Prime rod kit for Graco L100CM

The prime rod kit facilitates the priming process in Graco pumping and spray systems. This component assists in establishing the initial flow of fluid through the pump by removing air from the system, which prepares the equipment for operation. It is used in systems designed for the application of polyurethane foam and polyurea in construction and industrial coating applications.

This kit is compatible with Graco L100CM and L100CS models. The assembly includes the primary rod along with necessary seals and gaskets required for installation and operation within the pump assembly. Proper installation of these components ensures the system maintains the necessary seal effectiveness during the priming cycle.

Prime rods serve as a manual or mechanical interface to actuate the priming valve, allowing fluid to bypass the main discharge line until the pump is fully primed and air is purged. This function is necessary to ensure that the pump can move viscous materials consistently once the system is pressurized. Regular inspection of the rod and associated seals helps maintain the operational readiness of the pump system.
