I have a Pentair 420 Model 178557 Rev E which I need to replace the 0-ring which has enlarged over time and hard to reassemble after cleaning filters. Please confirm the correct part # so I can order it from you. Thank, Dale D

Hello - if you have the Pentair Clean & Clear Plus Cartridge Filter, this is the correct replacement tank body o-ring. Unfortunately, I cannot verify that model number (178557) in our database or Pentair's catalog. Can you confirm on your end that the amount listed above is correct?

Is this the correct o-ring for a purex triton fns plus de filter? I found the bag of the one we're currently using and it says American o-497-9. When I compare the two, they are different diameters and thickness. Which one is the correct one? Thanks!
