Each strip is about 4 meters (13 feet) long and comes in one of four common diameters (1\/4\", 3\/8\", 1\/2\", 5\/8\") so you can match the pipe to the system and avoid size mistakes. The included bender functionality helps keep tubing smooth and reduces the risk of kinks during installation, while color-coded sleeves speed identification when you’re working under time pressure.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this kit fit into typical air-conditioning installations?\u003c\/h3\u003e\n\u003cp\u003eThe Relaxweex kit is designed for extensions, on-site repairs, and custom routing of refrigerant lines. Because the tubing arrives in long continuous strips and with a bend-ready profile, it lets you measure, cut, and lay the line exactly where you need it.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFour common diameters to match system ports and fittings.\u003c\/li\u003e\n  \u003cli\u003e4 m length per strip for fewer joins and cleaner runs.\u003c\/li\u003e\n  \u003cli\u003eBuilt-in bending guide reduces need for extra tools.\u003c\/li\u003e\n  \u003cli\u003eColor-coded jackets for fast size checks on the job.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and protections are included to ensure durability?\u003c\/h3\u003e\n\u003cp\u003eEach copper tube is wrapped in a PET (polyethylene terephthalate) jacket that shields the metal from abrasion, UV exposure, and rough handling during installation.
