Mastercool 57272 R22 R404A R410A 2-Way Ball Valve Manifold Gauge Set with 72-Inch Hoses

The Mastercool 57272 is a professional-grade 2-Way Aluminum Refrigerant Manifold Gauge Set designed for HVAC/R technicians servicing systems that use R22, R404A, and R410A refrigerants. Built around a solid extruded aluminum body with an exclusive 3/8" ball valve design, this manifold delivers superior flow compared to standard block designs — making charging, recovery, and evacuation faster and more efficient.

The set ships complete and ready to use, including three 72" x 1/4" SAE color-coded (Blue/Red/Yellow) ball valve hoses with manual shut-off valves, all packaged in a protective plastic carrying case.

Key Features:

• Solid extruded aluminum body for durability and long service life
• Exclusive 3/8" full-bore ball valve design — full 3/8" bore all the way through the block for increased flow over standard block designs
• Quarter-turn ball valve operation — rotates 90° between two Teflon washers, opens and closes quickly with minimal effort even under pressure
• Visual knob position indicator — instantly shows whether valves are open or closed
• 2-1/2" silicone-dampened gauges — smooth needle movement for accurate readings; easily re-calibrated in the field
• Extra-large sight glass for visual refrigerant inspection
• Color-coordinated gauges display R22, R404A, and R410A pressure and temperature correlations
• Extra access port for vacuum line connection
• Large, easy-to-grip knobs for comfortable operation

What's Included:
