Value Ø68 High Pressure Manifold Gauge (R404A/R407C/R22/R134A)

Designed for fast and reliable discharge line pressure measurements in air conditioning and refrigeration (HVAC-R) systems, the Value Ø68 High Pressure Manifold Gauge provides great practicality in the daily operations of technical service teams thanks to its compact design. Fully compatible with standard manifold blocks, this gauge combines high performance and durability.

Wide Refrigerant Compatibility and Clear Reading (R404A/R407C/R22/R134A)

Compatible with R404A, R407C, R22 and R134A, the refrigerants most commonly used in industrial and commercial refrigeration systems, this pressure gauge offers our technicians error-free reading with its inner scale color-coded for each refrigerant. The outer red color coding representing high pressure (discharge) lines creates a visual standard and makes safe work in the field easier.

Practical Usage Note for Field Technicians

Technician's Note: This compact 68 mm pressure gauge is ideal for technicians looking for a gauge that does not take up much space in the tool bag, especially when working in tight spaces. When checking discharge line pressure on industrial refrigerators using R404A or on systems being charged with R134A, thanks to the stable needle mechanism you can obtain clear readings without feeling the vibrations at compressor start-up. When tightening the brass connection threads into the manifold block, paying attention to the use of PTFE tape or checking the O-ring is sufficient for leak-tightness.
