Product Overview

The 63mm oil filled refrigerant pressure gauge is designed for HVAC and refrigeration system diagnostics where stable pressure reading is required under compressor vibration and refrigerant cycling conditions.

Refrigeration System Measurement Context

In HVAC systems, pressure behavior varies depending on refrigerant phase changes, compressor load, and ambient temperature. This gauge is designed to support stable monitoring during key operations such as:

• Refrigerant charging and recovery
• System evacuation and vacuum testing
• Compressor discharge and suction pressure monitoring
• Leak detection and service diagnostics

Compatible refrigerants include R134a, R410A, R404A and similar HVAC working media.

FAQ

Why is oil filling used in refrigeration pressure gauges?

It stabilizes the pointer movement by reducing vibration caused by compressor operation and refrigerant pulsation.

What is the advantage of front flange mounting?

It allows direct installation on HVAC panels and service equipment without requiring rear installation space.

Can this gauge be used in outdoor HVAC units?

Yes, stainless steel housing and sealed structure provide protection against humidity and environmental exposure.
