This is probably a stupid question but does anyone know the material typically used for making hydrostatic diaphragms that go underneath the Environmental Caps used on sealed diaphragm first stages. Kind of like how some people make their own LP seats with a sheet of rubber and a punch tool. I can obviously use a digital caliper to measure their thickness.
I have a lot of first stages and I typically try to keep an excel spreadsheet of when they were "last" serviced by the serial number on the first stage.
For all my Apeks first stages that have a clear hydrostatic diaphragm I use a label maker to put my name and date last serviced underneath the sealed environmental cap. I think a lot of people do this but I wish I could do it on my non-Apeks first stages so I can quickly glance to see when it was last serviced.
I'd like to make up a bunch of "clear" hydrostatic diaphragms so I can do the same thing on some of my HOG and even Deep 6 first stages.
