Product Information
Product Information
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.
Sold Each.
x2 Required Per Car.


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.

About Reservoir / Tank

High-Quality Hydraulic Reservoirs & Tanks for Stable, Reliable Brake & Clutch Performance

Hydraulic reservoirs—also known as fluid tanks or expansion containers—store and supply hydraulic fluid for brake and clutch systems. These reservoirs ensure a stable fluid level, maintain pressure balance and prevent air from entering the hydraulic circuits. Whether used in performance vehicles, classic models or daily drivers, the reservoir plays a crucial role in keeping hydraulic systems responsive, consistent and safe.

A healthy reservoir ensures the brake and clutch systems always receive the correct amount of fluid, preventing pressure loss, contamination and system failure.

What Hydraulic Reservoirs & Tanks Do

Reservoirs and hydraulic tanks support the system by:

  • Storing brake or clutch fluid for use by the master cylinder
  • Maintaining correct fluid levels during temperature and pressure changes
  • Allowing fluid expansion to avoid over-pressurisation
  • Preventing air entry into the hydraulic system
  • Reducing contamination via filtered caps or sealed designs
  • Supporting consistent pedal feel during demanding conditions

A reliable reservoir helps ensure stable braking and clutch engagement across all temperatures and driving environments.

Why Hydraulic Reservoirs Commonly Fail

Despite being simple components, reservoirs are exposed to heat, vibration and corrosive fluids. Over time, they may deteriorate or fail due to:

  • Cracking or brittleness from age and UV exposure
  • Internal contamination from degraded seals or old fluid
  • Leaks caused by stress fractures or weakened hose connections
  • Discolouration or clouding, making fluid levels hard to read
  • Warped or loose caps leading to air entry
  • Corrosion on metal mounting points or fittings
  • Heat-related deformation reducing sealing effectiveness

Typical symptoms include fluid loss, soft pedal feel, brake warning lights, or inconsistent clutch operation.

Why You Should Replace a Worn or Damaged Hydraulic Reservoir

Replacing an old or failing reservoir with a high-quality, precision-built alternative designed to match original hydraulic performance ensures your vehicle’s braking and clutch systems remain safe and dependable.

Benefits include:

  • Restored fluid capacity and pressure stability
  • Clear fluid visibility for accurate level checks
  • Prevention of leaks and air ingress
  • More consistent pedal feel in brake and clutch systems
  • Reduced risk of contamination and hydraulic failure
  • Improved long-term safety and reliability

A new reservoir is a simple, cost-effective upgrade that protects the entire hydraulic system.
