When the release module is activated -- whether manually or via thermal detection -- it punctures a nitrogen cartridge and sends a high-pressure pneumatic signal through this tubing to the agent cylinder valves. Any restriction, kink, or leak in this line can delay or prevent the signal from reaching the cylinders, resulting in a failure to discharge.\u003c\/p\u003e\n        \u003cp\u003eThe 22278 is not standard refrigeration-grade copper. Its 0.049-inch wall thickness is specifically engineered and UL listed to contain the instantaneous pressure surges of 1,800 PSI or more that occur during system actuation without ballooning or splitting. Standard copper tubing may appear identical but does not meet UL 300 wall thickness requirements, and its use voids the system's UL listing. Using genuine Amerex OEM tubing is a requirement for maintaining system compliance.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 2: Technical Specifications --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eTechnical Specifications\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003ctable class=\"specs-table\"\u003e\n          \u003cthead\u003e\n            \u003ctr\u003e\n              \u003cth\u003eFeature\u003c\/th\u003e\n              \u003cth\u003eDetails\u003c\/th\u003e\n            \u003c\/tr\u003e\n          \u003c\/thead\u003e\n          \u003ctbody\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eManufacturer\u003c\/td\u003e\n              \u003ctd\u003eAmerex Corporation\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003ePart Number\u003c\/td\u003e\n              \u003ctd\u003e22278\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eLength\u003c\/td\u003e\n              \u003ctd\u003e50 feet (coiled)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eOutside Diameter\u003c\/td\u003e\n              \u003ctd\u003e1\/4\" (6.35 mm)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eWall Thickness\u003c\/td\u003e\n              \u003ctd\u003e0.049\" (1.24 mm)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eMaterial\u003c\/td\u003e\n              \u003ctd\u003eHigh-quality seamless copper\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eCompatibility\u003c\/td\u003e\n              \u003ctd\u003eAmerex KP (Kitchen) and IS (Industrial)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eCertification\u003c\/td\u003e\n              \u003ctd\u003eUL Listed, OEM Original\u003c\/td\u003e\n            \u003c\/tr\u003e\n          \u003c\/tbody\u003e\n        \u003c\/table\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 3: Installation \u0026 Compliance --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eInstallation \u0026amp; Compliance\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003ch3\u003ePrecision Bending -- No Kinks\u003c\/h3\u003e\n        \u003cp\u003eAll bends must be made with a professional mechanical tubing bender.
