Pentair SD/TA/TR 6-11/16" Lateral

The Pentair SD/TA/TR 6-11/16" Lateral Assembly (part number 152290 or 152290Z) is a precision-engineered internal distribution component designed specifically for Pentair Sand Dollar (SD40/SD60), Tagelus (TA40/TA60), and Triton series pool and spa sand filtration systems. Injection-molded from a high-grade, corrosion-resistant almond polymer composite, this 6-11/16 inch slotted finger component features a standard threaded or snap-on interface at its base to lock seamlessly into the central collection hub at the absolute bottom of the filter tank. Its primary functional role is to facilitate efficient backwashing and balanced water collection; the micro-slots spanning its surface are narrow enough to block dense silica sand or glass media from migrating out into the pool while allowing fully clarified water to pass through into the internal piping. Operating beneath hundreds of pounds of dense media, it is structurally engineered to withstand continuous hydraulic operating pressures up to 50 PSI, forceful flow reversals, and prolonged exposure to chemicals like chlorine, bromine, and winterizing acid treatments. Because of its hollow, streamlined plastic architecture, the individual lateral component is highly compact and carries a nominal product and shipping weight of approximately 0.12 pounds (about 1.9 ounces).
