Product Summary
The NAVAC N4A4B Pro Plus 4-Valve Manifold Gauge brings four-valve workflow efficiency to A2L refrigerant service. Independent quarter-turn ball valves for the low side, high side, refrigerant, and a dedicated 3/8" vacuum port let technicians evacuate, charge, and recover from a single hookup.
The Class 1.0 accurate 3-1/8" glow-in-the-dark dials display R-454B, R-32, R-410A, and R-22 scales, covering the new A2L systems alongside the legacy equipment still in the field. An impact-resistant aluminum body with a rubber cover stands up to daily jobsite use. Gauge and carry case only; hoses are sold separately.
