QUICK TIPS Can I order just the sight glass?
Yes - the VL-3A sight glass is a cost effective, 3-A Certified, high operating temperature and pressure sight glass that can be used for any sanitary process sight glass needs.
Can I use this as a combination sight glass and light? The 4.0" TC model's light is offset from center, and has enough visibile sight glass space for using as a combination sight glass and light. Smaller sizes are intended for process lighting only and a secondary source for viewing (e.g., manway,
additional sight glass) is required. Is this unit 3-A Certified?
The VL-3A model sight glass used in the VessaLite™ assembly is 3-A Certified, which is the only process contact part of the assembly.
Can I use the light with another or existing sight glass? Yes - if using with an existing sight glass, the dimensions of the sight glass opening, process connection, and height of sight glass will need to be supplied to make sure the light tri-clamp bracket will work.
