Parker 620 Liquid Line Dryer

The Parker 620 is a liquid line filter dryer designed for HVAC and refrigeration systems. It suits technicians who need a reliable component to remove moisture and contaminants from the refrigerant circuit. The unit features a copper body with solder connections and a built-in charging valve for service access. It is intended for professional installation in compatible piping configurations.

Refrigerant capacity limits

This dryer is rated for a capacity of 2 ton when used with R-22 and R-410A refrigerants. It supports all CFC, HCFC, and HFC refrigerant types within that capacity range. The connection size accommodates 1/4 to 5/16 inch tubing with an overall length of 9 1/2 inches. Systems exceeding the rated tonnage require a larger dryer to maintain proper flow and filtration.

Replaces clogged or saturated dryers

The Parker 620 replaces an existing liquid line dryer that has become restricted or saturated with moisture. The upgrade is worth it when system diagnostics indicate high pressure drop, acid formation, or reduced cooling performance due to a spent desiccant core. It restores proper refrigerant flow and protects system components from corrosion and freeze-up. Installation requires recovery, soldering, evacuation, and recharge procedures.

Questions about this item

Should I pick the R-22 or R-410A version for my system?

This single dryer handles both refrigerants, each rated at 2 ton capacity, so no separate version is needed.

What does the 2 ton rating mean when the dryer is installed?

It indicates the maximum cooling capacity the filter-dryer can support for either R-22 or R-410A systems.

What does the 1/4 - 5/16 inch solder connection limit in practice?

It fits copper tubing in that size range and requires soldering, fixing the line size you can connect.
