Specifically designed to clamp the lower flange of a 1.5-inch top-mount multiport backwash valve securely to the upper tank lip of Pentair Cristall-Flo™ series sand filters, this heavy-duty, two-piece split-ring collar acts as the critical mechanical anchor for the entire pressure-side water loop. Injection-molded from a thick-walled, ultra-high-impact engineering polymer composite, the clamp halves encase the valve-to-tank junction and are tightened via robust zinc-plated or stainless steel hardware to distribute mechanical compression evenly across the primary sealing o-ring. This heavy-duty structural ring safely manages continuous operating line pressures up to 50 PSI, completely eliminating localized water weeping and preventing catastrophic blowouts caused by sudden pump startup surges. Its non-corrosive polymer matrix provides permanent resistance to advanced UV degradation, heavy winterizing thermal stresses, and continuous exposure to aggressive pool chemistry like chlorine shock or salt-chlorine generation without cracking or warping.
