JIFETOR 4 Way AC Manifold Gauge Set - HVAC Diagnostic Tool For Auto & Home AC Systems

For the serious DIYer or HVAC professional, this JIFETOR 4-way AC manifold gauge set is exactly what you need for diagnosing and servicing air conditioning systems! This complete kit features a heavy-duty aluminum manifold with four valves and double movement gauges - blue for low pressure (-30 inHg to 500 PSI) and red for high pressure (-30 inHg to 800 PSI). The set includes four 5-foot color-coded charging hoses made from rubber nylon resin that can handle up to 800 PSI working pressure and 4000 PSI burst pressure. You get adjustable R134A quick couplers that reduce wear on Schrader valves while ensuring airtight connections, plus an adjustable can tap for piercing refrigerant cans and various tank adapters for different connections. The 3-inch large dials are easy to read with no-flutter pointers and built-in calibration screws for measurement accuracy. The middle charging port even has a pressure release valve to purge air from the yellow charging hose. This set works with R404A, R134A, and R410A refrigerants, making it versatile for both automotive and household AC systems. The package comes with a custom blow molding case that keeps everything organized and protected during storage and transport. Important safety note - always wear gloves and goggles when using, and these should only be used by professionals or under professional guidance. The gauges feature sight windows on the manifold to help monitor refrigerant charging better, and the purge valve helps clear air from the system. Whether you're performing evacuations, vacuum checks, diagnostic testing, refrigerant charging, or recovery operations, this comprehensive gauge set provides all the tools you need in one organized package. The quality construction with anti-corrosion materials ensures durability and reliable performance through multiple uses. If you're serious about AC repair and maintenance, this JIFETOR manifold gauge set delivers professional-grade functionality at a much more accessible price point than many commercial options!
