## Description

Review: Fit perfectly my Rainbow model 320 - The old ring had deteriorated with age and the local shops wanted more than I wanted to pay, this pack was at a great price and the ring dropped right in.
Review: Lid on chlorinator was getting harder and harder to remove ... - Lid on chlorinator was getting harder and harder to remove, discovered that the lid O-ring was swollen from the chlorine and it was time to replace. These TORK O-rings worked just perfectly. Fit precisely, and lid is now easier to remove. Will definitely order these again as needed. Arrived ahead of schedule in an appropriately sized package.
