Sight Glass 3/8 x 3/8 Sweat
This Zoro Select sight glass provides a visual window into fluid flow within HVAC and plumbing systems. The sweat connection design requires soldering directly onto 3/8 inch copper piping for a permanent seal. It is built with a plated steel body and copper fittings for corrosion resistance. Technicians use it to verify refrigerant charge or detect moisture in the line.
Verify Pipe Size And Solder Compatibility
Confirm your existing piping measures exactly 3/8 inch outer diameter to match the sweat fitting dimensions. Ensure the system design allows for a soldered joint rather than a threaded or flare connection. Check that the plated steel body and copper fittings are compatible with the specific refrigerant or fluid type in your application. Installation requires appropriate brazing or soldering tools and skill.
Replaces Damaged Or Missing Visual Indicators
This component replaces a cracked, fogged, or absent sight glass that prevents accurate system diagnosis. Upgrading from a unit with corroded fittings restores reliable leak-free performance and clear visibility. The jump is worth it when routine maintenance reveals moisture indication or when a full refrigerant recharge demands verified flow observation. Proposition 65 warning applies.

Questions about this item
What is included with the 3/8 x 3/8 Sweat Sight Glass and what must be purchased separately?
The box contains the sight glass body with copper sweat fittings. Solder, flux and copper pipe are not included and must be sourced separately.
How do I choose the correct version of this sight glass for my line set?
This model is a single 3/8 inch sweat connection size. Select it when your tubing matches that diameter; no other capacities are offered.
What does the Proposition 65 notice mean once the sight glass is installed in a system?
It indicates the product contains a chemical California lists as causing cancer or reproductive harm. Normal sealed installation limits exposure.
