Pentair Pentek Dura-Series Standard Filter Housings deliver dependable whole-house filtration for residential, commercial, and industrial water. The polycarbonate sump significantly boosts durability for greater longevity, while an improved radial O-ring design and reinforced polypropylene cap provide a robust, leak-proof seal. This 10-inch housing is equipped with 3/4" NPT inlet and outlet ports and accepts a standard 10-inch drop-in filter cartridge, letting you tailor filtration to your water. An optional pressure-relief button on the cap bleeds internal pressure for fast, clean cartridge changes, and the cap is molded with locations for bracket mounting hardware. Rated to 125 psi maximum and 40 to 125 degrees F, Dura-Series housings are Tested and Certified by NSF International to NSF/ANSI Standard 42 for material and structural integrity. Bracket and cartridge are sold separately; guard against freezing to avoid cracking and water leakage.
