This replacement cap assembly is a standard hardware component across legacy and contemporary Sta-Rite and Pentair lines, including the Sta-Rite PXC, PRC, and PRD modular media cartridge filter series.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eInjection-molded from a dense, high-impact, and chemically inert polymer compound, this compact closure cap features a standardized 3\/4-inch Garden Hose Thread (GHT) profile. Its primary operational role is to completely seal off the lower gravity drain port located at the base of the filter tank chassis. When threaded hand-tight over the drain spigot, the included resilient elastomeric sealing washer or gasket compresses uniformly within the cap crown. This establishes an absolute watertight and airtight compression boundary, ensuring the pressurized filter vessel can safely contain its internal hydraulic volume while sustaining standard operating pressures up to 50 PSI without weeping, leaking, or backing out under pump vibration surges.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eDuring seasonal winterization, routine cartridge cleaning, or media changeouts, the cap can be easily unthreaded without tools. This allows operators to cleanly evacuate stagnant water from the lowest point of the tank core, preventing structural freeze-cracking of the outer composite shell during sub-zero temperatures. Because it uses a standard 3\/4-inch hose thread pattern, the filter's drain spigot can alternatively accept a standard garden hose when the cap is removed, allowing technicians to direct chemical-laden rinse water away from the equipment pad.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003eEngineered to endure a lifetime of demanding outdoor equipment pad weathering, intense seasonal temperature shifts, and direct UV exposure, its rugged composite framework completely resists material softening, structural deformation, and corrosive breakdown from chemical splashing or direct contact with pool sanitizers like chlorine and bromine. Due to its ultra-compact, hollow plastic profile, this individual drain cap assembly with its internal sealing washer carries a nominal product and shipping weight of approximately \u003cb data-path-to-node=\"3\" data-index-in-node=\"529\"\u003e0.05 to 0.08 pounds\u003c\/b\u003e (about 0.80 to 1.28 ounces).\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53416218853487,"sku":"32185-7074","price":12.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/149650025__01493_d74c3343-2aa0-4eb0-b135-95130b351cf1.jpg?v=1782745876","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-3-4-threaded-drain-capp-assembly-with-washer","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
