Where This Part Is Used

In typical pool and spa circulation systems, this suction component is found in skimmer assemblies where suction is extracted from the surface, as well as in jet body assemblies that feed water toward the pump. It commonly appears on the pump suction side, between the pump and the filter, and in return-line paths where suction control is needed. You’ll also see it integrated into filter housings as part of the suction path feeding the filter. This part supports system operation by maintaining clear suction paths and reliable connections between components. In service scenarios, it helps ensure steady water flow and predictable pump performance.
