Techsun High Pressure Gauge Ø70 mm (Silicone Protected) | 1/8" NPT | R134a / R404A / R410A / R32

The Techsun High Pressure Gauge (Ø70 mm) is a pressure gauge with refrigerant temperature scales used to measure the high pressure (discharge) side in split air conditioners, VRF and commercial refrigeration systems. It is connected on a manifold set or individually, and has scales for reading the condensing temperature directly for R134a, R404A, R410A and R32 refrigerants. It is protected against impact and vibration by a silicone (rubber) protective boot.

High Pressure Gauge for Refrigeration and Air Conditioning (Ø70)

The dial has a dual bar and psi scale with R-134a / R-404A / R-410A / R-32 refrigerant temperature curves; while reading the pressure, the technician also sees the corresponding condensing temperature directly. It has a 1/8" NPT bottom connection.

Technician Tips

• Connect to the high pressure side: This gauge is for the discharge (high pressure) line; use the low pressure gauge for low pressure measurement.
• Read the condensing temperature corresponding to the pressure you read on the scale of the refrigerant you are measuring (R410A/R32/R404A/R134a).
• The silicone boot provides protection in the field; still, do not drop the gauge and avoid excessive pressure surges (hydraulic shock).
• For sealing, use a suitable gasket/PTFE tape on the 1/8" NPT connection; do not overtighten.
