Hello people, I have a stainless steel, Diatomaceous earth filter and I took it apart to clean it. The oring to seal the top cap of the filter to the bottom, is not round like a lot of filter O rings, but flat and comes up into t triangular shape, just like older auto fan belts were shaped. If anybody can tell me how to search for this type of oO ring it it would be greatly appreciated, I keep coming up with round ones only, 58 inches would be the diameter. Thanks to anyone who can help, pic of filter with O ring on it attached.
