Copeland 998-0669-54 Gasket Set

Repairing 4RH, RK, and RL series compressors requires a seal that handles high-pressure differentials and thermal cycling without failure. The Copeland 998-0669-54 Gasket Set is a comprehensive OEM-standard refrigeration compressor gasket kit designed for commercial HVAC service. This kit includes critical components like the capacity control valve gasket, oil pump o-rings, and specialized suction service valve gaskets, ensuring a gas-tight interface across the entire Copeland compressor rebuild process. Using nitrile rubber and high-grade fluoroelastomers, these gaskets provide superior resistance to common refrigerants and lubricants, preventing the bypass and leaks that lead to system inefficiency. For technicians performing preventative maintenance or a full teardown, this industrial compressor seal kit ensures all mating surfaces—from the terminal plate to the bearing head—meet factory specifications. High-quality replacement HVAC gaskets are essential for maintaining proper compression ratios and reducing vibration-induced noise in demanding industrial environments.

• Direct OEM Compatibility: Specifically engineered for a precise fit on Copeland 4RH, RK, and RL model compressors.
• Multi-Component Kit: Includes oil pump o-rings, terminal plate gaskets, and suction valve seals to support a complete service.
• High-Performance Materials: Utilizing nitrile and fluoroelastomers to withstand extreme temperatures and chemical exposure.
• Leak Prevention: Eliminates refrigerant loss and maintains oil pressure to optimize compressor performance.

Is this gasket set compatible with R-22 and R-404A systems?
Yes, the material composition is designed to be compatible with standard mineral oils and POE lubricants used in these reciprocating compressor applications.

Do I need to purchase the Sentronic oil pump o-ring separately?
No, this set includes the Sentronic oil pump o-ring required for specific Copeland lubrication assemblies.

Can these gaskets be used on 6RH series models?
While primarily listed for 4-cylinder models, many components in the 998-0669-54 kit cross-reference with 6RH series parts. Always verify your specific model number against the technical manual.
