Smart Electric SK163S Liquid Line Drier 3/8 Sweat

Product Description

The SMART ELECTRIC SK163S is a liquid line filter drier designed for use in refrigerant circuits where moisture and contaminant removal is required to protect downstream components. Installed on the liquid line between the condenser and the metering device, this drier absorbs moisture, acids, and particulates that can degrade system performance or cause compressor damage. The SK163S features 3/8-inch sweat connections for copper tubing, making it a straightforward copper-solder installation for HVAC technicians servicing residential or light commercial systems.

This liquid line drier is suited for installation in split-system air conditioners, heat pumps, and refrigeration circuits that use 3/8-inch copper liquid lines. It is a common service replacement installed during system repairs, compressor changeouts, or any time the refrigerant circuit has been opened and exposed to moisture or contaminants. A single unit is sold per order, making it easy to stock individually for service calls.

Key Features

• 3/8-inch sweat (solder) connections compatible with standard copper tubing
• Liquid line placement removes moisture, acid, and debris from the refrigerant stream
• Protects metering devices and compressors from contamination-related damage
• Compact, single-unit form factor suitable for residential and light commercial applications

Compatibility

Designed as an OEM-style replacement liquid line filter drier for HVAC systems and refrigeration circuits using 3/8-inch copper sweat liquid line connections.

Installation Notes

Installation of a liquid line filter drier should be performed by a licensed HVAC technician holding an EPA Section 608 certification for refrigerant handling. Recover all refrigerant from the system before cutting or unsoldering the liquid line. Use a nitrogen purge during brazing to prevent oxidation scale inside the drier and refrigerant circuit. Ensure the drier is installed with the flow arrow oriented in the correct direction of refrigerant flow before recharging the system.
