The product injects into closed systems using a standard manifold gauge or Leak Shot Injection Kit, is formulated to circulate safely with system oil, and works across a wide range of refrigerants and equipment types (excluding ammonia systems).\u003c\/p\u003e\n\n\u003ch3\u003eHow does this sealer actually stop small refrigerant leaks?\u003c\/h3\u003e\n\u003cp\u003eWhen Leak Saver encounters air and moisture at a leak site, its active ingredients quickly react to form a durable plug that blocks the escape path.

Leak Saver Direct Inject UV is intended for HVAC professionals, refrigeration technicians, and experienced DIYers who need a rapid, low-fuss option to repair minor refrigerant leaks or to accelerate leak diagnostics on larger failures. If you handle system service with a manifold gauge or injection kit and want a product that both attempts permanent sealing and aids visual leak finding, this three-pack offers convenience, compatibility across refrigerants, and UV visibility to speed repairs. For large-scale or highly pressurized losses, plan for proper mechanical repair or component replacement after using the dye for detection.\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: Can I use Leak Saver Direct Inject UV in my car’s A\/C?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it works in automotive systems but requires the R134a to 1\/4\" charging adapter for proper injection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will the UV dye interfere with system operation?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — the additive is intended only for leak detection and circulates without affecting normal system performance.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Leak Saver","offers":[{"title":"Default Title","offer_id":48082731565214,"sku":"B077Y2XLDR","price":162.43,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/leak-saver-direct-inject-uv-front-packaging.jpg?v=1785812444","url":"https:\/\/northtrailauto.ca\/products\/leak-saver-direct-inject-uv-refrigerant-leak-sealer-3-pack-uv-dye-for-leak-detection-works-with-all-common-refrigerants-fits-u","provider":"North Trail Auto","version":"1.0","type":"link"}
