{"product_id":"roth-multipex-tg-r-i-r-18-mm","title":"Roth MultiPex TG Pipe-in-Pipe 18 mm, 60 m","description":"\u003cp\u003eThe Roth MultiPex TG 18 mm pipe-in-pipe system is a highly flexible, corrosion-resistant combi PEX solution designed for both central heating and domestic potable water installations. Encased in a 28 mm protective conduit and supplied in a 60-meter continuous coil, it delivers reliable, leak-secure routing in new builds and renovations.\u003c\/p\u003e\n\u003cp\u003eThe Roth MultiPex TG pipe-in-pipe system is engineered to provide a robust and versatile piping solution suitable for both domestic drinking water and hydronic central heating systems. Built using durable plastic materials, the inner PEX pipe offers long-lasting performance and complete resistance to scaling, pitting, and corrosion, ensuring clean water transport and optimal thermal flow.\u003c\/p\u003e\n\u003cp\u003eSupplied inside an outer 28 mm corrugated conduit, the pipe-in-pipe configuration provides critical protection against mechanical impact and structural friction. The conduit system also enables damage-free replacement of the inner service pipe if necessary, while effectively channeling any accidental leaks safely away from hidden construction cavities.\u003c\/p\u003e\n\u003cp\u003eEngineered for demanding residential and commercial environments, the pipe is rated for a continuous operating pressure of PN 10 (10 bar) and operating temperatures up to 70°C. For added safety and resilience against thermal fluctuations, it can also withstand short-term peak temperatures reaching up to 95°C without compromising structural integrity.\u003c\/p\u003e\n\u003cp\u003eInstallation is streamlined by the pipe's exceptional flexibility and tight minimum bending radius of just 5 times its diameter. This compact bend radius makes navigating corners, joists, and tight utility spaces simple and efficient, reducing installation time and the need for excessive directional fittings.\u003c\/p\u003e\n\u003cp\u003eDelivered in a generous 60-meter continuous coil, the Roth MultiPex TG ensures comprehensive coverage across extensive layouts. Continuous runs significantly reduce the number of concealed joints within floors and walls, maximizing operational reliability and minimizing potential leakage points throughout the system.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Type: Pipe-in-Pipe (Combi PEX)\u003c\/li\u003e\n\u003cli\u003eInner Pipe Diameter: 18 mm\u003c\/li\u003e\n\u003cli\u003eOuter Conduit Diameter: 28 mm\u003c\/li\u003e\n\u003cli\u003eLength: 60 m\u003c\/li\u003e\n\u003cli\u003eMaterial: Cross-linked Polyethylene (PEX)\u003c\/li\u003e\n\u003cli\u003ePressure Rating: PN 10 (10 bar)\u003c\/li\u003e\n\u003cli\u003eMax Operating Temperature: 70°C\u003c\/li\u003e\n\u003cli\u003ePeak Temperature: Up to 95°C (short-term)\u003c\/li\u003e\n\u003cli\u003eBending Radius: 5 x pipe diameter\u003c\/li\u003e\n\u003cli\u003eApplications: Domestic potable water and central heating\u003c\/li\u003e\n\u003cli\u003eCorrosion Resistance: Non-corrosive plastic construction\u003c\/li\u003e\n\u003cli\u003eInsulation: Uninsulated\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Roth","offers":[{"title":"A - Like New","offer_id":63273386344778,"sku":"17087358.241-A","price":339.9,"currency_code":"EUR","in_stock":true},{"title":"B - Very Good","offer_id":63273386377546,"sku":"17087358.241-B","price":339.9,"currency_code":"EUR","in_stock":false},{"title":"C - Minor Wear","offer_id":63273386410314,"sku":"17087358.241-C","price":339.9,"currency_code":"EUR","in_stock":false},{"title":"D - Major Wear","offer_id":63273386443082,"sku":"17087358.241-D","price":339.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/3206\/8938\/files\/1722039_e4fee596-9799-48ac-9b04-4df3402b92b1.jpg?v=1792740281","url":"https:\/\/re.now\/products\/roth-multipex-tg-r-i-r-18-mm","provider":"Renow","version":"1.0","type":"link"}
