If you have a leaking Pentair Leaf Trap or Rainbow Chlorinator, the Pentair R172223 O-Ring is the replacement gasket you need to fix the leak at your lid. You should see very slim cracks affecting flow in your equipment lid.
Who is this for?
Pool owners who notice a leak in their Pentair Rainbow or Leaf Trap systems, should check their equipment's lid assembly for cracks in the O-ring. Service technicians may even have this O-ring on hand as it replaces common Pentair equipment.
