Rubber Bung 25-29mm With 10mm Thread 4689032
We have constructed a special 25-29mm Rubber Bung that allows the use of a flex up to 6.8mm in diameter.
There is room on the bottom for a female cord grip to be added but it will spin when the bung is tightened up.
The bung is tightened by using a 13mm spanner on the top nut until a snug fit.
Please Note: Our nut covers will not fit onto this bung as the brass washer is bigger than the diameter of the nut cover.
Fits a bottle: 25-29mm
Inside diameter max: is 6.8mm
