Black Max Mechanical Manifold Gauge Set 2 Valve

SKU CH-0R3Z-V4ZB0

Two-valve mechanical manifold gauge set for multiple refrigerants with three 60-inch black-chrome hoses and ball valves, measuring 30 in Hg to 500 psi low side and 0 to 800 psi high side within

  • Aluminum body resists corrosion for lasting durability
  • Two valves control refrigerant flow precisely
  • Three 60 in black chrome hoses reach distant service ports
  • 0 to 800 psi and 30 in Hg to 500 psi ranges cover multiple refrigerants
  • +/- 1.00 percent accuracy ensures reliable pressure readings

Mechanical Manifold Gauge Set

The Black Max MBH4P5EZ is a two-valve mechanical manifold gauge set built for HVAC and refrigeration technicians who service multiple refrigerants. It ships with three 60-inch hoses and carries UL/SAE markings for field use. The aluminum body and black-chrome hoses are intended for daily service work.

Pressure range and accuracy

The gauges read 0 to 800 psi on the high side and 30 in Hg to 500 psi on the low side with a stated accuracy of +/- 1.00 percent. This range covers common residential and light-commercial refrigerants. Technicians needing higher-pressure readings for transcritical CO2 or other specialty gases should verify suitability before purchase.

Connection and hose handling

Each hose terminates in a 1/4-inch fitting with integrated ball valves for quick refrigerant isolation. The 60-inch length gives reach around condensing units, though tight service panels may require careful routing. New users sometimes forget to open the ball valves before reading pressures, which yields false zero readings.

Questions about this item

What does the 800 psi high-side reading mean when I'm charging a system?

The gauge's 0 to 800 psi scale covers the high-pressure side of common refrigerants, so you can read condenser pressure directly while charging or diagnosing.

How do the 1/4 inch connections and UL/SAE listing affect hose compatibility?

The 1/4 inch flare fittings match standard HVAC hoses, and the UL/SAE rating confirms the assemblies meet industry pressure-safety standards for refrigerant use.

Will the 60 inch hoses and aluminum block reach my service ports without extra extensions?

The 60 inch black-chrome hoses give you roughly five feet of reach from the manifold block, which is sufficient for most residential and light-commercial service ports.
