Mercury / Mariner Inflatable Pump Nozzle

Tired of buying an inflating head each time to replace the one lost somewhere or fallen overboard ...

At least one ring must be printed in Flex material if possible..
Feel free to combine other rings in order to have a correct fit with the valve.

You can put a small screw 16mm long and 1.5 to 2mm wide to push on the valve if necessary.

As a simple return, please like and post your make ;)
