Who It's For

This O-ring is aimed at pool and spa owners or service technicians who specifically own Zodiac CV or CL cartridge filters or Jandy DEV/DEL D.E. filters and need a like-for-like tank seal after disassembly. It is especially useful for those who perform their own seasonal maintenance and want the correct replacement part without guesswork.

It is not intended for universal use across unrelated filter brands or for structural repairs beyond the tank seal.
