The Pentair 071439Z Filter Tank O-Ring is the correct replacement seal for Pentair SM and SMBW 4000 Series D.E. filters. This is a model-specific tank seal used to maintain the proper connection between filter body sections. When the original O-ring becomes brittle, stretched, or starts leaking, replacing it with the correct Pentair part is the right fix instead of guessing with an off-size substitute.
Pro Tip
Before installing the new O-ring, clean the sealing channel and inspect the clamp and tank mating surfaces. A fresh seal will not solve leaks caused by damaged hardware or debris left in the groove.
Installation Tips
Shut the system down fully and relieve all pressure before opening the filter. Confirm the filter is an SM or SMBW 4000 Series model, seat the O-ring evenly, and avoid twisting or pinching it during reassembly.
