The bayonet adapter has one connection for ½ inch and ¾ inch hoses each. The adapter spout must be pushed into the hose. If the pump already has a different adapter fitted or bonded, (i.e. high pressure bellow), this has to be removed, pulled or cut off.

Connecting to the valve:
Place the adapter onto the valve. Push the nozzle downward – the valve opens – and twist it clockwise. This keeps the adapter locked to the valve, so that no air can escape during the pumping process.
