Quick overview
- Genuine Pentair part The OEM 071439Z filter tank o-ring, not a generic substitute.
- Date range matters This o-ring is called out for filters manufactured between 3/03 and 7/03, so the build date decides which ring you need.
- 19-1/4 inch inside diameter Measured ID of the ring, with a 1/2 inch thickness.
- Rubber construction Listed as a rubber o-ring for pool filter service.
- Tank seal duty This is the seal between the filter tank halves, so it is the part that stops a band clamp leak.
- Lubricate on assembly A silicone based o-ring lubricant helps the ring seat evenly and makes the next teardown easier.

Product details
Pentair 071439Z is the OEM filter tank o-ring measuring 19-1/4 inches on the inside diameter with a 1/2 inch thickness, in rubber. It is specified for filters manufactured between March 2003 and July 2003.
Check the build date
The date window is the whole point of this listing. Tanks that look identical from the outside can take different rings depending on when they were built, so read the manufacture date off the filter label before you order rather than measuring by eye. Getting this wrong is the usual reason a fresh o-ring still weeps at the clamp.
What it fits
It is listed for Pentair Clean and Clear Plus cartridge filters, Purex CFM fiberglass cartridge filters in models CFM 120, 180 and 315, and Purex 4000 Series molded DE filters in the SM and SMBW models 4024, 4036 and 4048.
Fitting
Clean the groove and the sealing face before the new ring goes in, and use a silicone based o-ring lubricant so the ring seats evenly instead of rolling as the clamp comes together.
