O-Rings do not fit my 2013 blue housing 2. 5" X10
"I bought the 2. 5X10 blue housing PN H-2510-B in 2013. The O-Ring is 3. 60" OD X 0. 12" thick. The replacement O-Rings I bought last year (I think for the slimline 2. 5X10) are larger and thicker at 4. 00"X0. 15" thick, and do not fit the 2013 housing. I am buying a replacement housing and want a pack of replacement o-rings. I am hoping the 4. 00X0. 15 o-rings I bought last year fit the new blue H-2510-B housing. I attached a picture of both o-rings."
