OEMTOOLS M84661-AZ Manifold Gauge 134A

Manifold gauge sets, also known as HVAC gauges or refrigeration gauges, are essential to diagnose and repair refrigerators or cooling systems, since they measure both low and high refrigerant pressure. This gauge set features a heavy duty forged brass body. The large all metal handles are angled for ease of operation and the free floating piston type valves reduce O-ring wear. The silicone dampened gauges smooth out needle movement and the gauges can be recalibrated in the field to maintain accuracy.
