Recommendation

• Replace this O-ring if hydraulic fluid leakage, wear, or seal degradation is detected.

• For a more thorough maintenance solution, consider the complete locking cap assembly (P/N?4185045)—includes O-rings, cover, key, and hardware, ideal when multiple components show wear 

• Keep a spare O-ring in stock—it’s a low-cost yet essential part that ensures long-term reliability of your gate operator.
