One of my EHPro KFL+ fill screw o-rings has seen better days. Only a matter of time before it gives out. I want to grab some to have before I really need them. Tried a few different ones from my local hardware store from the plumbing section, They were the correct id, but they were too thick to fit in the hole. Only place I have seen them is on ebay. But they are from a UK seller. Any US retailers carry them. Or has anyone found a supplier that carries a size that will fit???
