Product Overview

The Pentair 87300400Z Clean & Clear Posi-Clear Tank O-Ring is a replacement sealing component used in compatible cartridge filtration systems. Positioned between tank sections, the O-ring plays an important role in maintaining the sealed interface needed for proper filter operation. When the original seal becomes compressed, brittle, cracked, or otherwise compromised, replacing it is an important step in restoring the filter assembly to proper working condition.

This part is well suited for routine maintenance, targeted repairs, and scheduled filter service on existing Clean & Clear and Posi-Clear systems. Rather than replacing larger filter components, the correct tank O-ring allows service professionals and pool owners to address a specific wear item that directly affects sealing reliability and long-term performance. For compatible Pentair filter systems, this replacement seal helps support dependable operation and continued equipment serviceability.
