Cooling Sight Glasses

5 results found that include 27 products

A sight glass from Grainger has plated steel and copper fittings for a secure, corrosion-resistant fit, and is UL listed for 650 psig. But if you're repairing or rebuilding an air conditioner, refrigerator, or condensing unit, Grainger offers you more. Replace your corroded valve with a new thermostatic expansion valve from Parker. Choose a manifold gauge set that has precision flutter- and pulsation-resistant gauges with protective boots. And replace your old temperature control with a new, more reliable one. Stay cool with sight glass and moisture indicator choices from Grainger.Close
