HVAC manifold gauge set

The JB Industries M2-25515 manifold gauge set is built for HVAC technicians who service R-404A, R-407A and R-407C systems. It includes two valves and color-coded refrigerant dials for quick pressure identification. A free-floating dual O-ring sealing system speeds evacuation and charging tasks. All-metal gauges and replaceable fittings support daily field use.

Pressure range and accuracy

The gauges read from 30 in Hg vacuum up to 800 psi on the high side and 500 psi on the low side. Accuracy is rated at +/-3-2-3 percent across the scale. Brass construction and 1/4 in flare fittings handle normal service pressures without leaks. Plastic hand wheels turn easily even when wearing gloves.

Sustained job-site durability

The pull-out proof hanging hook keeps the set secure on a ladder or service cart during long jobs. Replaceable intake and hose fittings allow quick repair without replacing the whole manifold. All-metal gauge cases resist impact better than plastic alternatives. The 5 ft length gives enough reach for typical residential and light commercial equipment.

Questions about this item

How do I install the JB Industries M2-25515 manifold gauge set and what step is commonly missed?

Connect the 5 ft hoses to the 1/4 in brass fittings on the system service ports; the step often missed is tightening the free-floating dual O-ring seals by hand before using the plastic hand wheels to prevent refrigerant leaks.

What maintenance or replacement will the JB Industries M2-25515 manifold gauge set need over time?

The replaceable intake and hose fittings are designed for easy repair; O-rings in the dual sealing system should be inspected and swapped when they show wear to maintain the +/-3-2-3 percent accuracy across the 0 to 800 psi and 30 in Hg to 500 psi ranges.

What is the first limit reached on the JB Industries M2-25515 manifold gauge set during sustained high-pressure use?

The high-side gauge tops out at 800 psi and the low-side gauge at 500 psi; exceeding either limit risks damaging the all-metal gauge internals before any other component fails.
