Pentek St Series Stainless Steel Filter Housing

Supply the Pentek ST Series when plastic housings can't handle the heat or pressure. Built from brushed 304 stainless steel with a nickel-plated cast-brass head, this heavy-duty housing is designed for hot water and high-pressure point-of-use applications across commercial and industrial settings such as restaurants, spas, farms, schools, and institutions. Available as the ST-1 (10", up to 10 GPM) and ST-2 (20", up to 15-20 GPM), it accepts a complete range of standard double open end (DOE) cartridges up to 3" diameter. The 3/4" NPT sump has either a pipe plug or petcock for draining, and Buna-N and cellulose fiber gaskets provide the seal. Rated up to 250 psi and 275-300F depending on configuration. Not recommended for water with TDS or chlorides above 1000 ppm or pH below 5.0. A premium, high-durability option for dealers serving customers who need filtration beyond what standard polypropylene housings can support.
