Keeping them alive
Warm water, regularly
A food grade vegetable oil, a thin film not a glob
Stretched or cracked means it is done sealing
Pick your exact device so the fit is correct
Pro tip
Do this daily
Clean and lube your o-rings daily with a vegetable oil of your choice. It stops the sticking, extends their life, and keeps the top cap sliding instead of fighting you. Do it after any alcohol clean without exception, because iso strips the oil right out of rubber.
