The tubing's corrugated stainless steel core and yellow UV-resistant jacket make it a practical, flexible alternative to rigid pipe when routing through attics, basements, or around obstacles.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e100ft length:\u003c\/strong\u003e Provides a long continuous run so fewer joints are needed and installations across larger distances are simpler.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/4' bore capacity:\u003c\/strong\u003e The 0.63' inner diameter supports up to 150,000 BTU\/hour, suitable for larger appliances and combined loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrugated stainless core:\u003c\/strong\u003e Made from SUS304 stainless steel for corrosion resistance and reliable flow inside the tubing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible installation:\u003c\/strong\u003e The corrugated design allows the line to be cut to length and to snake around corners, reducing the need for extra fittings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV-resistant jacket:\u003c\/strong\u003e The 0.079' yellow polyethylene jacket resists sunlight exposure when routed in exposed spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-piece construction:\u003c\/strong\u003e The single molded body reduces intermediate interfaces, lowering potential leak points when installed correctly.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis product is aimed at DIYers, builders, and HVAC or plumbing professionals who need a long flexible gas supply line for natural gas or propane applications such as grills, fire pits, ranges, or water heaters.
