Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation to confirm the seal matches the application. Inspect the sealing surface for scoring, corrosion, or debris, and clean the bore thoroughly so the new seal seats evenly. Use proper installation tools to avoid distorting the nitrile lip or damaging the seal edge during press-in.
