Value Ø68 Low Pressure Manifold Gauge (R410A/R407C/R22/R134A)

Designed for suction line pressure checks and precise vacuum work in air conditioning and refrigeration (HVAC-R) systems, the Value Ø68 Low Pressure Manifold Gauge, with its compact size and industrial durability, is one of the indispensable measuring instruments for our technicians in the field. Fitting directly onto standard manifold blocks, it speeds up troubleshooting and refrigerant charging.

Multi-Refrigerant Compatibility and Retard Protection

Fully compatible with R410A, R407C, R22 and R134A, the refrigerants most frequently encountered in the industry, this gauge saves technicians the trouble of carrying multiple gauges thanks to the special color-coded scale on its inner dial. With blue color coding representing the low-pressure line, it upholds occupational safety standards. In addition, the RETARD zone at the end of the dial protects the internal mechanism of the gauge against sudden pressure rises (for example, the static pressure that equalizes when the unit is switched off), preventing failure.

Class 1.6 Accuracy and Technical Specifications

With its Class 1.6 accuracy class offering the lowest margin of error in system leak tests and charging, the key technical details of the instrument are as follows:

• Brand: Value
• Product Type: Low Pressure (Suction Line) Manifold Gauge
• Compatible Refrigerants: R410A, R407C, R22, R134A (4 different refrigerant scales on a single dial)
• Dial Diameter: Ø68 mm (Compact design for practical use in tight spaces)
• Pressure and Vacuum Range: -30 inHg ~ 550 psi / -1 ~ 38 bar (Including retard protection zone)
• Accuracy Class: Class 1.6 (Full compliance with industrial measurement standards)
• Connection Type: Corrosion-resistant, leak-tight standard brass bottom connector.

Practical Usage Note for Technicians in the Field

Technician's Note: R410A, widely used especially in inverter air conditioners, reaches high static pressures when the system is stopped. When standard low pressure gauges are exposed to this pressure, the needle calibration may be disturbed. However, thanks to the RETARD zone extending up to 550 psi on the Value Ø68, you do not need to remove the gauge from the line when the unit is switched off, and the mechanism is not damaged. Thanks to its 68mm diameter, it takes up minimal space in your toolbox.
