Pentair Tank Clamp Bolt

The Pentair Tank Clamp Bolt (part number 190035 or 190035Z) is a specialized, high-tensile structural fastener engineered exclusively for the heavy-duty plastic and stainless steel tensioning clamp bands that secure the split-tank chassis of Pentair Clean & Clear, Clean & Clear Plus, Predator, and FNS Plus pool and spa filtration systems. Machined from a premium, corrosion-resistant stainless steel alloy, this heavy-gauge threaded T-bolt features an integrated tee-head design at one end, allowing it to hook securely into the receiver slots of the interlocking clamp halves. Its primary structural role is to serve as the main mechanical anchor that draws the perimeter clamp band tight when the matching brass nut is torqued down, providing the massive, uniform compression load required to squeeze the main tank O-ring. This high-torque closure establishes an absolute airtight and watertight pressure boundary, enabling the large filtration vessel to safely contain continuous hydraulic operating pressures up to 50 PSI without weeping or experiencing dangerous lid separation. Built to be completely impervious to rust, oxidation, intense outdoor UV weathering, and continuous exposure to harsh pool chemistry like chlorine and acid washes, this critical safety bolt prevents catastrophic pressure failures under intense stress. Due to its solid, heavy-gauge stainless steel composition and elongated threaded shaft, this individual clamp bolt carries a net product and shipping weight of approximately 0.30 to 0.40 pounds (about 4.8 to 6.4 ounces).
