Upgrade 42201 Test & Charging Manifold with 3-1/8" (80 mm) Gauges Set

The DRAKO-MYXX 42201 Test and Charging Manifold Set is designed for technicians servicing HVAC/R equipment. Built specifically for system maintenance, charging, and refrigerant recovery, this diagnostic tool provides pressure readings for R-22, R-404A, and R-410A systems. It comes fully equipped with the central manifold and three 60-inch color-coded hoses, making it ready for field service right out of the box.

Visibility and durability are the core strengths of the gauge design. The 3-1/8-inch (80 mm) dials utilize color coding and an anti-vibration mechanism to display high- and low-side pressures steadily. To handle tough work environments, the internal components are housed in a sturdy steel shell and protected behind scratch-resistant polycarbonate crystal, ensuring the dials remain readable over repeated use.

Performance specifications support heavy-duty system servicing. The manifold handles a working pressure of 800 psi (55 bar) and a burst pressure rating of 4000 psi (275 bar), functioning in ambient temperatures between -20°F and 180°F. The included yellow, red, and blue 1/4-inch hoses feature compact ball valves and leak-free connections to help speed up refrigerant recovery while minimizing connection steps.

Keep in mind that the unit is specifically configured for three refrigerant types: R-22, R-404A, and R-410A. Technicians working with other blends will need alternative gauges. Additionally, because the tool operates under high pressures, users must observe standard safety practices, including wearing protective gloves and safety glasses during operation.

Verdict: The DRAKO-MYXX 42201 Manifold Set is a solid, straightforward choice for HVAC technicians and mechanics who frequently maintain R-22, R-404A, and R-410A systems. Its steel housing, large anti-vibration dials, and integrated ball-valve hoses offer dependable everyday performance for charging and recovery tasks.

• Gauge Diameter: 3-1/8 inches (80 mm)
• Compatible Refrigerants: R-22, R-404A, R-410A
• Hose Length: 60 inches
• Hose Fitting Size: 1/4 inch
• Working Pressure: 800 psi (55 bar)
• Burst Pressure: 4000 psi (275 bar)
• Operating Temperature: -20°F to 180°F (-28.8°C to 82.2°C)
• Housing Material: Steel shell with polycarbonate crystal lens

A great fit if you:

• Service air conditioning and refrigeration units running on R-22, R-404A, or R-410A.
• Want high-visibility 80 mm dials with anti-vibration protection for steady pressure readings.
