Supplied in a 1200-foot coil with a 3\/8-inch outer diameter, this black tubing with stripe is manufactured from cross-linked polyethylene (PEX-B) and includes an oxygen barrier layer. The barrier construction inhibits oxygen diffusion into the system, which helps protect ferrous components such as boiler heat exchangers, circulators, and manifold assemblies from corrosion over time. Licensed plumbers and hydronic heating technicians are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThis tubing is intended for residential and light commercial radiant floor heating applications. It is routed through or beneath flooring assemblies — including staple-up, thin-slab, and below-subfloor configurations — and connected to manifold distribution systems. The 3\/8-inch diameter is well-suited for shorter loop runs where lower flow resistance is acceptable and finer zoning control is desired. The 1200-foot coil length reduces the number of splices needed on larger installations, making it practical for multi-loop radiant layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOxygen barrier layer reduces corrosion risk to ferrous system components\u003c\/li\u003e\n  \u003cli\u003ePEX-B material provides flexibility and resistance to scale and chlorine degradation\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch diameter suitable for shorter radiant loop runs and fine zoning applications\u003c\/li\u003e\n  \u003cli\u003e1200-foot continuous coil minimizes field splices on large radiant installations\u003c\/li\u003e\n  \u003cli\u003eBlack with stripe color aids loop identification during installation and service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation radiant tubing for residential and light commercial hydronic heating systems that require barrier PEX-B tubing in 3\/8-inch diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or hydronic heating technician in accordance with local mechanical and plumbing codes. Shut down and depressurize the hydronic system before making any connections to existing piping. Use only fittings and tools rated and listed for PEX-B tubing to ensure leak-free joints. Avoid kinking the tubing during layout; use a pipe bending support or coil unroller to maintain minimum bend radius throughout the installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Length\u003c\/strong\u003e: 1200 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Material\u003c\/strong\u003e: PEX-B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Radiant Tubing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black with Stripe\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: 11418\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VIEGA","offers":[{"title":"Default Title","offer_id":51233543782706,"sku":"11418","price":962.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307633925.jpg?v=1780102720","url":"https:\/\/voomisupply.com\/products\/viega-11418-pex-b-radiant-tubing-3-8-in-x-1200-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
