You could make one.
There’s a page about how on this site.
Also, there are at least a couple of on-line parts stores that may have what you need depending on the pump model. Google is your friend.
I have since discovered the compressor is manufactured by IMC-Atlas Copco and it is a model B3800. I found a gasket kit at mastertoolrepair.com as well as an ample parts list for this compressor.
