Product Name：York 464-47821-000 Shaft Seal Assembly
Core Features
1. Advantage：
A compressor that slowly loses refrigerant and oil at the shaft-without a visible leak anywhere else-is almost always a tired shaft seal. The 464-47821-000 is the complete seal package: flange, mechanical seal cartridge, and the three O-rings, all matched to the YORK compressor. Replacing it is a major job, but running a chiller on a weeping seal is worse-it pulls in air, contaminates the oil, and shortens the compressor.

Q: 2 What does a worn shaft seal look like?
A: You will see a thin trail of oil running down the compressor housing near the shaft, or oily dust clinging to that area. The chiller may also need more frequent top-ups of refrigerant that you cannot account for.
Q: 3WDo I have to replace all three O-rings?
A: Yes-they are in the kit for a reason. Reusing old O-rings on a fresh seal guarantees a leak somewhere else on the housing.
