The M2-36 manifold gauge is a professional-grade diagnostic and service tool set primarily designed for HVAC technicians working with R12, R22, and R502 refrigerants. This industry-standard set is used for testing, evacuating, and charging air conditioning and refrigeration systems.
Technical Specifications
According to JB Industries and Century Tool, the M2-36 features a specific set of standard components:
- Body Material: A heavy-duty, forged brass manifold bar designed for durability.
- Gauges: Two 2.5-inch (63.5mm) all-metal gauges with color-coded dials for easy refrigerant identification.
- Hose Set: Includes a set of three 36-inch (91 cm) CCL hoses (typically Red, Blue, and Yellow) with 1/4" SAE fittings.
- Valves: A two-valve system utilizing a free-floating dual O-ring sealing system, which reduces wear and allows for faster evacuation and charging.
- Pressure Rating: Standard hoses for this type of kit often feature a 500 PSI max working pressure and a 2500 PSI burst pressure.
Key Design Features
- Dampened Gauges: The gauges are surge or silicone-dampened to reduce needle movement, ensuring more accurate and steady readings.
- Improved Clearance: The manifold bar is angled to provide better knuckle clearance when rotating the handwheels.
- Field Recalibration: Gauges can be easily recalibrated on-site to maintain accuracy over time.
- Storage & Handling: Equipped with a heavy-duty hanging hook and replaceable intake/hose holder fittings for convenient hose storage.
