User Guide
Installation & Maintenance Guide
Installation Instructions
Check the O-Ring
Before installation, check the O Ring for surface defects, cracks, deformation, or contamination. Ensure the size and material are suitable for the application.
Clean the Sealing Area
Clean the groove, sealing surface, and surrounding components to remove dust, oil, metal particles, and other contaminants.
Apply Lubrication
Apply a suitable lubricant compatible with rubber to reduce friction and prevent damage during installation. Avoid petroleum-based lubricants.
Install Carefully
Place the O-Ring into the groove evenly. Avoid twisting, stretching excessively, or cutting the sealing ring during installation.
Check Assembly
Ensure the O-Ring is properly positioned and not pinched or displaced before system operation.
Perform Testing
After installation, conduct pressure testing or leakage inspection to confirm sealing performance.
Maintenance Recommendations
Regular Inspection
Periodically check the O-Ring for wear, aging, cracks, hardening, or deformation.
Keep Clean
Prevent dust, particles, and chemical contamination from damaging the sealing surface.
Avoid Improper Media
Do not expose O-Rings to petroleum oils, mineral oils, fuels, or hydrocarbon solvents.
Monitor Working Conditions
Ensure operating temperature, pressure, and chemical environment are within the recommended range.
Replace When Necessary
Replace the O-Ring if leakage, permanent deformation, surface damage, or loss of elasticity occurs.
Proper Storage
Store in a cool, dry place away from direct sunlight, ozone sources, heat, and chemicals.
