W Cooper Hub w/Standpipe [RS-1615 No Laterals] (2016A) is a W. Cooper Industries hub with standpipe for compatible RS-1615 No Laterals filter assemblies. The hub and standpipe help direct water through the filter system and are key internal components in proper filtration performance. This replacement version is listed without laterals, making it useful when the standpipe or hub requires replacement but the matching lateral set is handled separately. Internal filter components should be matched carefully because height, hub configuration, and model compatibility affect how the filter distributes and collects water during operation. This part is intended for service work on compatible W. Cooper RS filter models and should be checked against the existing assembly before installation. Inspect laterals, seals, tank condition, and drain components during the repair to help avoid repeated disassembly. Hub and standpipe assembly for compatible W. Cooper filters Listed without laterals for targeted internal repairs Supports proper water distribution inside the filter Useful for worn, cracked, or damaged internal assemblies Confirm model series and configuration before ordering
