Pentair E21 2 Wall Fitting O-Ring Replacement Automatic Pool Cleaner

The replacement o-rings for pool fittings have generally garnered a mixed response from customers who have utilized them to combat common issues such as leaks and noises associated with aging o-rings. Many users found success with these replacements; for instance, one customer's experience involved replacing a worn-out o-ring, resulting in the elimination of a high-pitched whistling sound, much to their satisfaction and the happiness of their spouse. The product comes in a two-pack, which is perceived as convenient by some users who have experienced compatibility with various models, such as the Polaris and Kreepy Crawly II. Applying lubricant to the o-rings was suggested by several reviewers as a way to enhance longevity, which reflects a proactive approach for maintaining pool equipment. While many reviewers noted proper fit and effectiveness, there were notable complaints regarding price. Some customers expressed the sentiment that the o-rings felt overpriced, particularly when only one o-ring could be used if the other served as an immediate backup. Others reported sizing issues, wherein the o-rings did not fit tightly enough, resulting in dissatisfaction. Overall, while the replacement o-rings delivered functionality and efficiency in many cases, concerns around pricing and fit inConsistency reveal a level of fragmentation in customer satisfaction. **
