About FJC Inc.
FJC Inc. — formally known in the trade as FJC Air Conditioning Products — is a manufacturer and nationwide distributor of automotive air conditioning parts and service accessories. With over 25 years of experience serving both the aftermarket and original equipment segments, FJC has established itself as one of the most trusted names in mobile A/C service in the United States.
Based in Mooresville, NC, FJC's product development philosophy centers on quality, environmental responsibility, and practical utility for the professional technician and serious DIYer alike. Their broad catalog covers everything a shop needs to diagnose, service, and restore a vehicle's air conditioning system — from chemical solutions to precision hand tools and gauges.
A/C System Flush & Fluids
One of FJC's signature strengths is its line of A/C System Flush products. FJC's flush solutions — including its well-known Extreme Klean and Kwik Klean formulas — are designed to remove moisture, acid, and contaminants from A/C systems, and are compatible with R-12, R-134a, and blended refrigerants. Critically, all FJC flushing solutions are environmentally safe, biodegradable, non-hazardous, and non-toxic, making them a responsible choice for shop use.
Complementing those solutions is FJC's dedicated line of Cooling System Flush Gun Kits. FJC's flush gun (part #2710) is the purpose-built delivery tool for their flush fluids, enabling technicians to precisely direct cleaning agents through A/C and cooling system components for thorough, efficient service.
Refrigerant Oils & Service Chemicals
FJC manufactures a comprehensive selection of Refrigerant Oil, including PAG oils, ester oils, and synthetic blends formulated to match OEM requirements across a wide range of vehicles. FJC provides cross-reference data with OE and FJC part numbers, oil types, and viscosity ratings, making it easier for technicians to select the right lubricant for every compressor. Like the rest of FJC's fluid lineup, these oils are formulated to protect compressor internals and extend system life.
A/C Repair Tools
FJC's extensive catalog of A/C Repair Tools spans everything from manifold gauge sets and vacuum pumps to valve core removers, nitrogen pressure testers, and refrigerant can taps. Their manifold gauge sets are available for R-134a and R-1234yf systems, with color-coded hoses and impact-resistant lenses for ease of use in busy shop environments. Whether you're performing a full system evacuation or a targeted pressure test, FJC has a purpose-built tool for the task.
Power Division: Inverters & Mobile Electronics
Beyond A/C, FJC's Power Division produces a focused range of Inverters and related mobile power products — including battery testers, chargers, maintainers, booster cables, and power inverters designed for automotive and light-duty vehicle applications.
