Pentair Clean & Clear Plus Cartridge Filters: CCP240, CCP320, CCP420, CCP520 Models: 180008, 160340, 160301 Hardware Physical Specifications: - Component: Tension Control Clamp Total Assembly - Material: High-Strength Stainless Steel Band - Included Parts: Clamp, Spring, Barrel Nut, Washers - Application: Upper and Lower Tank Flange Compression Technical Restoration Characteristics: The AUTOTOP 190003 clamp addresses common structural failures in aged filter housings, such as metal fatigue or corrosion of the fastening hardware. By providing consistent circumferential pressure around the tank flange, it ensures the mechanical coordination required to maintain a secure hydraulic seal during system operation. Mandatory Safety & Installation Advisory: High-pressure water systems pose a significant risk of physical injury if hardware is incorrectly installed. Always turn off the pump and open the air relief valve to release all internal tank pressure before removing or installing the clamp. During installation, tap the outside of the clamp with a rubber mallet while tightening the nut to ensure the band seats evenly. Do not over-torque the spring beyond the manufacturer's specified coil gap. Cross-Reference OE List: 190003, 190003Z, 180008, 160340, 160301, 77707-0001
