R134A Low and High Pressure Quick Coupling Set NORDBERG NFA7L

The NORDBERG NFA3H is designed for coupling to the low and high pressure port of a car air conditioner without opening access to the refrigerant circulation system.

Type of refrigerant: R134a.

Functional

• Turning the shut-off valve clockwise activates the mechanism of lowering the depressor rod, which presses the spool and thus opens access to the refrigerant circulation system.
• The valve avoids mechanical failure due to physical resistance to the internal pressure of the system. Without the valve, trying to connect the port, it is possible to break the tube on which the port is located.
