Which of the following is NOT considered a hanging hardware component?

The shear valve is not classified as a hanging hardware component because it serves a different purpose within the fuel dispensing system. Typically, hanging hardware components are those that are directly involved in the delivery of fuel through a dispenser to a vehicle, and that are physically suspended from the fuel delivery arm. This includes items like nozzles, swivels, and whip hoses, which collectively facilitate the dispensing process.

In contrast, the shear valve functions primarily as a safety device designed to prevent product spillage if there is a break in the delivery system, separating the underground storage tanks from the nozzle and piping. Its main purpose is to mitigate the risks associated with spills, making it essential for safety but not for the actual dispensing process. Understanding the distinction between these components helps clarify the roles they play in ensuring safe and efficient fuel delivery.
