Cooling Sight Glasses

SupplyApp's sight glass is UL approved for 650 psig and contains plated steel and copper fittings for a secure, corrosion-resistant fit. If you're repairing or replacing an air conditioner, refrigerator, or condensing unit, though, SupplyApp has more options. Replace your rusted thermostatic expansion valve with a new Parker thermostatic expansion valve. Choose a manifold gauge set with protective boots and precision flutter- and pulsation-resistant gauges. Also, replace your old thermostat with a new, more dependable one. SupplyApp offers a variety of sight glass and moisture indicator options to help you stay cool.
