Specialised Force is the authorised Australian Distributors for the Cejn range of high-pressure hydraulic couplers (also known as snap couplings or quick disconnect couplings) and hydraulic fittings.
A CEJN original that customers have relied on for over 40 years, Series 125 features extremely small outside dimensions and a patented seal design. The series is a dependable performer on bolt tensioners, bearing pullers and other applications.
