Sight Glass 5/8 x 5/8 Sweat
The Zoro Select sight glass uses a sweat fitting design for copper refrigeration lines. It allows visual inspection of refrigerant flow and moisture indication during system operation. The 5/8 x 5/8 inch connections suit standard residential and light commercial HVAC installations. Installers can verify charge levels without interrupting service.
Check Copper Line Sizing and O-ring Compatibility
Confirm that existing tubing matches the 5/8 inch sweat diameter before ordering. The two-piece body relies on an O-ring seal that must be compatible with the system refrigerant and oil type. Ensure local codes permit sweat connections for the intended application. The 65 warning applies to chemical exposure during handling.
Plated Steel Body with Two-Piece O-ring Design
Plated steel construction resists corrosion in typical mechanical room environments. The two-piece assembly simplifies maintenance by allowing internal access without removing the entire fitting. Copper sweat fittings provide a permanent, leak-resistant joint when brazed correctly. The 5 3/8 inch overall length fits tight piping layouts.

Questions about this item
What fittings come with the Value Brand Sight Glass 5/8 x 5/8 Sweat?
The sight glass includes two copper sweat fittings sized 5/8 inch by 5/8 inch with an O-ring design, giving an overall length of 5 3/8 inches.
How do I decide between sweat and flare versions of this sight glass?
Choose the sweat version when you can braze copper tubing directly into the 5/8 inch fittings; choose a flare version only if your system uses flared tube ends instead.
What does the 5 3/8 inch overall length mean when the glass is installed?
The installed assembly will occupy 5 3/8 inches of straight copper line between the two brazed joints, so allow that space in your piping layout.
