Description
Product Summary
The NAVAC N2A4B Pro Plus Manifold Gauge is the A2L-ready version of NAVAC's impact-resistant Pro Plus platform. Dual 3-1/8" glow-in-the-dark dials carry R-454B, R-32, R-410A, and R-22 scales, so one manifold handles new A2L installations and the legacy systems still in service.
Class 1.0 accuracy, quarter-turn ball valve handles, and an integrated rubber-covered aluminum body make the N2A4B a durable daily manifold. A hidden folding hook simplifies hanging the gauge at the unit, and a carry case is included. Hoses are sold separately.
