Pentair Clean & Clear Plus/FNS Plus/Quad D.E. Tank Clamp Kit

The Pentair Clean & Clear Plus/FNS Plus/Quad D.E. Tank Clamp Kit (part number 190003) is a vital, high-strength safety mechanism designed to unify and seal the upper and lower halves of larger Pentair pool and spa filter shells. This heavy-duty assembly features a thick, dual-segment stainless steel tension band engineered to tolerate intense, continuous hydraulic stress without warping. The comprehensive kit comes equipped with specialized tension control hardware—including a heavy-duty compression spring, flat washer, and a brass barrel nut—which ensures uniform compression is evenly distributed across the main tank O-ring to prevent catastrophic pressure blowouts during pump operation. Built to resist corrosion, rust, and harsh outdoor environments, the substantial metal band and its dedicated locking hardware carry an actual product weight of approximately 7.35 pounds (with a shipping weight of around 8.5 to 9.0 pounds), providing the robust, industrial-grade mass necessary to safely lock down high-pressure filtration systems.
