Bosch HVAC 7098575 Sight Glass

The Bosch HVAC 7098575 Sight Glass provides a clear viewing point for observing refrigerant condition and movement through the liquid line. Its transparent section allows liquid flow, bubbles, or moisture indications during operation. Installed in the refrigerant line of HVAC systems, it provides a direct visual reference within the circuit. It remains in the flow path while providing visibility through the line connection. This arrangement makes changes in refrigerant appearance easier to observe during system evaluation and charging checks. The visible flow condition provides useful information when assessing the refrigeration circuit during service.
