Series 550 couplings feature an easy-to-grip design and require only a low connection force. They are smaller, more compact and generate higher flows than comparable designs. Series 550 couplings have an extremely low noise level upon disconnection. Included in the series are anti-hose whip nipples.

Series 550 is also available in a Vented Safety version.
