Description
The York S1-400288 is a genuine OEM liquid line filter-drier designed to protect refrigeration and air conditioning systems from the damaging effects of moisture, acid, and particulate contamination. As a direct York replacement part, it ensures precise fit and reliable performance in compatible York equipment.
Product Overview
Liquid line filter-driers are a critical component in any refrigerant circuit. Installed on the liquid line between the condenser and the metering device, this filter-drier performs dual functions — filtering out solid particles and debris while simultaneously adsorbing moisture and acid that can degrade system components, corrode copper tubing, and cause compressor failure.
Key Features & Benefits
- Genuine York OEM replacement part — ensures compatibility and reliable fit
- Dual-function design removes both moisture and particulate contaminants from the liquid line
- Protects the TXV/metering device and compressor from contamination-related damage
- Helps neutralize acid formed during system burnout or refrigerant breakdown
- Maintains system efficiency by keeping the refrigerant circuit clean and dry
- Suitable for use in residential and light commercial York HVAC and refrigeration systems
Applications
- Liquid line installation in York air conditioning and refrigeration systems
- New system installations and system retrofits
- Post-burnout cleanup and system restoration
- Routine maintenance replacement to maintain system integrity
Installation Notes
Always install the filter-drier with the flow arrow pointing in the direction of refrigerant flow toward the metering device. Replace the filter-drier any time the system is opened, after a compressor burnout, or when moisture or contamination is suspected. Follow all applicable local codes and manufacturer guidelines during installation.
