Pressure accumulator. Porsche 993TT / 996 TT / 997TT › 99731416600
- Porsche 993 (911) TURBO 1994-96
- Porsche 996 TURBO 2000-05
- Porsche 996 GT2 2001-05
- Porsche 997 MK1 TURBO 2007-09
- Porsche 997 MK1 GT2 2007-09
This original Porsche pressure accumulator, also known as a pressure unit, forms part of the clutch hydraulic operating system and helps maintain stable hydraulic pressure for correct clutch operation.
Fits:
Porsche 993 Turbo 1994 - 1998
Porsche 996 Turbo / GT2 2000 - 2005
Porsche 997 Turbo / GT2 2007 - 2009
Diagram ref no 28
This component is used on selected Porsche Turbo clutch hydraulic systems, including 993TT, 996TT and 997TT applications.
What This Part Does / Functions
• Stores hydraulic pressure within the clutch operating system
• Helps support smooth and consistent clutch operation
• Assists the clutch slave cylinder hydraulic circuit
• Helps maintain stable pressure during clutch actuation
• Supports correct clutch engagement and disengagement
• Replaces a weak, faulty, leaking or failed pressure accumulator
• Provides correct OE Porsche hydraulic specification and fitment
• Supports reliable operation of the factory clutch hydraulic system.
Why Replace This Part?
The pressure accumulator is a hydraulic component that can weaken or fail over time due to internal diaphragm wear, pressure cycling, age, fluid condition or seal deterioration. If the accumulator no longer stores pressure correctly, the clutch hydraulic system may not operate as intended. Replacing it with an OE Genuine Porsche pressure accumulator helps restore correct hydraulic pressure reserve and supports reliable clutch operation on high-performance Turbo models.
Common Symptoms of a Faulty Pressure Accumulator
• Heavy, inconsistent or abnormal clutch pedal feel
• Difficulty selecting gears
• Clutch engagement or disengagement issues
• Hydraulic pressure loss in the clutch system
• Clutch slave cylinder operating faults
• Fluid leakage around the accumulator or hydraulic fittings
• Reduced clutch system response
• Fault confirmed during hydraulic clutch system diagnosis.
When to Replace This Part
• If the clutch hydraulic system is not holding pressure correctly
• If clutch operation becomes inconsistent or difficult
• If the accumulator is leaking or damaged
• During clutch slave cylinder or hydraulic line repair
• During gearbox or clutch system overhaul
• If hydraulic pressure testing confirms accumulator failure
Where It Fits on the Car
This pressure accumulator fits within the clutch hydraulic operating system, associated with the clutch slave cylinder / pressure line circuit on selected Porsche Turbo models.
Correct installation and bleeding procedures must always be followed. Clutch hydraulic components are critical to vehicle operation and should be fitted by a qualified technician.

This original Porsche pressure accumulator, also known as a pressure unit, forms part of the hydraulic brake / ABS control system and helps store hydraulic pressure for correct system operation.
Fits:
Porsche 964 C4 / RS
Porsche 964 Turbo Look C2 / C4
Diagram ref no 24
This component is used within the Porsche 964 hydraulic brake / ABS control system on selected Carrera 4, RS and Turbo Look applications.
What This Part Does / Functions
• Stores hydraulic pressure within the brake / ABS system
• Helps support correct hydraulic system operation
• Assists pressure availability for the anti-lock braking system
• Works with the hydraulic unit and associated control components
• Helps maintain consistent braking system response
• Replaces a weak, faulty or leaking pressure accumulator
• Provides correct OE Porsche fitment and hydraulic specification
• Supports proper operation of the factory brake hydraulic system.
Why Replace This Part?
The pressure accumulator is a hydraulic component that can weaken or fail over time due to age, internal diaphragm wear, pressure cycling or fluid system contamination. A failing accumulator may not store pressure correctly, which can affect brake system operation and ABS hydraulic response. Replacing it with an OE Genuine Porsche pressure accumulator helps restore correct hydraulic pressure storage and supports reliable brake system function.
Common Symptoms of a Faulty Pressure Accumulator
• ABS or brake system warning light
• Brake hydraulic pressure faults
• Pump running too frequently
• Hard or inconsistent brake pedal feel
• Reduced hydraulic pressure reserve
• Brake system fault codes
• Hydraulic fluid leakage around the accumulator area
• Fault confirmed during brake hydraulic system diagnosis.
When to Replace This Part
• If hydraulic pressure storage is weak or inconsistent
• If the brake / ABS pump cycles excessively
• If brake or ABS warnings are present.
• If the pressure accumulator is leaking or damaged
• During hydraulic unit or ABS system repair
• During brake system overhaul or restoration
• If the accumulator fails pressure testing
• When restoring the braking system with OE Genuine Porsche parts.
Where It Fits on the Car
This pressure accumulator fits within the hydraulic brake / ABS control system. It is associated with the hydraulic unit / anti-lock brake system control assembly on the Porsche 964.
Correct installation and brake hydraulic system procedures should always be followed. Brake hydraulic components are safety-critical and should be fitted by a qualified technician.
