The 70 ft length with a 1\/2 in nominal size (about 12 mm inner diameter by 16 mm outer diameter) supports up to 100,000 BTU\/hour, making it suitable for larger patio grills, generators, water heaters, and ranges. The standout reason to buy is the combination of stainless SUS304 construction and a UV-resistant yellow polyethylene jacket that keeps the line corrosion-resistant and durable for indoor, outdoor, or buried runs.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength and size:\u003c\/strong\u003e The 70 ft length and 1\/2 in gas pipe size provide long runs without multiple joints, reducing potential leak points and labor time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow capacity:\u003c\/strong\u003e Rated to carry up to 100,000 BTU\/hour, it supplies sufficient airflow for larger appliances like grills and generators.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Inner corrugated tubing is stainless steel SUS304 for corrosion resistance, while the outer yellow jacket offers UV protection and visibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFittings:\u003c\/strong\u003e Each end comes with 1\/2 in male brass fittings and standard pipe threads for straightforward connections to existing supply lines and appliances.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexibility and installation:\u003c\/strong\u003e The corrugated design easily snakes around corners, through attics and basements, and can be cut to length to simplify routing in tight spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurability:\u003c\/strong\u003e The material is suitable for exposed installation, embedding in concrete, or burial, so it meets a variety of project needs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis product is aimed at DIYers, professional plumbers, and remodelers who need a long, continuous gas line run without installing many fittings.
