Description
Overview
The Supco SG114 is an all-in-one liquid line sight glass designed for refrigeration and air conditioning systems. This compact, reliable component allows HVAC/R technicians to visually inspect refrigerant flow conditions and detect moisture contamination directly in the liquid line — all in a single, integrated unit. By combining a clear sight glass with a built-in moisture indicator, the SG114 eliminates the need for separate components and simplifies system diagnostics.
