2-Valve Manifold for R-12 R-22 R-502

The JB Industries 24078 is a 2-valve manifold gauge set built for automotive and HVAC technicians servicing R-12, R-22 and R-502 systems. Its aluminium body houses a floating O-ring sealing system designed to resist flutter and surge during operation. The kit includes three 6 ft hoses and a sight glass for visual refrigerant checks.

Technicians needing basic 2-valve service

This suit technicians who need a straightforward 2-valve manifold for the listed refrigerants and pressure ranges. It does not suit buyers who require four-valve manifolds, digital readouts, or compatibility with refrigerants beyond R-12, R-22 and R-502.

Pressure range 0 to 500 psi and 30 in Hg to 350 psi

The gauges read 0 to 500 psi on the high side and 30 in Hg to 350 psi on the low side with a stated accuracy of +/-3-2-3 percent. This range decides whether the set matches the system pressures you work with.

Questions about this item

What pressure range does the 2-valve manifold gauge cover for R-12, R-22 and R-502 refrigerants?

The gauge reads 0 to 500 psi on the high side and 30 in Hg to 350 psi on the low side with a +/-3-2-3 percent accuracy class.

What hose length and fitting size are required to connect this manifold set?

Three 6 ft hoses with 1/4 in fittings are included, so the unit mounts directly to standard service ports without extra adapters.

How are the valves sealed, and what common mistake causes leaks during installation?

Valves use a floating O-ring sealing system; the frequent error is over-tightening the hose couplers, which crushes the O-ring and prevents it from floating to seal properly.
