Check for Special Features: Some metal push to connect fittings may have additional locking mechanisms for extra security in high-pressure applications. Ensure these are fully disengaged before attempting removal.

Inspect for Wear or Damage: After removal, inspect both the fitting and the tubing for any signs of wear or damage. Metal fittings, while durable, can still suffer from fatigue or corrosion depending on the environment.

Lubricate if Reusing: If you plan to reuse the fitting, applying a small amount of appropriate lubricant to the O-ring can ensure a better seal when reinserted. Ensure the lubricant is compatible with the system’s fluids and materials.
