Product Details
The Series 550 coupling, featuring a 3/4" hose barb and designed for industrial interchange 1/2", offers a robust and user-friendly solution for high-flow applications. This coupling is characterized by an easy-to-grip design that requires only a low connection force, making it smaller and more compact while generating higher flows than comparable alternatives. The Series 550 couplings produce extremely low noise upon disconnection and incorporate a vented safety version that disconnects in two stages to vent the coupling, thereby minimizing the risk of sudden component separation that could lead to operator injury. The unique balanced-valve design ensures ease of connection regardless of system pressure, and the safety version is particularly suitable for manifold applications requiring multiple connection points with low connection force. Additionally, the Series 550 coupling complies with ISO standard 4414 and EN 983, emphasizing its strong and durable construction, ease of one-hand operation, and reliable performance.
