Threadless WEO Plug-In cartridge coupling system
The CEJN WEO Plug-In cartridge system is engineered for compact hydraulic manifolds, control blocks, and mobile machinery valving. Threadless click-to-connect fitting integration drastically decreases factory assembly time while eliminating leakages induced by overtightened or damaged pipe threads.
360-degree hose rotation prevents torsional stress and prolongs high-pressure hydraulic hose service life.
ultraFLOW liquid cooling and thermal control couplings
The CEJN ultraFLOW series is tailored for direct-to-chip liquid cooling systems in enterprise data centers, AI compute clusters, power electronic converters, and medical MRI systems.
Sizes 107 through 707 deliver exceptional coolant flow rates with negligible hydraulic pressure drop across the cooling loop.
Hard-anodized aluminum and stainless steel body options with specialized EPDM and FKM elastomer seals.
Multi-X multi-coupling plates for simultaneous connection
CEJN Multi-X Generation II multi-coupling plates allow simultaneous connection of two to six hydraulic lines and auxiliary electric circuits. The mechanical lever mechanism enables effortless coupling against trapped residual pressure while eliminating line cross-connection errors.
Integrated lever lock and automated residual pressure relief mechanism for construction attachments.
Safety Reels hose reels and polyurethane PUR tubing
CEJN Safety Reels self-retracting hose reels and reinforced polyurethane PUR hoses provide safe delivery of compressed air, industrial fluids, and electrical power. The patented centrifugal drum brake controls rewind speed, preventing hose whip accidents and protecting surrounding machinery.
Spark-resistant hose options, oil and UV resilience, and 180-degree wall mounting swivel bracket.
Breathing air certified quick connect couplings
CEJN Breathing Air quick connect series 340, 341, 342, 344, and 346 are built for personal life-support apparatus, firefighting equipment, diving gear, and hazardous chemical response suits. All products comply stringently with European life-safety directives EN 14593 and EN 14594.
Dual-action disconnect sequence prevents involuntary decoupling during emergency intervention.
Engineering parameters for CEJN coupling selection
Continuous and maximum system pressure, nominal diameter (DN), thread connection standard (BSP, NPT, metric), chemical fluid compatibility, and temperature window.
Replacement nipples and preventive maintenance kits
Precise CEJN nine-digit catalog reference, elastomer seal compound (NBR, FKM, EPDM, FFKM), coupling photograph, and abrasive plant environment profile.
CEJN Group legacy and Swedish engineering precision
Headquartered in Skövde, Sweden, CEJN is an internationally renowned leader in the engineering of high-performance quick connect coupling systems for compressed air, hydraulics, and fluids.
Founded in 1955 by inventor Carl Erik Josef Nyberg, the company pioneered the modern quick-disconnect sector with its first patented airtight pneumatic coupling. Today, CEJN operates cutting-edge manufacturing facilities that meet rigorous European quality, reliability, and environmental standards.
CEJN products perform reliably across modern automotive assembly plants, machine tool centers, offshore energy platforms, wind power stations, heavy shipbuilding yards, and aerospace manufacturing facilities.
Scandinavian manufacturing excellence ensures micrometer-precise tolerances, superior sealing integrity, and extended fatigue life under relentless mechanical pulsation and industrial vibration.
eSafe pneumatic safety standards and energy conservation
The CEJN eSafe quick coupling portfolio represents the benchmark in industrial pneumatic line safety and compressed air conservation.
Operating through an intuitive two-stage disconnection mechanism, eSafe couplings fully prevent hazardous hose whip accidents mandated by ISO 4414 and EN 983 standards. On the first push of the release sleeve, the valve shuts down main supply and depressurizes the downstream hose silently.
The second action unlocks the nipple safely. Boasting industry-leading flow coefficient values, eSafe minimises pressure drop, generating up to thirty percent savings in compressor electrical power across automated manufacturing floors while protecting workshop technicians.
Ultra-high pressure hydraulic excellence up to 4000 bar
Within the demanding ultra-high pressure hydraulics segment, CEJN equipment is the global benchmark for operating pressures between 700 and 4000 bar (up to 400 MPa).
Coupling series 115, 116, 125, and 140 incorporate flat-face non-drip valves and mechanical safety lock rings that prevent accidental decoupling under severe impulse peaks.
Combined with factory-crimped multi-spiral steel reinforced hoses and the CIS radio frequency identification system, CEJN provides supreme operational safety for bolt tensioning tools, bearing pullers, rescue cutting tools, and hydrostatic testing stations worldwide.
CEJN WEO Plug-In technology revolutionizes hydraulic hose installation on compact directional control valves, gear pumps, and hydraulic drive motors. Fittings click smoothly into cartridge bores without pipe wrenches, accelerating factory production line throughput and enabling tight port spacing.
The continuous 360-degree rotation of the fitting under pressure prevents torsional twisting of flexible rubber hoses, multiplying the service life of high-pressure hydraulic hose assemblies across demanding mobile forestry, mining, and agricultural equipment.
Precision liquid cooling and ultraFLOW thermal management
The expansion of enterprise AI compute infrastructure and dense data centers mandates zero-tolerance leak safety in direct liquid cooling loops.
CEJN ultraFLOW and Non-Drip coupling series provide dry-break disconnection with zero fluid spillage, safeguarding sensitive electronics and computing blades.
Machined from hard-anodized aluminum and AISI 316 stainless steel with specialized EPDM and FKM elastomer seals, ultraFLOW features optimized hydrodynamics that maintain low pump resistance and steady temperature regulation across primary cooling loops.
Multi-X multi-coupling plates for heavy mobile hydraulics
CEJN Multi-X Generation II multi-coupling plates permit the simultaneous connection of up to six independent hydraulic circuits and electrical lines with a single ergonomic lever motion.
The mechanical cam transmission smoothly overcomes residual trapped hydraulic pressure, enabling fast implement changes on excavators, wheel loaders, and municipal attachment machinery without environmental contamination or oil leakage.
