The Pentair WhisperFlo Pump Lid O-Ring (350013Z) is a replacement strainer lid o-ring for Pentair WhisperFlo (WF, WFE, WFK, WFDS) series pool pumps. This o-ring seals the clear str ainer lid to the pump strainer body, preventing air from being drawn into the pump suction side during operation. A deteriorated lid o-ring causes air bubbles in the return lines, loss of prime, and reduced pump performance. Replace this o-ring routinely whenever the strainer lid is removed for basket cleaning -- it is an inexpensive part that prevents costly pump service calls.SKU: 350013Z Show more
