The construction bonds a cross-linked polyethylene core to an aluminum layer and a PE outer jacket, providing an integral oxygen barrier and excellent form stability. Rated to 160 psi and 200 degrees F, this tubing handles the pressure and temperature demands of residential and light-commercial heating applications. The aluminum layer allows the tubing to be bent by hand and hold its shape without a support fitting, making it a practical choice for exposed basement runs and baseboard connections. A licensed plumber or radiant heating installer is the typical trade professional for this product.\u003c\/p\u003e\n\u003cp\u003eVIEGA 35020 is designed for hydronic heating installations including radiant floor systems, baseboard heating loops, and mechanical room distribution manifolds. Its gray color and rigid-hold bend characteristic make it well-suited for exposed interior runs where neat, self-supporting routing is required. The tubing is compatible with Viega press fittings only and must not be used with crimp, clamp, or expansion-style PEX fittings. It meets NSF, ASTM F876, and ASTM F877 standards, confirming suitability for potable and heating system use where those certifications are required by local code.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePEX-AL-PEX three-layer construction provides a built-in oxygen barrier, reducing system corrosion in closed hydronic loops\u003c\/li\u003e\n  \u003cli\u003eRetains bent shape without support fittings, ideal for exposed basement and baseboard runs\u003c\/li\u003e\n  \u003cli\u003eRated to 160 psi and 200 degrees F for demanding hydronic heating service\u003c\/li\u003e\n  \u003cli\u003eCompatible with Viega press fittings only — not for use with crimp, clamp, or expansion tooling\u003c\/li\u003e\n  \u003cli\u003eMeets NSF, ASTM F876, and ASTM F877 standards\u003c\/li\u003e\n  \u003cli\u003eSupplied in a 150-foot coil for efficient handling on the job site\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Viega press fittings only.

Shut off and depressurize the system before cutting or connecting tubing. Use only Viega-approved press tooling and fittings — substituting other fitting types will void compatibility and may compromise system integrity. Minimum bend radius should be observed to avoid kinking; the aluminum layer holds bends but will not recover from a kink.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 150 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubing Type\u003c\/strong\u003e: PEX-AL-PEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PEX-AL-PEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Coil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Pressure\u003c\/strong\u003e: 160 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Temperature\u003c\/strong\u003e: 200 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Heating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting System Compatibility\u003c\/strong\u003e: PEX Press\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards Met\u003c\/strong\u003e: NSF, ASTM F876, ASTM F877\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 10 Year\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: VIEGA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 35020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VIEGA","offers":[{"title":"Default Title","offer_id":51268211278130,"sku":"35020","price":159.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308910916.jpg?v=1780701759","url":"https:\/\/voomisupply.com\/products\/viega-35020-pex-al-pex-tubing-0-5-inch-150-foot-coil","provider":"Voomi Supply","version":"1.0","type":"link"}
