This is the removable glass heater cover on our oldest vaporizers built before June 2003. Send us a picture of your vaporizer (views of the front, bottom at least) if you'd like us to specify which model you have.
This 2 inch piece slides onto the metal heating element with a piece of spring steel to help secure it in place.
These older vaporizers used glass bulbs that you can get here.
