The Grasso Piston Housing is a critical component in refrigeration and HVAC systems, designed to encase and protect the piston mechanism within compressors. It helps maintain the proper alignment and smooth operation of the piston while shielding it from contaminants, moisture, and debris. The housing ensures optimal performance and efficiency by reducing wear and preventing damage to the piston and other internal components. By providing protection and support, the piston housing contributes to the overall reliability, longevity, and efficiency of the system.
