Pentair Complete Clamp Band

The Pentair Complete Clamp Band Assembly (part number 190003 or 190003Z) is a critical high-tension safety containment component stamped from heavy-gauge, marine-grade 300-series stainless steel, engineered exclusively for split-tank pool and spa filtration vessels across Pentair’s premium product lines, including Clean & Clear Plus cartridge, FNS Plus Diatomaceous Earth (D.E.), and Quad D.E. systems. The assembly features a unified hardware kit consisting of a high-tensile steel T-bolt, a heavy-duty barrel nut, a brass washer, and a specialized tension-control spring loop, all mounted onto a wide-diameter dual-hemisphere compression ring. Its primary operational role is to act as the absolute mechanical pressure-retention boundary for the split-tank chassis; when placed around the tank perimeter, its inner V-groove channel draws the upper lid and lower basin mating flanges together to compress the main body O-ring with uniform radial force. This establishes an absolute watertight compression seal that enables the large-format vessel to safely withstand continuous internal system operating pressures up to 50 PSI, serving as a primary safety shield against catastrophic lid separation under severe pump startup surges and intense hydraulic vibration. Engineered to survive decades of demanding outdoor equipment pad weathering, its rugged stainless steel band and heavy hardware completely resist structural stretching, tensile fatigue, advanced rusting, and corrosive degradation from direct contact with pool chemical vapors and highly concentrated sanitizers like chlorine or bromine. Due to its thick-gauge metal band geometry and integrated heavy-duty steel spring bolt hardware, this complete tension clamp assembly carries a net product and shipping weight of approximately 5.50 to 6.25 pounds (about 88.0 to 100.0 ounces).
