Product Details
The Series 550 nipple features a 3/8" female NPT connection (industrial interchange 1/2") and is designed to provide a strong and durable coupling option. Series 550 couplings are characterized by their easy-to-grip design, requiring only low connection force, making them extremely easy to connect, even under system pressure. This compact coupling generates higher flows than comparable designs and produces an extremely low noise upon disconnection. The vented safety version of the Series 550 disconnects in two stages to vent the coupling, minimizing the risk of sudden component separation and the potential for operator injury. This safety version is particularly well-suited for manifold applications that involve multiple connection points and require low connection force. The couplings comply with ISO standard 4414 and EN 983, ensuring high-quality performance and safety. Dimensions and specifications vary by individual components in the Series 550 range.
