The Grasso Suction Cover is a protective component designed to seal and protect the suction side of refrigeration and HVAC compressors. It prevents contaminants, moisture, and debris from entering the suction port, ensuring that the refrigerant entering the system remains clean. The cover helps maintain the efficiency of the compressor, reduces wear on internal components, and supports smooth operation. By protecting the suction side, it contributes to the overall reliability, performance, and longevity of the equipment.
