Built to match common interchange numbers (19194702, 15-34058, 76003), the kit lets you splice two line ends together using durable copper, aluminum and rubber components. It’s intended for DIY installation with minimal tools and can reduce downtime and replacement cost compared with swapping the whole hose or tube.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the usvehj splice connector repair a 5\/16\" aluminum A\/C line?\u003c\/h3\u003e\n\u003cp\u003eThe kit uses a sleeve-and-seal approach to join two exposed aluminum line ends and recreate a pressure-tight path for refrigerant.

Choose this kit when the damage is limited to a short section of tubing, you want to avoid the time and expense of replacing an entire line assembly, and you have basic hand tools and familiarity with safe A\/C service procedures. If your system has multiple damaged areas or component failures, a full-line replacement and certified A\/C service may be more appropriate.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this splice connector compatible with my 5\/16\" aluminum A\/C line?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—it's designed for 5\/16\" aluminum lines and lists interchange numbers 19194702, 15-34058, 76003 for broad compatibility.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need special tools to install the repair kit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No special tools are required; a screwdriver, tubing cutter, and deburring tool are typically all you need.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"usvehj","offers":[{"title":"Default Title","offer_id":48084490616990,"sku":"B09N92M912","price":29.75,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/usvehj-splice-connector-front-package.jpg?v=1785857128","url":"https:\/\/northtrailauto.ca\/products\/usvehj-5-16-air-conditioning-splice-connector-universal-800-643-repair-kit-for-aluminum-a-c-lines-corrosion-resistant-coupling","provider":"North Trail Auto","version":"1.0","type":"link"}
