded tension to wear them out.

SAVE TIME
The fact that all you have to do is plug in means a considerable reduction in assembly time.

HEALTH & SAFETY
No torque processes in confined spaces that could cause personal injury. Exposure is minimised thanks to a quick assembly process. Good ergonomics – you just plug in and thus avoid awkward postures that can cause strain.

MINIMISE LEAKAGE
WEO Plug-In Swivel eliminates problems with unscrewing and embedded tension in hoses and can handle extreme hose movement and rotation.

WHEN IT COMES TO APPLICATIONS WITH EXTREME HOSE MOVEMENT, the obvious solution is the WEO Swivel. A truck-mounted crane causes the hoses on the valve blocks to twist and rotate in a way that causes them to wear out. When using the WEO swivel, the hoses can move freely and self-align, with 360-degree rotation under full working pressure. The result is longer hose service life and fewer claims.

Reduce the overall costs with WEO

On the drawing board
The designer has scope to create more compact and smarter designs with our small and flexible WEO solutions. Designs that will reduce both size and costs.

On the assembly line
If you are working on improving the efficiency of your assembly line, you will first become aware of the time you save. Plus the possibility of making mistakes is eliminated. With a simple plug-in, the connection is achieved without any complicated torque calculations. You often also need to fit a torque wrench into narrow spaces where application of torque is impossible. With WEO, the job is done in no time. It can reduce the time for final testing, as WEO is a Poka-yoke solution.

The machine owner
As an owner of a WEO-equipped machine, you will save both time and money. Instances of twisted hoses that burst due to rotation will be minimised and countless hours will be saved thanks to simplified disassembly.

WEO Nipple – The Global open Standard

By releasing the male part (nipple) as an open standard, CEJN sees a future where WEO is even more accessible around the globe thanks to more manufacturers and shorter distribution chains.

Co-operation is now available from CEJN to customers who wish to receive support in their manufacturing process of nipples. Just a registration and an agreement that the CEJN specifications are followed. It should be easy and accessible to become a WEO nipple manufacturer.

As always when an open standard is created, it is to protect the reputation of WEO and to ensure that the end user gets interchangeability, highest quality, performance and safety. The CEJN service will consist of specifications such as drawings and process parameters to reach specified performance and quality level. If changes are made on those parameters, CEJN will update the registered manufacturers.
