Carrier 19C35-6151-C3 Sight Glass

Carrier 19C35-6151-C3 Sight Glass is a replacement glass component for Carrier refrigeration equipment, providing a clear viewing window into the liquid line so technicians can monitor the state of the refrigerant as it flows through the circuit during service or charging tasks. The part is cataloged as a “Sight Glass” or “Glass Liquid Sight” with NSN 6680-00-868-2838, and it is commonly accompanied by a compatible gasket (19DK119-1103) to ensure a proper seal during installation. As a Carrier-branded component, the 19C35-6151-C3 identifies a specific glass unit within Carrier’s parts catalog, and distributor and carrier-service listings confirm its function as a viewing device for the refrigerant liquid column. This sight glass is used in applications involving Carrier equipment where visibility of the liquid line is required, including marine and industrial refrigeration contexts, as evidenced by carrier-related marine parts listings that identify 19C35-6151 as a sight glass option and note associated gasket parts. Replacing a damaged or worn sight glass with the 19C35-6151-C3 preserves the ability to observe liquid flow through the glass, aiding diagnostic checks and ensuring technicians can verify liquid presence and line conditions during maintenance.
