HVAC Sight Glass for Copper Lines
This sight glass fits 7/8-inch copper tubing with sweat connections on both ends. It allows technicians to visually inspect refrigerant flow and moisture levels during system service. The plated steel body and copper fittings suit standard HVAC and refrigeration applications.
Installation Uses Standard Sweat Fittings
The 7/8 x 7/8 sweat ends are brazed directly onto copper line sets using conventional torch techniques. The two-piece design includes an O-ring seal that must be seated cleanly to prevent leaks after assembly. Overheating during brazing can damage the O-ring or distort the sight glass window.
Practical Limits of Visual Inspection
The glass window shows liquid refrigerant, bubbles or foam indicating charge condition, but it cannot measure pressure, temperature or exact refrigerant weight. Moisture-indicator elements change colour only within their calibrated range and may not react to all contaminants. The component is restricted from sale in California due to Proposition 65 chemical content.
