High-Side HVAC Gauge for Refrigerant Systems

This high-side gauge from JB Industries is built for HVAC professionals servicing air-conditioning and refrigeration equipment. It measures pressure on the high side of a manifold set with a 4-inch dial that features glow-in-the-dark markings for readability in low light. The gauge is designed as a direct replacement for manifold gauge sets used with common refrigerants.

Suited for Technicians Using R-134A, R-22.

This gauge suits technicians who need an 800 psi high-side instrument compatible with R-134A, R-22, R-404A and R-410A refrigerants. It is not for low-side measurement, low-pressure testing or systems that require a different connection size or pressure range. Buyers who need a compound gauge or a digital alternative should look elsewhere.

Straightforward Manifold Replacement

Installation consists of threading the 1/8-inch connection onto a compatible manifold block using proper sealant and a wrench on the flats. The gauge accuracy is +/- 1.00 percent of full scale. Over-tightening the connection or exposing the gauge to pressure beyond 800 psi are the most common causes of damage or calibration drift.

Questions about this item

What manifold connection size is required to mount this 1/8 in high side gauge?

The gauge has a 1/8 in connection, so the manifold must accept a 1/8 in fitting to install it directly.

Does the +/- 1.00 percent accuracy cover all refrigerants listed including R-134A, R-22, R-404A and R-410A?

The stated accuracy of +/- 1.00 percent applies across the full 0 to 800 psi range for each of those refrigerants.

How can I verify the glow-in-the-dark red dial is readable after installing the gauge on a charged system?

Pressurise the system within the 0 to 800 psi range, then observe the dial in low light; the glow-in-the-dark red face should remain clearly visible.
