Where can I get this "foam" gasket material?
« on: December 20, 2021, 02:18:18 pm »
It's used on many things such as the gasket inside the screw-on cap of a spray bottle. It's also on the inside of my alcohol dispensing container bottle and other types of plastic bottle caps. I need to make some more to fix some bottle leaks. I cannot find this in a craft store. It's 1 mm thick. It is not hard plastic, it's some type of foam.

Does anyone know what it's called and where I can get a sheet of it (I'll make my own gaskets from the sheet).

Thanks.

I told my friends I could teach them to be funny, but they all just laughed at me.

By look and feel, it is a high density PE (or PP) foam that is slightly resilient and chemically resistant.  Finding it in larger sheets, if that is what you want, may be difficult.  At least that is a lead.  I have dealt with that company before.  The largest that link shows is 12 cm.  Is that big enough to cut what you need?

Hey thanks! Your link called them "foam cap liners". With that search term, I found some on Ebay, in different diameters. I can cut them if I need to.

Just needed a good search term.  :-+

Thanks!

McMaster calls it closed-cell foam, they have it in a variety of thicknesses too.
