GM Performance 2724982 A/C Compressor Pressure Relief Valve

The GM Performance 2724982 is a genuine OEM A/C Compressor Pressure Relief Valve engineered to protect your vehicle's air conditioning system from dangerous overpressure conditions. This safety-critical component is a direct factory replacement, built to the same exacting standards as the original part installed at the assembly line.

When refrigerant pressure inside the A/C compressor exceeds safe operating limits — due to system blockages, overcharging, or extreme heat — this pressure relief valve opens to release excess pressure and prevent damage to the compressor and surrounding HVAC components. Replacing a faulty or leaking relief valve restores proper system protection and helps ensure reliable A/C performance.

Key Features:

• OEM Genuine Part — designed, engineered, and tested to GM's rigorous quality standards
• Direct Fit — engineered as an exact replacement for the factory-installed valve; no modifications required
• Overpressure Protection — relieves excess refrigerant pressure to protect the compressor and A/C system components
• Factory Quality — held to federal safety and quality standards and backed by the GM Replacement Parts Limited Warranty
• Included with Compressor Assembly — also sold individually as a standalone service replacement part

This part is also referenced as a GM HVAC Pressure Switch or GM A/C System Valve. It is compatible with a broad range of 1984–2009 GM vehicles across the Buick, Cadillac, Chevrolet, and GMC model lines. For guaranteed fitment, always verify against your vehicle's VIN before ordering.
