A/C Aluminum 4-Valve manifold Gauge Set

Building on the 2-valve design, our Aluminum 4-Valve manifold gauge sets step up to a four-valve configuration with color-coded hoses, allowing simultaneous connection for high pressure, low pressure, vacuuming, and charging lines without constantly swapping hoses — significantly boosting efficiency for complex, multi-task servicing work. Each set includes adapter fittings, an adjustable gauge head, and can tap openers, with refrigerant compatibility spanning R12, R22, R134a, R410, R32, and R1234yf, and select models supporting the full range for maximum versatility.

Like the 2-valve series, these sets are available with moon-cake, square black-yellow, and FT protective sheaths for a durable, ready-to-use build with all necessary accessories included. This series is especially well suited to professional repair shops, large equipment maintenance, and high-intensity work requiring frequent switching between refrigerant systems — an ideal choice for teams that prioritize both efficiency and broad compatibility.
