Vacuvin pump with jar seal - trimmed seal

Bicycle inner tube stretched over the end of a Vacuvin pump to create a cushioned seal between the hard plastic of the Vacuvin and the hard metal surface of a jar lid.

 

This allows the use of a Vacuvin wine saver pump on storage jars with home-made valves to vacuum dry-store food.
