Supco SG114 Allin Liquid Eye Refrigerant Sight Glass 1/4" Flare

The Supco SG114 is an Allin Liquid Eye refrigerant sight glass designed for HVAC and refrigeration systems. This professional-grade component allows technicians to visually monitor refrigerant flow and determine the state of charge in cooling systems.

Key Features:

• Unique "see-thru" feature with magnified dot for quick, easy refrigerant level indication
• 1/4" male flare x 1/4" female flare connections for easy installation
• Solid brass body construction for durability and corrosion resistance
• Shock-resistant glass withstands field conditions and vibration
• 3/4" hex size for wrench installation
• 3.06" overall length fits tight spaces
• Color bar designed for HFC refrigerants
• Replaces A-1 F5904 sight glass

Sight glasses provide critical visual indication of bubbles in the refrigerant stream that could adversely affect system performance. For optimum cooling system performance, a solid column of refrigerant should be present at the expansion valve. The SG114 should be installed in the liquid line as close to the expansion valve as possible for best results.
