Supco s219 Copper Strainer 3/8 Inch Inlet

Product Description

The SUPCO s219 is a copper refrigerant strainer designed specifically for reopened HVAC and refrigeration systems. Its oversized screen area captures large quantities of foreign matter — including debris, carbon deposits, and burnout contaminants — before they can damage compressors or other downstream components. With a 3/8 inch inlet and an overall length of 5 inches, this strainer fits into suction or liquid line service in a compact footprint. HVAC technicians and refrigeration service pros install it during system cleanup after compressor burnout or contamination events.

The s219 is intended for use in systems that have been reopened for service, particularly following burnout scenarios where elevated levels of carbon, acid, and particulate contamination are present. The oversized internal screen provides greater filtration capacity than standard-duty strainers, making it well-suited for initial cleanup passes in heavily contaminated systems. It is commonly installed in residential and light commercial refrigeration and air conditioning circuits during compressor replacement or system evacuation and recharge procedures.

Key Features

• Copper construction for compatibility with common refrigerants and refrigeration oils
• Oversized screen area filters large volumes of foreign matter from burnt-out or contaminated systems
• 3/8 inch inlet for standard line connection
• Compact 5 inch overall length for tight installation spaces
• Designed specifically for reopened system service, not just new installations

Compatibility

Designed as an OEM-style replacement and service strainer for residential and light commercial refrigeration and air conditioning systems requiring cleanup filtration after compressor burnout or system contamination.

Installation Notes

Installation is typically performed by a licensed HVAC or refrigeration technician. Recover all refrigerant and depressurize the system fully before cutting into any line or removing any component. Braze or sweat connections using nitrogen purge per standard industry practice to prevent internal oxidation. Replace the strainer after the initial cleanup period if contamination levels were high, as the screen may become restricted during the first service interval.
