Description
Product Overview
The Yescom AC Manifold Gauge Set (model 39MGH001-MLH60-0123) combines a robust anodized aluminum alloy manifold with precision brass fittings. It includes a blue low‑pressure gauge (-30 to 500 PSI) and a red high‑pressure gauge (-15 to 800 PSI), both featuring a two‑movement, no‑flutter pointer for stable readings. Three 5‑foot charging hoses are color‑coded—red for high pressure, blue for low pressure, and yellow for vacuum or refrigerant bottle—each rated to 800 PSI. Diaphragm valves with swivel seals ensure a positive seal and reduced wear, while rubber gauge covers protect against impact.
Usage
Designed for automotive mechanics, HVAC technicians and serious DIY enthusiasts, this set excels in diagnosing, charging, and recovering refrigerants such as R134A, R410A, R22, and R404A. Whether you are servicing a car air‑conditioning system, a commercial HVAC unit, or conducting leak tests in a workshop, the manifold’s compact dimensions (13.19 × 7.87 × 2.76 in) and 3.75 lb weight make it easy to transport and handle.
