Extra
I bought this for a spare at my age it is easy to lose or misplace things I use.

Ordered a couple to have on hand as these are small and thin and I'm sure will need to be replaced. The size if then though is odd as they are larger then ones I was finding locally so added them to order I was making to have extra of. Used originals now for a year and no issues.

It takes a little mucking about to get the o ring in place but they do seal well.
