3. Setup and Installation
Proper installation of the gasket is essential for preventing leaks and ensuring optimal blender performance. Only one gasket is needed per blender.
Installation Steps:
- Disassemble the Blender Blade Assembly: Carefully unscrew and remove the blade assembly from the bottom of your blender jar.
- Remove Old Gasket: Locate the old gasket, which typically sits between the top of the blade and the bottom of the jar. Gently peel it off. Dispose of the old gasket responsibly.
- Clean Surfaces: Thoroughly clean the area where the gasket will sit on both the blade assembly and the jar. Ensure there are no food particles or residue that could compromise the seal.
- Position New Gasket: Place the new Univen gasket onto the blade assembly. The gasket should sit snugly around the base of the blades, forming a tight seal. Refer to Figure 3.1 for proper placement.
- Reassemble Blender: Carefully screw the blade assembly, with the new gasket in place, back onto the bottom of the blender jar. Ensure it is tightened securely but do not overtighten.
- Test for Leaks: Before blending food, fill the jar with a small amount of water and run the blender on a low setting for a few seconds. Check for any leaks around the base of the jar. If leaks occur, re-check the gasket's position and tightness.

4. Operating Considerations
Once installed, the gasket functions automatically to prevent liquid from leaking out of the blender jar during operation. Ensure the gasket is always in place before using your blender.
- Always ensure the gasket is clean and free of debris before each use.
- Confirm the blade assembly is securely fastened to the jar after gasket installation.
5. Maintenance
To prolong the life of your Univen Blender Gasket Seal and maintain optimal performance:
- Regular Cleaning: After each use, remove the gasket and wash it thoroughly with warm, soapy water. Rinse well and allow it to air dry completely before reassembling.
- Inspect for Wear: Periodically inspect the gasket for any signs of wear, cracking, or deformation. A worn gasket can lead to leaks. Replace the gasket if any damage is observed.
- Proper Storage: When not in use, store the gasket with the blender assembly in a clean, dry place.
6. Troubleshooting
Issue: Blender Leaks During Operation
- Possible Cause 1: Gasket is not seated correctly.
Solution: Disassemble the blade and jar, remove the gasket, and re-seat it carefully, ensuring it lies flat and evenly around the blade assembly. Re-tighten the assembly to the jar. - Possible Cause 2: Gasket is worn or damaged.
Solution: Inspect the gasket for cracks, tears, or flattening. If damaged, it needs to be replaced. - Possible Cause 3: Blade assembly is not tightened sufficiently.
Solution: Ensure the blade assembly is securely screwed onto the blender jar. Do not overtighten, but ensure it is firm. - Possible Cause 4: Incorrect gasket size.
Solution: Verify that your blender model is listed in the compatibility section (Section 2). If your model is not listed, this gasket may not be the correct size. Refer to the dimensions provided in Section 2 and compare them to your original gasket or blender specifications.
