Product Details
The Series 550 nipple - 1/2" male NPT (Industrial Interchange 1/2") features an easy-to-grip design and requires only a low connection force, making it suitable for various applications. The couplings are compact and generate higher flows compared to comparable designs, while also producing an extremely low noise upon disconnection. The vented safety version allows for disconnection in two stages to vent the coupling, thereby minimizing the risk of sudden component separation that could potentially cause operator injury. Its unique, balanced-valve design facilitates easy connection, regardless of system pressure, and the safety version is particularly suited for applications with multiple connection points, such as manifolds, where low connection force is essential. The product complies with ISO standard 4414 and EN 983 and is designed for strong and durable one-hand operation.
