Aciq Sight Glasses

Overview

The ACIQ DPSG-3S is a combination sight glass and moisture indicator designed for use in air conditioning and refrigeration systems. It gives technicians a fast visual check of refrigerant level and moisture content without opening the system. The etch-resistant glass uses a simple color comparison for quick diagnostics in the field. Copper sweat fittings allow solder installation without disassembling the unit, keeping the job clean and leak-free. The compact, short-body design fits easily inside condensing units where space is limited. The DPSG-3S is suited for residential and light commercial air conditioning systems using 3/8 inch sweat connections on the liquid line. It is typically installed between the condenser and the metering device, where it can flag low refrigerant charge, a restricted filter drier, or excessive pressure drop before those conditions lead to compressor damage. HVAC technicians rely on this type of indicator during commissioning, seasonal startup, and troubleshooting calls.
