The Graco 25U534 Kit, Conversion, Grease Cup, 105 is a genuine OEM conversion kit developed to upgrade older Z-Series chemical pumps that were originally manufactured without a grease cup or that utilize an obsolete wet cup arrangement. The kit replaces the complete throat seal and cup assembly with an updated grease cup configuration, improving lubrication and simplifying ongoing maintenance.
Designed specifically for Pump Size 105 applications, this conversion kit provides a practical solution when older throat seal components require replacement. Instead of sourcing discontinued individual parts, users can install the complete conversion assembly and update the pump to the current service design.
This conversion kit is commonly used during pump rebuilds or maintenance procedures when obsolete throat seal components can no longer be serviced individually. The updated grease cup arrangement helps protect critical sealing surfaces from contamination while providing a more service-friendly design for demanding adhesive and sealant pumping applications.
