It is used in industrial and vehicle fluid systems—such as fuel, hydraulic, or air lines—to quickly check for flow, clarity, or contamination. In a heavy-duty truck setting, a sight glass might be installed in a fuel supply or filtration circuit for at-a-glance diagnostics. The specific part number SG3E does not appear in any manufacturer catalog searched, but the 3-inch inline designation and the price point suggest a robust, possibly stainless-steel or extra-durable sight glass intended for demanding piping applications.
