Four Seasons 1321N A/C Compressor Replacement Kit

The Four Seasons 1321N is an A/C Replacement Kit designed to provide all the essential components needed for a complete and successful automotive air conditioning compressor replacement. Four Seasons' A/C replacement kits are engineered to work together as a system, helping restore proper cooling performance and protect the new compressor from premature failure caused by contamination or moisture.

Why Replace the Full Kit?

When an A/C compressor fails, debris and contaminants circulate throughout the entire system. Replacing only the compressor without servicing supporting components risks immediate re-contamination, leading to repeat failures. This kit addresses that risk by bundling all the critical supporting parts in one convenient package.

Kit Contents May Include:

• Accumulator or receiver/drier — removes moisture and contaminants to protect system integrity
• Orifice tube or expansion valve — meters and regulates refrigerant flow through the system
• Compressor oil — ensures proper lubrication of the new compressor from the first startup
• O-rings and gaskets — provides leak-free sealing at all connections

Key Features:

• All components assembled and shipped together for convenience
• Engineered to meet or exceed OEM specifications
• Helps satisfy compressor warranty requirements by replacing all recommended components simultaneously
• Compatible with R-134a refrigerant systems (verify fitment for your specific application)
• Backed by Four Seasons' trusted quality in thermal management and HVAC parts
