Is the 18 inch O ring mean the diameter of the tank is 18 inches?
 Reply

A  Answered on 5/17/2018 by InyoPools Product Specialist Hector F.

Not necessarily because the o ring may sit in a channel that may make the actual filter diameter different based on the mold design. Ultimately you really want to try your best to locate the specific filter model to cross reference parts for it.

Hello, We have an OLD Pac Fab DE Filter. We think the part # for the filter 19-3440. We need an O-Ring replacement. We think it is approx 17 3/4". The configuration seems to be beveled but I read that the O-ring can become flattened over time. What O-Ring do you suggest? Thanks for the help!

Hi Dixon.  There are a number of old Pac-Fab DE filters out there and we probably have parts for all of them!  Send some pictures of the filter and any labels that might be on it (even labels on the filter valve can be helpful) to upload@inyopools.com so we can be sure to recommend exactly what you need.
