Copeland 528-1378-00 Assembly

The Copeland 528-1378-00 Oil Tube Assembly is a precision-engineered OEM compressor part designed to facilitate reliable oil transport within high-demand refrigeration and air conditioning systems. This heavy-duty 1/2-inch oil tube serves as a critical conduit for pressure-fed lubrication, ensuring that 50/60 Hz Copeland compressors maintain the specific oil levels required to protect internal reciprocating or scroll components from friction and thermal wear. Manufactured from high-grade metal alloys, this assembly is built to withstand the rigorous vibration and thermal cycling common in commercial HVACR environments.

For technicians performing a compressor oil pump service or overhaul, replacing the Copeland assembly 528-1378-00 is an essential step to prevent oil starvation and maintain the hydraulic integrity of the lubrication circuit. This component is specifically matched to Emerson Copeland specifications for a drop-in fit, eliminating the need for field modifications while ensuring the efficient distribution of polyolester (POE) or mineral oils. Using genuine refrigeration compressor parts like this assembly helps optimize system longevity and reduces the frequency of emergency maintenance interventions.

• Ensures consistent oil circulation to prevent internal compressor overheating.
• Constructed from durable metal alloy to resist fatigue and vibration stress.
• Standard 1/2-inch diameter provides unrestricted flow for optimal lubrication performance.
• Critical for maintaining high-efficiency operation in commercial refrigeration systems.
• Direct OEM replacement ensures precise alignment with the crankshaft oil pump.

• Is this assembly compatible with specific Copeland Discus models? Yes, this assembly is designed for use across several Copeland semi-hermetic series; verify your model and serial number to ensure an exact match.
• Does this tube-oil assembly include the mounting gasket? Note that gaskets are typically sold separately or as part of a complete oil pump kit; this part number covers the tube assembly itself.
• What causes these oil tubes to fail? Stress from excessive vibration or oil acidification can degrade the assembly over time, making it a critical inspection point during major teardowns.
