Description
The Sporlan Controls 409999 Drier with Sight Glass CSG-304-S is a filter-drier assembly used in circuits to remove moisture and contaminants while allowing visual monitoring of refrigerant condition. It features 1/2″ ODF connections and integrates a desiccant core that absorbs moisture and captures debris as refrigerant passes through the body. The built-in sight glass provides a clear indication of flow condition and system status. Within HVAC systems such as refrigeration lines, air conditioning units, and heat pump installations, it is brazed into the liquid line to protect expansion and compressors, supporting stable flow and consistent system operation.
