Series 526, DN25
- Stainless steel (AISI 316)
- High durability
- Manual locking ring for extra security
Series 526 is a family of quick couplings for hydraulic systems. A manually operated locking ring provides extra security against involuntary disconnection. All parts in both couplings and nipples are made of stainless steel 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 12.5 (1/2″) and DN 20 (3/4″). For a steel version see Series 525.
