CEJN X64 Range- Superior pressure relief facilitates easy connection
with residual pressure in the system

Always Easy to Connect
Never again will residual pressure be a problem when
you need to connect hydraulic lines• Flat-Face design• Connection under pressure• One-hand operated• Small dimensions• Conforms to ISO Standard 16028

With CEJN’s X64 range you can easily connect
your tools with residual pressure in the system

1. When connected the pressure relief valve opens and the pressure is punctuated. Once thepressure is equalized the nipple is easily connected
2. The coupling and nipple fully connected.

Residual pressure

Pressure relief

Residual pressure is mostly caused by expanding oil due toelevated temperatures and results in a substantially increased connection force making the coupling and nipple virtually unconnectable. These types of problems are usually solved by unscrewing
some of the threaded connections to bleed out the residual pressure or puncture the pressure by force. In doing so, the surfaces of
the coupling or nipple are usually damaged, the frequency of costly
down times is increased and the risk of environmentally dangerous
leaks becomes higher.

With a built-in pressure eliminator the residual pressure is punctuated during connection and the pressure is equalized making it possible to connect the hydraulic system without the need for extensive
force. Consequently, a fast and easy connection process is ensured
and hydraulic spillage is eliminated.

Series X64– Series 264, 364, 564, 664 and 764
CEJN Series X64 offer quick-connect nipples with a built-in pressure eliminator that does
not make their design unnecessarily large and bulky. The pressure eliminator solves
problems with high connection force due to residual pressure on the nipple side. It
punctures the residual pressure and ensures a low connection force without any hydraulicleakage. The Series are interchangeable with the ISO 16028 Standard and therefore asuitable complement to Series X62 and X65.
