Bulkhead O-ring part #

[pinch52]

Hi all,
I have a pentair FNS 60 filter and the bulkhead union orings(in the picture) are leaking. Anyone have a part number for these? Thank you!!

Try Pentair #192320 or Pentair #86006900……it looks like the first part number might be superseded by the 2nd, but I haven’t taken the time to verify in detail.
