Cejn 115 Series Hydraulic Couplers & Fittings

Cejn 115 Series Hydraulic Couplers & Fittings

Specialised Force are Authorised Australian Distributors for the Cejn range of high-pressure hydraulic couplers (also known as snap couplings or quick disconnect couplings) and hydraulic fittings.  NOTE: Series 115 is available in both standard and Flat-Face designs.  

The 115 series of hydraulic quick connect couplings for ultra-high pressure are easy to handle, safe and reliable. The quick couplers are available in both standard and flat-face designs. Series 115 are non-drip couplings with clean connection and disconnection protecting both the environment and circuit integrity. The safety lock comes as standard and it adds an extra layer of safety by eliminating any risks of accidental disconnections. The high performance and robust design with small outer dimensions, makes it a suitable option in many different applications. The nipples are also available with a hose rupture valve. In the event of a ruptured hose, the nipple closes and prevents oil spills that could disrupt production and harm the environment. Plastic dust caps come as standard for both the couplings and nipples. These extend the lifetime of couplings, nipples and the entire hydraulic system. Aluminium dust caps are also available upon request.
