Applications
This kit is ideal for use in industrial finishing systems, airless spray rigs and fluid-handling modules where seal integrity is critical. By replacing worn or degraded packings and O-rings with the 104712 kit, equipment maintains performance specification, prevents leakage and reduces service-related downtime.
Performance Advantages
- Ensures tight sealing and prevents fluid leakage even under heavy cycle conditions.
- Maintains system pressure and stabilises output by using correct OEM seal elements.
- Reduces maintenance complexity by providing a complete kit rather than individual seals.
- Extends equipment life by replacing wear elements proactively.
- Helps retain system calibration and quality by maintaining designed seal clearances.
Maintenance Tips
During service intervals, clean all sealing surfaces thoroughly, remove any residue or debris, then install the new O-rings and packing components from the kit. Confirm proper fit and orientation, apply approved lubricants if required, and test the system under normal operating pressures before full production to ensure leak-free operation.
Frequently Asked Questions
It contains a complete set of O-rings and packing seals specified for the relevant Graco equipment to restore sealing performance and prevent leaks.
Install this kit during routine preventive maintenance or when you observe signs of seal wear, fluid seepage, or pressure loss in the system.
Re-using old O-rings is not recommended since they may have deformed or degraded. For best performance, use the new seal elements provided in the kit.
