Applications
The Graco 104712 Packing, O-Ring kit is used in industrial finishing equipment, airless spray rigs and high-flow fluid modules where seals must be replaced during maintenance to preserve performance. By using the correct kit, operators ensure their systems continue to operate to specification, with minimal leakage and consistent output.
Performance Advantages
- Protects against fluid leaks and system downtime by ensuring correct sealing.
- Maintains system accuracy, pressure stability and performance under load.
- Improves reliability by replacing worn seals with OEM-matched parts.
- Reduces maintenance complexity by offering a complete kit rather than individual parts.
- Supports long equipment service life and reduces unexpected failures.
Maintenance Tips
During scheduled maintenance, clean the sealing grooves and mating surfaces thoroughly before installing the new O-rings and packings from the 104712 kit. Ensure proper lubrication if required, verify correct seating and alignment, apply correct torque, and test the system under normal operating pressure to confirm no leakage before returning to production.
Frequently Asked Questions
It contains a set of O-rings and packing seals specified for select Graco assemblies, aimed at restoring correct seal function and preventing leakage.
Install during routine preventive maintenance, or when you detect signs of seal wear, fluid seepage, or loss of system pressure in the associated equipment.
Reusing old O-rings is not recommended because wear, deformation and chemical exposure can compromise seal integrity — replacing with the full 104712 kit ensures optimal performance.
It fits those Graco machines specified in the Compatible Machines list. Always confirm your model number and service manual to verify compatibility before installation.
