Step 1: Understanding the Material
- Confirm that the O-ring material is suitable for use in contact with food, for example by selecting a EC1935 certified rubber materials.
- Check the chemical and temperature compatibility of the O-ring material with the food substances it will come in contact with, including cleaning agents.
Step 2: Pre-Installation Inspection
- ERIKS o-rings are expected to be supplied in good condition, but a quick visual check of the O-ring for any tears, cuts or abrasions that could affect its integrity.
- Verify that the O-ring size is appropriate for the application to ensure a proper seal.
Step 3: Installation Process
- Ensure that the surface where the O-ring will be placed is clean and free of debris.
- Carefully place the O-ring in its designated groove. Ensure the O-ring is seated properly and evenly in the groove without any twists.
- For o-rings in rod or cylinder applications, it might be useful to use a lubrication to ease the installation. In this case, select a lubricant that is compatible with the rubber material. An incompatible lubricant might affect to rubber material and create leakage. For example don’t use silicone lubricant on silicone o-rings, and don’t use mineral grease on EPDM o-rings.
Step 4: Post-Installation Check
- Once installed, double-check to ensure that the O-ring is correctly seated
- If possible, conduct a test under normal operating conditions to check for leaks or any other issues.
Step 5: Documentation and Compliance
- Document the type of O-ring used (ERIKS article number and ERIKS delivery number), the lubricant applied (if any) and the date of installation for future reference.
Important Considerations
- Ensure that staff responsible for O-ring installation are properly trained in these procedures.
- Have protocols in place for dealing with O-ring failures to minimize contamination risks, for example recognize o-ring damage.
