Description

49974 4-Valve Test and Charging Manifold designed specifically for high- pressure, new environmentally friendly refrigerant systems R-32, R-454B, and R-410A, ensuring accurate and reliable readings.The four-valve design allows simultaneous connection to the high and low pressure sides, refrigerant tank, recovery unit, or vacuum pump. Throughout the entire diagnostic, recovery, vacuuming, and charging process, there is absolutely no need to disassemble or switch any hoses, greatly improving work efficiency and eliminating the risk of refrigerant leaks caused by frequent switching.By flexibly controlling the four valves, you can easily isolate the instrumentation section from the system, or isolate the high-pressure side and low-pressure side separately. This makes accurately locating system leaks and testing individual compressor functions simpler and more accurate than ever before, making it an invaluable tool for troubleshooting complex commercial systems.Reduced downtime, labor cost savings, and eliminated refrigerant waste will quickly make this meter set one of the most cost-effective pieces of equipment in your toolbox.

  • Hvac guys should know how to use analog gauges before buying digital.
My go to gauge, can’t trust a helper to make sure valves are open before opening nitrogen bottles, tired of replacing so it’s hands off for him.

  • High Quality 4-Valve Manifold - Perfect for New A2L Refrigerants
This Zhenx 49974 4-valve manifold is an excellent, professional-grade tool that I will definitely be carrying on my daily HVAC jobs. Right out of the box, the build quality stands out. The main gauge body is made of high-quality aluminum that feels rugged and durable. The four valves are wrapped in a nice rubber coating, offering a great grip, and they operate incredibly smoothly when opening and closing.The 3-1/8" gauges themselves are housed in a sturdy metal case, ensuring they can handle the rough environment of field work. A really smart design feature is the removable plug on the front of the gauges, which makes it incredibly easy to zero them out whenever necessary.What I love most about this manifold is the extra ports. Having a 4-valve setup allows you to easily hook up a recovery tank, vacuum pump, or micron gauge at the same time without having to constantly swap hoses in and out. It saves a lot of time on the job site and keeps the system sealed. It is perfectly calibrated for R-32, R-454B, and R-410A, making it a future-proof addition to my tool setup as the industry transitions to A2L refrigerants. Note that this is the manifold only and does not come with hoses, so you will need your own. Overall, it is a high-quality, reliable tool that I highly recommend. ... show more
