Specifically designed to fit the tapered internal diverter rotor core of classic Pentair, Purex, and PacFab SM and SMBW 2000 and 4000 series side-mounted diatomaceous earth (D.E.) separation valves (including models like the 4024, 4036, and 4048), this premium gasket ensures airtight mechanical division between ports. When the manual control handle is depressed and rotated to shift operational modes, this specialized seal seats firmly within the valve body's machined channels to prevent high-velocity pressurized water from cross-contaminating plumbing lines or chronically weeping out of the backwash waste port during standard filtration cycles. Molded from a high-grade, premium-density elastomeric compound featuring an iconic red hue for easy field identification, the seal delivers exceptional dimensional compression memory, low surface friction, and advanced ozone resistance. This allows it to easily manage baseline operating pressures up to 50 PSI while withstanding continuous exposure to concentrated chlorine shock, salt-chlorine generation, and heavy pool mineral scaling without swelling, flattening, or dry-rotting. The physical dry weight of this single Pentair Red Tapered Rotor Seal is approximately \u003cb data-path-to-node=\"0\" data-index-in-node=\"1447\"\u003e0.15 pounds\u003c\/b\u003e (roughly 2.40 ounces, with a nominal packaged shipping weight of up to 0.25 pounds), providing pool service professionals and DIY homeowners with an essential, long-lasting hardware standard to maintain peak filtration efficiency and system pressure.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003e \u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53180363571311,"sku":"071720","price":36.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/513Lps20deL._AC_UF894_1000_QL80.jpg?v=1780415182","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-sm-and-smbw-red-tapered-valve-rotor-seal","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
