Series 525 is a family of quick couplings for hydraulic systems. Amanually operated locking ring provides extra security againstinvoluntary disconnection. An extra option for Series 525 couplings andnipples is a pressure eliminator for evacuating residual pressureduring connection. Both couplings and nipples are made ofzinc-passivated steel for maximum durability in tough applications andenvironments.
The Series is also available in four othersizes: DN 6.3 (1/4"), DN 10 (3/8"), DN 12.5 (1/2") and DN 25 (1"). Fora stainless steel version see Series 526. Available are also a versionwith viton seals and a free flow version (without valve package).
