When working with high pressure, which has enough power to cut off a limb, for example, safety is an absolute must. This is why safety plays a key role in product development at CEJN.
Identify the risks of high-pressure hydraulics
In a hydraulic system, power is transmitted with the help of a liquid. Modern systems usually use oil, which is pressurized with a pump. Hydraulics makes it possible to generate high forces, and in high-pressure hydraulics, the pressures and forces are even higher. This also increases the severity of accidents.
If a hose breaks, it can lead to an oil leak, which can cause serious injuries. Injuries caused by a high-pressure, punctiform oil jet are usually more serious than they first appear, as the oil can cause severe internal tissue damage. It can even result in the loss of a limb. In addition, oil spills—however small—may cause slip hazards, which is a major safety risk. Furthermore, incorrectly installed hoses may loosen from the coupling, causing a hose whiplash and possibly resulting in serious damage.
Watch a simulated video of high-pressure hydraulics incidents
High-pressure hydraulics is not to be trifled with, as the consequences of using products that lack on quality and reliability can be devastating. CEJN’s video demonstrates the potential hazards of high-pressure hydraulics.
The video starts with showing what kind of damage a coupling failure can lead to. The second simulation describes the damage a broken hose can cause to a worker.
Manufacturer-tested high-pressure hydraulic products are reliable to use
In high-pressure hydraulics, the use of high-quality products cannot be overemphasized. Hoses and high-pressure hydraulic couplings face pressure that can cause serious damage if released, which means you need to be completely sure of the durability and functionality of the components.
CEJN is a leading manufacturer of high-pressure quick couplings and fully committed to safety. All CEJN products have undergone rigorous testing and approval processes, ensuring that you can rely on them in your work.
It is important to remember that genuine CEJN products must not be used in combination with copies. CEJN cannot guarantee the safety of its products if they are used together with other manufacturers’ products.
It is also worth noting that it is impossible to visually assess the tightness of high-pressure hydraulic couplings. Although the coupling may appear to fit at first sight, it isn’t necessarily durable and secure enough for demanding use. CEJN’s tested high-quality products are a safe choice in this respect.

CEJN has introduced an alert ring that helps users to check the correctness of the connection visually.
Three ways to improve the safety of high-pressure hydraulics:
1. Choose high-quality products
Invest in tested high-quality products, hoses and couplings. Do not combine products from different manufacturers. If you do, the manufacturers cannot guarantee the safety of their products.
2. Be careful when using equipment
Working with high-pressure hydraulics always requires special attention. From a safety point of view, following instructions is essential.
3. Check the condition of the system
High pressure causes wear and tear on components, which stresses the importance of monitoring and regular maintenance. Even high-quality couplings and hoses need to be replaced at regular intervals.
The employer is responsible for the safety of workers
Watch the CEJN’s video to see what happens when a damaged or faulty high-pressure hydraulic hose breaks down next to someone. When it hits the skin, a punctiform, sharp jet of oil cuts through tissue like a water jet. Even minor work-related accidents are risk to both the employee’s health and the employer’s business. Prevention is always more cost-effective than repairing the damage.
According to the Finnish Occupational Safety and Health Act, employers are obliged to take the necessary measures to ensure the safety and health of their employees at work. How about we start with updating the high-pressure hydraulic products?
CEJN’s products have numerous safety features
CEJN has developed a number of safety-enhancing features for its high-pressure hydraulic products. Here are a few examples:
Drip-free connection
All CEJN’s high-pressure hydraulic couplings and nipples form a tight connection that prevents leaks into the environment as well as air from entering the system during connecting and disconnecting.
Service life tracking of hoses
In CEJN’s CiS system, each hose kit is chipped for traceability. This helps to determine when it is time to take the hose out of service, for example.
Quick safety lock
All CEJN’s couplings within the next-generation range have a safety lock as a standard feature to prevent unintentional disconnection. A quick locking ring ensures a safe connection.
CEJN alert ring
The CEJN high-pressure quick connect couplings have an alert ring that clearly indicates if the coupling is properly secured. The connection is safe, when the red ring around the coupling is completely hidden. If the red ring is still visible, the nipple may shoot out under pressure.
CEJN’s high-pressure hydraulic couplings are renowned for their excellent quality, durability and safety. Unfortunately, new products that resemble CEJN’s and attempt to capitalize on our excellent reputation, have recently emerged on the market.
