Supco HP163S Bi-Flow Heat Pump Filter Drier 16 Cu In 3/8" ODF

The Supco HP163S is a bi-directional liquid line filter drier engineered specifically for heat pump applications. With a 16 cubic inch capacity and a 3/8" ODF (Outside Diameter Flare) sweat connection, it effectively removes moisture, acid, and contaminants from refrigerant circuits in both heating and cooling modes — making it the ideal replacement or new-installation drier for heat pump systems using CFC, HCFC, and HFC refrigerants.

Key Features:

• Bi-directional (bi-flow) design — internal check valves allow refrigerant flow and filtration in either direction
• 16 cubic inch desiccant core housed in a compact 2½" diameter shell
• High moisture and acid removal — desiccant blend of 75% molecular sieve and 25% activated alumina
• 40-micron filtration to protect system components from particulate contamination
• Maximum working pressure: 600 PSIG
• Compatible with all refrigerants, including R290 (propane)
• Copeland® approved for POE oils
• Corrosion-resistant epoxy powder paint finish for long-term durability
• Connection: 3/8" ODF (solder/sweat)
