Is Indicator Pin Cap 1-11519 a Wear Part?

Yes — the Indicator Pin Cap 1-11519 is considered a semi-wear part.
Although it does not directly participate in high-pressure fluid flow, it is exposed to vibration, environmental conditions, repeated maintenance handling, and mechanical stress. Over time, it may become loose, cracked, deformed, or lose its protective effectiveness.
If not replaced when worn, it can lead to contamination of internal components or inaccurate indicator function.
Regular inspection during maintenance is strongly recommended.
