Power Steering Reservoir O-Ring & Clamp AD10. Porsche 996 GT3 CUP.

O-Ring & Clamp AD10.
This genuine Porsche O-Ring & Clamp AD10 kit is a small but essential hydraulic sealing component used in various Porsche steering-assist and hydraulic line applications. Designed to maintain a leak-free, high-pressure connection, this kit is commonly used in models such as the Porsche 996 GT3 Cup and other Porsche vehicles equipped with similar hydraulic fittings.

Fits:

• Porsche 996 GT3 CUP

What This Product Does:

• The kit seals and secures a hydraulic connection — likely a hose or pipe attached to the power steering system or a steering‐related hydraulic line.
• The O-ring ensures a fluid‐tight seal preventing leaks of hydraulic fluid (such as power‐steering fluid) at the connection point.
• The clamp (or similar securing element) ensures the hose or fitting is mechanically retained, preventing movement, loosening or vibration under pressure.
• Essentially, it helps maintain hydraulic pressure, fluid integrity, and the overall reliability of the steering‐assist / hydraulic system.

Symptoms Of Failure:

• Power-steering fluid leak at the steering rack, pump, or hoses — especially around fitting points.
• Loss of steering assist (i.e., heavier steering input) because fluid is leaking or system pressure is reduced.
• Whining or groaning from the power-steering pump (air ingress due to low fluid) or bubbling sounds while turning.
• Visible damage to the clamp or fitting: missing clamp, loose hose, degraded or cracked O-ring seal.
• Steering feel deteriorates or becomes inconsistent — for example, steering effort increases when cold or after the car sits.
• In race/track applications (e.g., 996 GT3 Cup) a sudden steering assist drop mid‐session could be catastrophic.

Why Replacement Matters:

• Safety: Steering is a critical control system. A leak or failure in the power‐steering line can compromise control, especially under high loads or in a high‐performance car.
  
• Performance & Reliability: In Porsche performance or racing vehicles, maintaining full hydraulic integrity is essential. This small part helps ensure the system works as designed.
  
• Prevention: A failed O-ring or loose clamp may lead to a minor leak initially, but over time it can cause larger failures – pump wear, fluid starvation, overheating, or loss of assist. Replacing proactively avoids bigger repairs.
  
• Fit & Spec: Using the correct genuine Porsche part ensures proper size, material, and clamp strength — critical in high‐performance/hydraulic environments.
  
• Cost-Effectiveness: The kit is a low‐cost part compared to full hydraulic system repairs or steering rack replacement.
  
• Track/High-Load Use: Especially in dedicated race or performance cars (996 GT3 Cup, track‐modified vehicles) minor leaks or fitting failures can lead to major issues mid‐session.
