Glad to hear it. You might take one to a pool supply store and see if they have something near that size. It looks like about the diameter and thickness of the gasket that seals the clear clean out lid on my pool pump. I have soda kegs and the material is identical to the gaskets on them. I even use the same "keg lube" on them.Thanks for the concern Belga...it's all good. They were used to apply glue which is water based and cleaned up nicely with PBW & hot water. No paint & FREE., but a Hassel getting them up & running.
