Series 441

  • One-hand operation to connect
  • High flow capacity
  • Automatic safety locking feature


Series 441 feature a one-hand operation during connection and has an integrated safety feature that guards against unintentional disconnection. Offering an extremely high airflow rate and a grip-friendly locking sleeve makes it well suited for air cushion inflation and diving applications, especially where extra high airflow is required. Its nickel-plated brass construction makes it a perfect fit for use in damp/wet and corrosive environments. The couplings and nipples are available in a wide range of connections.
