PEX-a offers superior flexibility and shape memory compared to PEX-b or PEX-c alternatives, making it well suited for potable water distribution and hydronic heating applications. Each section measures 20 feet in length with an inside diameter of 0.862 inches and an outside diameter of 1.125 inches. The domestic origin and Engel-process crosslinking are key quality indicators for specifying engineers and licensed plumbers working on residential and light commercial systems.\u003c\/p\u003e\n\u003cp\u003eThis tubing is used in residential and light commercial potable water supply lines, hot and cold distribution systems, and radiant floor heating or hydronic panel systems. The straight 20-foot stick format is preferred on job sites where coil memory would complicate installation in tight mechanical rooms or when running longer straight runs through framed walls and joists. The white and red color coding helps tradespeople quickly identify hot and cold lines during rough-in.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEngel process PEX-a crosslinking provides high flexibility and coil-set recovery\u003c\/li\u003e\n  \u003cli\u003e1-inch nominal size with 0.862-inch inside diameter and 1.125-inch outside diameter\u003c\/li\u003e\n  \u003cli\u003e20-foot straight length reduces coil memory issues on long or straight runs\u003c\/li\u003e\n  \u003cli\u003eCrosslinked polyethylene construction resists scale, corrosion, and chlorine degradation\u003c\/li\u003e\n  \u003cli\u003eWhite and red color coding supports hot and cold line identification during rough-in\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured tubing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Uponor AquaPEX expansion-style fittings and tools sized for 1-inch nominal PEX-a tubing.

Shut off the water supply and relieve system pressure before cutting into any existing line. Use only expansion or crimp tooling rated for 1-inch PEX-a; do not use open-flame tools near installed tubing. Support spacing, bend radius limits, and burial requirements must comply with the authority having jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.862 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 20 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Crosslinked Polyethylene (PEX-a)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturing Process\u003c\/strong\u003e: Engel Process\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White with Red Marking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: UPONOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: F4921000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51524513956146,"sku":"PIPERP1-20","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd3387f9bed301f3f47363f6bfe7676d.jpg?v=1785450464","url":"https:\/\/voomisupply.com\/products\/uponor-f4921000-aquapex-straight-tubing-1-in-20-ft-pex-a","provider":"Voomi Supply","version":"1.0","type":"link"}
