PEX-A is manufactured using the Engel (peroxide) method, which produces the highest degree of cross-linking among PEX types, resulting in superior flexibility and shape memory. The red color coding identifies this tubing as intended for hot-water lines, simplifying rough-in identification for plumbers and HVAC technicians during installation.\u003c\/p\u003e\n\u003cp\u003eThis tubing is appropriate for hydronic radiant floor heating, domestic hot water supply, and other closed-loop or open water distribution applications. Its flexibility allows it to be routed through framing, around obstacles, and into manifold systems with minimal fittings. The 20-foot length suits single-run drops or shorter branch circuits in residential manifold-based plumbing layouts. Licensed plumbers and hydronic heating contractors are the typical installers for this product type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePEX-A construction using the Engel method for maximum cross-link density and flexibility\u003c\/li\u003e\n  \u003cli\u003eRed color coding identifies hot-water service lines at a glance\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch CTS sizing is compatible with standard PEX expansion and crimp fitting systems\u003c\/li\u003e\n  \u003cli\u003e20-foot length provides a manageable single-coil run for branch or drop installations\u003c\/li\u003e\n  \u003cli\u003eHigh shape memory allows kinks to be repaired with a heat gun without cutting out the section\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flexible tubing solution for 1\/2-inch CTS PEX plumbing and radiant heating systems.

Shut off the water supply and relieve system pressure before making any connections. Use only fittings and tools rated for PEX-A tubing at the appropriate CTS size, and avoid over-bending beyond the minimum bend radius to prevent flow restriction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubing Type\u003c\/strong\u003e: PEX-A (Engel Method)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1\/2 inch CTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 20 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 813927011871\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrder Increment\u003c\/strong\u003e: 1\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: 21205A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51396412080434,"sku":"21205A","price":18.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834190.jpg?v=1782831330","url":"https:\/\/voomisupply.com\/products\/uponor-21205a-pex-a-tubing-0-5-inch-cts-red-20-foot","provider":"Voomi Supply","version":"1.0","type":"link"}
