A/C Compressor Pressure Relief Valve

An A/C compressor pressure relief valve is incorporated in the manifold and tube assembly to:

• Relieve unusually high refrigerant system discharge pressure buildups, (3103 kPa [450 psi] and above).
• Prevent damage to the A/C compressor and other system components.
• Avoid total refrigerant loss by closing after the excessive pressure has been relieved.
