Pentek R50 Pleated Polyester Sediment Filter Cartridge, 50 Micron, 9.75" (item #155038-43)

The Pentek R50 (Item #155038-43) is a 9.75" pleated polyester cartridge with a 50-micron nominal rating, built to capture coarser sediment such as sand, rust flakes, and scale particles in standard #10 filter housings. Its non-woven polyester media is pleated around a polypropylene core for durability, offering strong dirt-holding capacity while maintaining low pressure drop. The R50 is fully reusable — simply rinse and reinstall — and its bacteria- and chemical-resistant construction suits residential, commercial, and industrial water systems alike.
