With an inside diameter of 0.671 inches and an outside diameter of 0.875 inches, this white and blue marked tubing delivers the flexibility and memory characteristics that PEX-a is known for in hot and cold potable water distribution and hydronic radiant heating systems. Licensed plumbers and mechanical contractors select this product for its conformance to domestic manufacturing standards and its compatibility with Uponor expansion-style fittings.\u003c\/p\u003e\n\u003cp\u003eThis tubing is suited for residential and light commercial plumbing rough-in, manifold-based home-run distribution systems, and hydronic radiant floor or wall heating loops. The 100-foot coil length makes it practical for longer branch runs or radiant loop installations where a single continuous length reduces fittings and potential leak points. The dual white and blue color marking helps installers distinguish cold-water or return lines at rough-in and inspection stages.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePEX-a classification via Engel process for superior flexibility and shape memory\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch nominal size with 0.671-inch inside diameter and 0.875-inch outside diameter\u003c\/li\u003e\n  \u003cli\u003e100-foot continuous coil minimizes in-line fittings on long runs\u003c\/li\u003e\n  \u003cli\u003eCrosslinked polyethylene construction resists scale, corrosion, and freeze damage\u003c\/li\u003e\n  \u003cli\u003eWhite and blue color marking aids cold-water and return-line identification\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Uponor expansion-style PEX-a fittings and rings in potable water distribution and hydronic radiant heating applications where 3\/4-inch nominal PEX-a tubing is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or mechanical contractor in accordance with local plumbing codes and ASTM F876\/F877 standards. Shut off the water supply and depressurize the system before cutting into any existing lines. PEX-a expansion fittings require a compatible expansion tool sized for 3\/4-inch; do not use crimp or clamp fittings intended for PEX-b or PEX-c with this tubing. Maintain minimum bend-radius requirements and protect tubing from prolonged UV exposure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.671 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 100 ft\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 Blue Marking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\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: F4340750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51525226299698,"sku":"PIPEBP34-100","price":111.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a173f24baba1c4c3a6102599ee66fd8_6bcb5343-bd13-420c-bdc4-851344293166.jpg?v=1785467804","url":"https:\/\/voomisupply.com\/products\/uponor-f4340750-aquapex-pex-a-tubing-3-4-in-100-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
