2026 Upgrade 42001 Test and Charging Manifold, for R-22 /R-404A /R-410A | HVAC Manifold Gauge Set with 3-1 /8 inch (80 mm) Color-Coded Gauges, A /C Manifold Gauges, 2-Valve, Manifold Only

Features

• Perfect Compatibility: The 42004 test and charge manifold is equipped with a 3-1/8-inch (80mm) color-coded pressure gauge, specifically designed for measuring R-22, R-404A, and R-410A refrigerants. For maintenance, charging, and recovery of HVAC/R systems
• High-Quality Materials: The 42001 manifold uses a sturdy steel shell to protect the internal mechanism. The gauge mirror uses polycarbonate crystal, providing a clear view and resistance to scratches, achieving a long service life under normal and harsh working conditions, and reducing maintenance interruptions caused by tool wear
• 1% High-Precision Measurement: Equipped with 2 large pressure gauges (red and blue), it achieves a 1% accuracy rating across the entire pressure measurement range. This level of precision is designed to provide a reliable measurement foundation for operations relying on accurate pressure readings and initial system fault diagnosis
• Independent High and Low Pressure Dual Gauges: Real-time synchronous display of system high and low pressure side pressure values and their comparative relationship, with 2 valves and gauges intuitively corresponding. High pressure red gauge: 0 to 800 psi, low pressure blue gauge: -30 to 350 psi
• Precise Readings: The 42001 manifold is equipped with two large color-coded gauges (red/high pressure, blue/low pressure) with a diameter of 3-1/8 inches (80 mm), marked with refrigerant and F scales, significantly enhancing reading clarity and facilitating quick differentiation between high-pressure and low-pressure information
• User-Friendly Design: The manifold features 6 hose connections, with three additional ports on the back for neatly storing connected hoses when the equipment is not in use, helping to keep the work area tidy and protect the hose connections
