As I get back into film and developing/printing, I was given some Falcon ChemStor plastic bottles. The cardboard liners in the caps (with plastic facing) have gone bad.

Is there a commonly available material that I could cut into circles and affix to the caps to make a good seal? (and the right kind of glue) Or should I just screw the lids on and hope they make a tight enough seal?

I save the liners from other bottles. I find a lot use what looks like a think piece of closed foam. They seal well and don't fall apart when they get wet. If you cut them the right size, they might stay in on their own, otherwise try a dab of hot glue.

I always cut a piece of a lab material called Parafilm and put it over the mouth of the bottle before putting a cap on. This or even wax paper will ensure that there is a tight seal on the bottle and that you will not get any contamination from the liner of the cap. In a lot of cases the cap from the fixer may end up on the developer than can result in the contamination of the developer.

A couple layers of plastic kitchen wrap (Saran, etc.) works well for me.

I replaced the card seals in a whole bunch of bottles recently with some neoprene gasket material. It cost me all of about $2 for enough to make around 10 seals. I think they should last a little while as well!

I'll check the gasket material idea, hoffy; thanks!

In the meantime, it seems that the bare plastic bottle cap without the cardboard does screw all the way down and probably makes a good seal contact with the plastic bottle. I'll give that a try for at least the short run and see how it works.
