What makers wrote about this bin

  • I'm a retired HVAC technician and I needed to replace my systems filter dryer and added this sight glass after filter dryer at my indoor unit , so I could make sure the indoor coil is getting liquid refrigerant and alert me of moisture in the system, that will slowly destroy an ac system

  • Make sure to remove the lens cap and gasket before you sweat the fitting in. Hi heat will distort the gasket and make it leak.
