JB Industries M2-870 Low Side Gauge Blue 350 psi
Low-side HVAC gauge reads 30 in Hg to 350 psi with 1.00 percent accuracy for R-12, R-22 and R-502 systems
- ColorBlue
- Low-side readings for R-12, R-22, R-502 systems
- +/- 1.00 percent accuracy ensures precise diagnostics
- 30 in Hg to 350 psi range covers vacuum and pressure
- Blue dial colour identifies low-side at a glance
- 3-1/8 in diameter fits standard manifold gauge sets
Replacement Low-Side Gauge for Manifold Sets
This JB Industries M2-870 gauge replaces a low-side component on existing manifold assemblies. It is built for technicians who service refrigeration and air-conditioning systems using R-12, R-22 or R-502 refrigerants. The blue dial face provides clear pressure identification during charging and recovery work.
Suits Single-Gauge Replacement Needs
Technicians who only need to swap a damaged low-side gauge will find this unit matches the required function. Shops requiring a complete new manifold set or a high-side gauge should look at a different product because this listing covers the low-side instrument alone.
Accuracy Is +/- 1.00 Percent
The gauge reads from 30 in Hg vacuum up to 350 psi with a stated accuracy of +/- 1.00 Percent. This tolerance determines whether the instrument meets the precision demands of your diagnostic procedures.

Questions about this item
Which manifold gauge set uses a 1/8 in connection so this low side gauge fits?
Any manifold set with a 1/8 in port accepts the gauge; the blue colour marks it for low side service.
Can this gauge stay on a set that still carries R-12 or R-502 refrigerant?
Yes, the dial is rated for R-12, R-22 and R-502 so it works with older refrigerants.
How do I confirm the +/- 1.00 percent accuracy after installation?
Compare the needle reading at 30 in Hg vacuum and at 350 psi against a calibrated reference gauge.
