Pentair Elbow and Baffle Bulkhead Assembly

The Pentair Elbow and Baffle Bulkhead Assembly (part number 190030Z or 190030) is a critical internal plumbing and water-distribution kit engineered for a wide array of Pentair cartridge and D.E. filtration systems, including the Clean & Clear Plus, FNS Plus, and Quad D.E. series. Injection-molded from a heavy-walled, high-impact, and chemical-resistant polymer composite, this multi-piece assembly features a curved structural elbow coupled with a specialized deflector baffle and matching bulkhead connection threads. Its primary structural and functional role is to bridge the lower filter tank wall, anchoring the internal plumbing manifold directly to the external return lines. As filtered water exits the grid or cartridge core, the integrated baffle diffuses the high-velocity hydraulic stream, reducing internal turbulence and preventing high-pressure water from hammering the filter elements. Built to withstand continuous system operating pressures up to 50 PSI, forceful pump surges, and a constant flow of heavily chlorinated pool water or acid washes, this durable assembly eliminates pressure bypass leaks and external weeping at the tank's lower ports. Due to its thick-walled, heavy-duty thermoplastic architecture designed to endure long-term structural stress, the complete elbow and baffle bulkhead assembly carries an individual product and shipping weight of approximately 0.95 pounds (about 15.2 ounces).
