PEX-A is manufactured using the Engel method, which produces the highest degree of cross-linking among PEX types, giving the tubing superior flexibility and the ability to expand for fitting connections. The red color coding indicates hot-side service, making it easy to distinguish supply lines during rough-in. Licensed plumbers and hydronic installers use this tubing for potable water distribution, radiant heating systems, and in-wall domestic water piping.\u003c\/p\u003e\u003cp\u003eThis tubing is suited for residential and light commercial plumbing and hydronic applications. The 1\/2-inch CTS size is the most common diameter used in branch runs from manifolds to fixtures in PEX distribution systems. Its flexibility allows it to navigate framing cavities with minimal fittings, reducing potential leak points. Typical installations include hot water branch lines from a manifold, under-slab radiant loops, and baseboard heating connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePEX-A material produced by the Engel method for maximum cross-link density and flexibility\u003c\/li\u003e\n\u003cli\u003e1\/2-inch CTS sizing matches standard copper tube size for direct compatibility with PEX expansion fittings and crimp rings\u003c\/li\u003e\n\u003cli\u003eRed color coding identifies hot-side or supply-side runs at a glance\u003c\/li\u003e\n\u003cli\u003e100-foot roll provides enough continuous length for most single-zone or multi-branch rough-in jobs\u003c\/li\u003e\n\u003cli\u003eFlexible enough to bend without kinking at typical installation temperatures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation tubing for residential and light commercial PEX-A plumbing and hydronic systems using 1\/2-inch CTS expansion or crimp fittings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of PEX-A tubing should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and local amendments. Shut off the water supply and depressurize the system before cutting into any existing lines. Use the appropriate PEX expansion tool or crimp tool rated for the fitting system being used. Avoid routing tubing in areas with direct UV exposure, as PEX is not rated for outdoor sunlight exposure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eRoll Length\u003c\/strong\u003e: 100 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 813927011819\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrder Increment\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 21105A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51396259250482,"sku":"21105A","price":60.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834186.jpg?v=1782828422","url":"https:\/\/voomisupply.com\/products\/uponor-21105a-pex-a-tubing-0-5-in-cts-red-100-ft-roll","provider":"Voomi Supply","version":"1.0","type":"link"}
