Pentair 5" Baffle and Bulkhead Fitting

The Pentair 5" Baffle and Bulkhead Fitting (part number 190030 or 190030Z) is a specialized internal fluid-dynamics and plumbing connection assembly designed specifically for high-capacity Pentair Clean & Clear Plus cartridge filters and Quad D.E. pool and spa filtration systems. Injection-molded from a thick-walled, high-impact, and UV-stabilized polymer composite, this structural fitting features an integrated 5-inch wide deflection baffle plate mated to a heavy-duty threaded bulkhead shaft. Its primary operational role is twofold: it serves as the secure physical bridge that passes through the composite filter tank shell to connect external pool piping, while internally intercepting the raw, high-velocity stream of incoming water. By deflecting and diffusing the turbulent hydraulic flow smoothly around the lower perimeter of the vessel, it prevents the water from blasting directly onto the delicate fabric pleats of the internal filter cartridges or D.E. grids, ensuring an even distribution across the media surface and preventing premature tearing or erosion under continuous operating pressures up to 50 PSI. Built to endure constant submersion in highly concentrated sanitizing chemicals like chlorine, bromine, and seasonal acid washes, its robust plastic architecture resists cracking under long-term mechanical stress and pump vibration surges. Due to its multi-dimensional, thick-walled construction designed to handle expansive commercial and residential flow rates, this individual baffle and bulkhead fitting assembly carries a net product and shipping weight of approximately 0.65 to 0.80 pounds (about 10.4 to 12.8 ounces).
