Copeland 020-0028-02 O-Ring Seal

The Copeland 020-0028-02 is a precision-engineered discharge rotalock o-ring seal designed for industrial and commercial compressor service valves. Constructed from high-grade Teflon (PTFE), this gasket provides the critical chemical and thermal resistance required to handle modern refrigerants and high discharge temperatures without deformation. With a 1-1/4 inch diameter and 12-thread specification, it ensures a gas-tight interface between the compressor discharge port and the rotalock fitting, effectively mitigating the risk of refrigerant loss and system inefficiency. This seal is a direct replacement for 020-0028-05 and Daikin McQuay 300000416, making it a versatile component for your truck stock. As a veteran technician knows, using a genuine Copeland 020-0028-02 valve seal is the only way to ensure the long-term reliability of a rotalock valve assembly under high-pressure conditions.

• High-Temperature Resistance: Durable Teflon construction maintains seal integrity in high-heat discharge lines.
• Universal Compatibility: Fits standard 1-1/4" 12-thread service valves commonly found on Copeland and Emerson compressors.
• Leak Prevention: Precision-molded for a gas-tight rotalock connection, preventing atmospheric contamination and refrigerant leaks.
• Chemical Inertness: Resistant to refrigeration oils and all common synthetic and HCFC refrigerants.

• What are the exact dimensions of this seal? This is a 1-1/4" diameter gasket with a 12-thread count, specifically designed for rotalock service valve stems.
• Can this be used on the suction side? While primarily used as a discharge rotalock o-ring seal, it is compatible with any 1-1/4" - 12 rotalock fitting requiring a Teflon gasket.
• Does this replace the 020-0028-05? Yes, the 020-0028-02 is a direct technical replacement for the 020-0028-05 and McQuay 300000416.
