The Gram Seal Cover, Shaft is a protective component used in Gram compressors to enclose the shaft seal. The shaft seal prevents refrigerant leakage around the rotating shaft, ensuring the compressor operates efficiently and without loss of refrigerant. The seal cover helps protect the seal from contaminants and damage, maintaining its integrity and functionality. By safeguarding the seal, the cover contributes to the overall performance, reliability, and longevity of the compressor in refrigeration and HVAC systems.
