I'd just buy a rubber one at the hardware store if the trip to the LHBS is out of the way. It won't hurt for a few days so you can tune in the kegerator and try it out. They may even have a silicone or neoprene washer there. I never looked.
Sometimes the sun shines in, and I close the blinds, cause I can't stand to see the light of day. I have no use for pain, but I don't mind the rain, cause I can stay inside and hear the sound.
Today I look right down, right down to the ground, there's nothing in between to break by fall. I'm blue for you, and I don't know what to do.
