Constructed from high-impact, chemical-resistant thermoplastic, this compact male pipe thread (MPT) plug screws directly into the dedicated priming or drainage port of the pump housing. Its primary operational role is to facilitate the pre-priming process by letting operators fill the internal pumping chamber with water before ignition, while the included synthetic rubber O-ring compresses under hand-tightening to establish an absolute airtight, watertight seal. By sealing this crucial boundary, the assembly prevents hazardous vacuum drops or localized pressure leaks that would otherwise destabilize the pump’s hydraulic performance or damage its internal mechanical seals during operation.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eAs a highly compact plastic and rubber component, its weight footprint is minimal:\u003c\/p\u003e\n\u003cul data-path-to-node=\"2\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,0,0\" id=\"p-rc_0a516ce8a4380a7f-62\"\u003e\u003cspan class=\"citation-93\"\u003e\u003c\/span\u003e\u003cb data-path-to-node=\"2,0,0\" data-index-in-node=\"0\"\u003e\u003cspan class=\"citation-93\"\u003eActual Product Weight:\u003c\/span\u003e\u003c\/b\u003e\u003cspan class=\"citation-93\"\u003e Approximately \u003c\/span\u003e\u003cb data-path-to-node=\"2,0,0\" data-index-in-node=\"37\"\u003e\u003cspan class=\"citation-93\"\u003e0.02 pounds\u003c\/span\u003e\u003c\/b\u003e\u003cspan class=\"citation-93 citation-end-93\"\u003e (roughly 0.32 ounces).\u003csup class=\"superscript\" data-turn-source-index=\"1\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e \u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"2,1,0\"\u003e\u003cb data-path-to-node=\"2,1,0\" data-index-in-node=\"0\"\u003ePackaged Shipping Weight:\u003c\/b\u003e Typically scales at \u003cb data-path-to-node=\"2,1,0\" data-index-in-node=\"46\"\u003e0.10 to 0.20 pounds\u003c\/b\u003e due to the protective parts padding or standard bubble-mailer envelope used during transit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53762600927343,"sku":"U178-940P","price":11.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/s-l500__49763_186df3bf-ad04-4346-a26e-3dede0bed26f.jpg?v=1783608202","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-utility-pump-fill-plug-and-o-ring-assembly","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
