Supco s218 Copper Refrigeration Strainer 3/8 Inch Inlet

Product Description

The SUPCO s218 is a copper refrigeration strainer designed specifically for reopened HVAC and refrigeration systems. It filters foreign matter and debris from the refrigerant circuit before it can damage downstream components such as metering devices, compressors, or valve seats. With an oversized screen area, this strainer handles high volumes of contaminants commonly found in systems that have experienced a burnout. Licensed HVAC-R technicians install this component as part of a system cleanup and recommissioning procedure following compressor failure or contamination events.

This strainer is suited for residential and light commercial refrigeration and air conditioning systems where the refrigerant circuit has been opened for service or repair. It is particularly relevant in burnt-out system scenarios where acids, carbon deposits, and metallic particles must be captured before the system is returned to service. The 3/8 inch inlet and .125 CAP outlet make it compatible with common small-diameter refrigerant line configurations found in these applications.

Key Features

• Copper construction for compatibility with refrigerant systems and resistance to corrosion
• Oversized screen area captures large quantities of foreign matter from contaminated systems
• Designed specifically for reopened or post-burnout refrigeration circuits
• 3/8 inch inlet suits common small-bore refrigerant line sizes
• Overall length of 4.5 inches with 0.625 inch OD fits in tight service spaces
• 1 inch feed connection supports standard line configurations

Compatibility

Designed as an OEM-style replacement or service component for residential and light commercial refrigeration and air conditioning systems requiring inline straining on reopened or post-burnout refrigerant circuits.

Installation Notes

Installation should be performed by a licensed HVAC-R technician in accordance with applicable mechanical codes. Recover all refrigerant and depressurize the system completely before cutting into any refrigerant line. The strainer is typically brazed into the liquid line using standard refrigeration-grade brazing alloy with nitrogen purge to prevent internal oxidation. After installation, leak-test all joints and evacuate the system to the required micron level before recharging.
