Carrier CSG-163-S Liquid Line Filter-Drier with Integrated Sight Glass 3/8" ODF

The Carrier CSG-163-S is a liquid line combo filter-drier with an integrated moisture-indicating sight glass, part of the Sporlan Catch-All® CSG Series. Designed for HVAC&R systems, this unit combines a high-performance Catch-All® filter-drier with a See-All® sight glass into a single factory-tested, leak-free assembly — eliminating two field-braze joints compared to installing the components separately.

The Catch-All® desiccant core effectively captures and retains moisture, acid, scale, solder particles, carbon, sludge, and other solid debris, protecting compressors and thermal expansion valves with negligible pressure drop. The integrated sight glass allows for quick visual inspection of refrigerant flow and system moisture levels without additional fittings.
