Series 525 is a family of quick couplings for hydraulic systems. A manually-operated locking ring provides extra security against involuntary disconnection. Series 525 couplings and nipples have a pressure eliminator as an extra feature for evacuating residual pressure during connection. Both components are made of steel with Zinc-Nickel surface for maximum durability in tough applications and environments. The Series is also available in four other sizes: DN 6.3 (1/4"), DN 10 (3/8"), DN 20 (3/4") and DN 25 (1"). For a stainless steel version see Series 526. Available are also a version with viton seals and a free flow version (without valve package).
