SERIES 090.V0
coupling, protected by twisting the locking nut, Article: N0QC1
Image similar to the originalArticle: N0QC1, Nominal Width|5 mm, Connection|LW6, Flow Rate|600 l/min
Nominal width 5.0 mm, material: brass, surface: nickel plated, single shut off, connection type: hose connection, connection size: LW6, seal: FPM (Viton)One-hand coupling with automatic 5-point locking. Locking elements are balls which are locked by a spring-loaded unlocking sleeve. Disconnect by pushing the release sleeve back into the direction of the connection. The valve moves back to its original position and closes the coupling. All couplings in this series have an additional lock nut to secure the coupling against accidental uncoupling.Material coupling: back part, sleeve and coupler body brass nickel plated. Valve brass nickel plated. Locking nut anodised aluminium. Seal FPM ( Viton). Spring and circlip stainless steel AISI 301. Balls stainless steel AISI 420.
