051 Series | Single Shut Off Quick Release Couplings & Plugs
The 051 Series has a 5mm bore keyed and colour coded quick release coupling designed to prevent mix-ups when connecting multiple hose lines. Four distinct colours:
CG (green), TC (brown), HB (blue) and OR (red)
Available in male/female BSPP thread and hose tail configurations. Ideal for multi-circuit installations where cross-connection would be dangerous or costly.
