The Rossesay AC Flush Kit is built for auto technicians, HVAC service professionals and experienced DIYers who perform system maintenance or component replacements and need a durable, reusable flush canister with pressure readout. It’s especially useful when replacing compressors, retrofitting refrigerants, or recovering systems after oil contamination. Always follow solvent safety guidelines, wear protective equipment, and use a separate air compressor and compatible flush solvent as required by your shop procedures.\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 flush with refrigerant instead of solvent in this canister?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Use a compatible low-viscosity solvent only.
