Description
The Webster 1000377 Priming Tool oil safety valve is used in heat elements, including oil furnaces, oil boilers, and burner assemblies, to aid in fuel line priming during the maintenance or start-up process in HVAC systems. It is attached to the oil safety valve and temporarily forces it open, allowing fuel oil to flow through the line and providing the burner pump with the correct flow during the priming process. It assists in oil delivery by using systems, based on vacuum-activated safety valves and supply pressures.
