Product Overview

The Pentair 071426 collar and rotor union O-ring is a critical sealing component used in pool and spa filtration systems. Installed at the collar and rotor union connection, the O-ring forms a secure barrier that prevents water leaks where plumbing components connect to the filter assembly. Maintaining a proper seal at this location is essential for preserving system pressure and ensuring reliable filtration performance.

Manufactured from durable chemical-resistant rubber, the O-ring is designed to withstand exposure to water pressure, pool chemicals, and temperature changes commonly present in filtration equipment. This replacement gasket is commonly used during routine filter maintenance to restore proper sealing performance and help keep compatible cartridge and D.E. filtration systems operating efficiently.
