ZUMRO Inc. is now using a new "Air Bottle Hose" coupling on the shelter and the hose. The new coupling design offers an additional safety lock to prevent accidental disconnect while inflating the shelter using high-pressure air bottles.

The new coupling and hose connection has locking ball bearings that fit into an extra groove to ensure a tight locking connection.

Connection and Disconnection Instructions;

To Connect - Firmly push hose nipple into shelter coupling. The locking collar must "SNAP" back and lock onto the hose.

To Disconnect - Shut off any air supply to the hose. Push the hose nipple towards the shelter coupling. Slide the locking collar towards the shelter to release the hose connection.
