PSG Sight Glasses
and Moisture Indicators
Parker’s PSG Sight Glass and Moisture Indicator
provides a quick visual diagnosis of refrigerant and
moisture levels within a system. The sight glass
indicates if the system has the proper refrigerant
level, a restricted dryer, or excessive pressure-drop.
The moisture indicator recognizes moisture within
the system. In conjunction, the sight glass & moisture
indicator provide early warning that a potential failure
exists resulting in corrosion, chemical damage,
restricted flow, or even compressor failure.
Features and Benefits
• Etch-resistant glass with a simple color
comparison provides easy viewing and quick
diagnostics.
• Flare models feature forged brass body and
fittings for corrosion resistance.
• Sweat models feature copper fittings to permit
solder installation without disassembly.
• Leak-proof design is compact and short in
length to easily fit within a unit and provide
accuracy in performance.
• UL listed.
