During disconnection eSafe vents the down steaming pressure, eliminating recoil and reducing noise level. In addition, eSafe has a low connecting force, compact and easy to grip design which makes it the natural choice when choosing a high performing safety product. Its extreme durability together with the many benefits will give you a reliable product for years to come.
Six reasons to choose eSafe quick connectors
-
Vented Safety function
eSafe was designed with a vented safety function according to ISO 4414. It vents the down streaming pressure before disconnection, reducing noise level and eliminating the risk of operator injury caused by recoil.
-
Easy handling
eSafe is an ergonomic and one hand push to connect and disconnect coupling. Other safety couplings usually have several steps. With eSafe, just pull the sleeve and the coupling will automatically vent before disconnecting.
-
Save energy with high flow and low pressure drop
When designing eSafe we made no compromises in performance. We are proud of the fact that eSafe has the highest flow on the quick connect coupling market. The high flow and low pressure drop means that the coupling requires less compressed air and the compressor can be set at a lower pressure. Resulting in increased efficiency and reduced production time.
-
Compact design
You should not have to compromise on size. CEJN couplings are known for their compact design. eSafe is no exception, it is the first safety coupling with dimensions like a standard quick connect coupling.
-
Extreme durability
eSafe is designed to withstand tough handling in rough work environments in order to have a long service life. Tests has proven that eSafe is extremely durable against impacts, vibrations and swiveling. Our customer testimonials all states the same fact, eSafe handles the pressure.
-
Leak free
The eSafe coupling is leak free, this means no unnecessary air loss between coupling to tool and the compressor doesn’t have to compromise for the air leakage. Production time will be reduced due to increased efficiency. This enables you to produce more in less time.
Get the job done faster and safer while saving energy
The eSafe quick couplings for compressed air are designed for safe operation with vented disconnection to avoid potential dangerous hose whipping effects and the high sound upon disconnection that too often is associated with compressed air. It's also designed with one of the market's best pressure drop performance. That will give you more power for your tools - which is key in order for compressed air to be energy efficient.

1. Do you sell eSafe quick couplings directly to end customers?
No, we refer to our comprehensive distributor network, which is available in many countries.
2. Where can I buy eSafe quick couplings?
If you are an end user, find a local distributor. If you are a distributor or OEM, you are welcome to contact your local sales contact.
3. Which compressed air nipple profile should I choose?
Each nipple profile has small advantages, but specific profiles have become standard in different markets. Go with the standard that is most common in your market. More importantly, choose quality components and avoid mixing different brands. A lesser-quality coupling or nipple paired with a better-quality coupling or nipple will not benefit from the better.
4. What's the difference between the compressed air nipple profiles?
Different compressed air nipple profiles have become the standard in different regions. Various manufacturers have developed their own nipple profiles, and depending on the popularity of a specific design in each market, the most commonly used profile has evolved into the regional standard.
The performance of different nipple profiles varies slightly. For example, CEJN’s Eurostandard profiles, such as the 320 and 410, offer superior flow performance overall. High flow performance can enhance tool efficiency, leading to increased productivity. Additionally, better flow performance contributes to energy conservation, reducing energy costs in the long term.
It’s essential to pair each nipple with its corresponding coupling. This compatibility requirement is one reason why users often replace existing couplings with ones that match the installed profile, rather than switching to a completely different coupling set with a new profile.
5. What are the different types of compressed air quick couplings?
A coupling set consists of a coupling and a nipple. It is also commonly referred to as coupling and adaptor, male/female coupling or socket and plug.
The coupling is always female, but it can be with either a male or female connection, which can also be referred to as an external or internal thread.
The nipple is always male and can have either a male or female connection (external or internal threads).
The quick coupling replaces standard threaded fittings to make switching between tools swift and efficient.
There are different types of quick-connect couplings and the most commonly used are push-in fittings or push-to-connect couplings, like the CEJN eSafe. Push-in fittings are easily and securely connected with a simple push-in action that locks the hose in place.
6. How can I recognise which compressed air quick coupling fits the existing products?
Identifying the correct nipple can be done by inspecting its profile. Each nipple standard has a distinguished profile. A trained eye can easily see which profile it is, but we also provide a nipple profile guide that can be used as a help. Most products are also engraved with an article number that you can look up on the manufacturer's website. Or you can take a picture and send it to your local sales contact, and we will be happy to help identify which type of nipple it is.
7. Can the eSafe couplings/nipples be connected with other brands' couplings/nipples?
Yes, as long as it is the same standard coupling or nipple. While eSafe has one of the best flow performances on the market, pairing it with an inferior product will not give you the benefits of a better product.
8. Are any of the nipple profiles better than the others?
The flow differs between different series, and a higher flow will generally result in higher productivity and lower costs. Nonetheless, it is often more practical to use the variants that are standard in your region.
9. When should I choose a stainless steel coupling instead of steel?
Stainless steel couplings are better in tough or aggressive outdoor environments or when used in environments with tough chemicals. Food-grade stainless steel is required for food and beverage applications. eSafe 301, 316, and some specific 326 couplings are made of AISI 316 stainless steel suitable for food-safe compressed air applications in the food and beverage industry. Please refer to the specific product specifications for the intended use of food-safe product versions.
10. Can I combine different material fittings in the same compressed air system?
Yes, stainless steel and steel couplings can be used together.
11. What material of quick coupling is the best for compressed air?
In most industrial settings or workshops, compressed air couplings and nipples are subject to wear and should preferably be made of steel or stainless steel. A damaged nipple will eventually cause leaks, leading to performance loss, production loss, and energy waste. Nipples and couplings made of brass or other soft materials should always be avoided. Tools generating vibrations put extra pressure on the nipples and locking sleeves of the couplings, making hardened steel or stainless steel the preferred choice for each part.
Leaks are costly and may be difficult to detect, making higher-grade and more durable materials like steel or stainless steel more long-term profitable for most applications.
Some applications may require specific materials, like food-grade AISI 316 stainless steel within food and beverage industries. Stainless steel offers more resistance to corrosion in outdoor applications and aggressive environments.

12. What is the expected lifetime of the eSafe quick couplings?
It depends on how often they are used, how frequently connections are made, and whether they are exposed to vibrations or other environmental factors. CEJN products undergo rigorous testing, and our tests show that you can expect that eSafe will last longer than most couplings on the market.
13. Can the eSafe be used for fluids?
Yes, but it is not recommended. It is a compressed air safety coupling that ventilates the air before disconnection to reduce the pressure and avoid high disconnection noise and hose whip effects. If it were used for liquid, the liquid would be passed through the vent and possibly onto the operator's hands.
14. Can I use eSafe for compressed air in the food and beverage industry?
Yes, the intended use of eSafe 301, 316, and some specific 326 couplings is to deliver food-safe compressed air in the food and beverage industry. The couplings and nipples from these series are manufactured in food-grade AISI316 stainless steel. Couplings from these series are fitted with specific food-grade seals and lubricants. Please refer to the declaration of conformity for full specifications of the materials and their intended use in the food and beverage industry.
