The Shrinkfast 998 Heat Gun Left Hand Housing (Part# 16 on the diagram) is a molded plastic housing that works with the Right Hand Housing (part #16) to hold almost all parts of the heat gun inside. It is designed to allow a specific amount of air to be drawn into the Body (part #10) to create a mixture of fuel and oxygen optimal for combustion. This Housing should be replaced if there are any holes, cracks, or missing pieces to allow for optimal flame distribution and to prevent any safety hazards.
