High-Side HVAC Gauge

The Dayton 4PDK5 is a high-side pressure gauge designed for HVAC manifold sets. Its red dial face provides clear identification during refrigerant charging and diagnostics. The gauge suits technicians servicing residential or light commercial air-conditioning and refrigeration systems.

Refrigerant Compatibility

The gauge scale covers R-22, R-404A, R-407C and R-410A, so one instrument handles the most common refrigerant types encountered in the field. This reduces the need to swap gauges when moving between jobs that use different refrigerants.

Connection and Pressure Check

Verify that your manifold set accepts a 1/8-inch connection before fitting this gauge. Confirm the system’s normal operating pressure stays within the 0 to 800 psi working range to avoid over-pressure damage.

Questions about this item

Will the 800 psi high-side gauge need recalibration or replacement after extended refrigerant charging cycles?

The gauge is a mechanical replacement part for manifold sets; it has no user-serviceable calibration and is replaced if the needle drifts or the Bourdon tube fatigues.

What is the maximum working pressure the red high-side gauge can sustain continuously during a long charging session?

The gauge is rated for a working pressure range of 0 to 800 psi, which is its upper limit under sustained use.

Does the 1/8 in connection or the gauge housing generate noticeable heat when the system runs at high-side pressure all day?

The gauge body is a passive pressure indicator with no powered components, so it does not produce heat; only the refrigerant line temperature transfers to the housing.
