When to Replace Gladhand Seals
As a rule, you should replace Gladhand Seals every year. But if you see signs of damage or wear beforehand, replace them immediately.

- A new set of seals
Step #1: Remove the Old Seal: Insert your screwdriver behind the old seal and pop it out.
Step #2: Clean Gladhand: Once the old seal is removed, clean the gladhand cavity with a rag until it’s free of debris and oil.
Step #3: Insert New Seal:
- Insert the new seal and, using your fingers, press around the seal’s surface until its grooves lock into the grooves of the gladhand.
- Once the seal is properly seated, reattach the couple and turn the pressure on to check for leaks.
