A clutch that is engaged/disengaged via hydraulic fluid instead of a cable uses a Clutch Master and Clutch Slave Cylinder. When depressing the clutch pedal a lever is squeezed, forcing hydraulic fluid through hydraulic lines to a "slave cylinder" which houses a piston. The piston forces a push rod to engage or disengage the clutch. A clutch master cylinder that contains the hydraulic fluid sits on a support har near the clutch lever. When either the Master or Slave Cylinder fail the clutch is unable to be disengaged.

OE Match Clutch Slave Cylinder Seal Kit
The OE Match Clutch Slave Cylinder Seal Kit is
designed to overhaul the original hydraulic clutch slave cylinder fitted to the
Porsche 996 and 997 turbo.
Fits:
- Porsche 996 TURBO 2000-05
- Porsche 997 MK1 TURBO 2007-09
- Porsche 997 MKII Turbo 2010-13
Seals for diagram Ref No 1
This repair kit replaces the internal seals and O-rings without requiring replacement of the complete slave cylinder.
The upgraded seals feature improved geometry and materials, designed to provide better sealing performance and reduce hydraulic fluid leaks, particularly in colder climates.
What Does It Do?
The clutch slave cylinder uses hydraulic pressure to operate the clutch release mechanism.
This repair kit renews the internal sealing components, helping maintain hydraulic pressure and reliable clutch operation.
Why Does It Fail?
Common causes include:
- Ageing or hardened internal seals
- Deteriorated O-rings
- Hydraulic fluid leakage
- Temperature-related seal contraction
- Internal cylinder wear or corrosion
When Should It Be Replaced?
Replace the seals if you notice hydraulic fluid leaks, reduced clutch operation or deterioration of the original sealing components.
Preventative replacement is also recommended
during clutch replacement or engine-out servicing.
Kit Contents
- Nine replacement internal seals and O-rings
- O-ring identification template
- O-ring location guide
- Written installation instructions
Installation Notes
The original slave cylinder must be dismantled and inspected before fitting the replacement seals.
Follow the supplied installation instructions and bleed the hydraulic clutch system after reassembly. A damaged or corroded cylinder bore may require complete cylinder replacement.
Porsche 996 & 997 Turbo Clutch Slave Cylinder Repair Parts
The Porsche 996 and 997 Turbo hydraulic clutch systems rely on correctly functioning internal seals to maintain pressure and ensure reliable clutch operation.
This OE Match repair kit provides replacement seals and O-rings for refurbishing compatible original clutch slave cylinders, offering an alternative to replacing the complete assembly.

OEMatch Clutch Slave Cylinder — Engagement, Smoothness, Control
OEMatch clutch slave cylinders restore correct hydraulic operation within the clutch system on Porsche models. The slave cylinder converts hydraulic pressure from the master cylinder into mechanical movement to disengage the clutch, allowing smooth gear changes and consistent pedal feel. OEMatch supplies components and kits suitable for restoration and routine maintenance on both classic and modern Porsche vehicles.
Available Types
- Complete replacement slave cylinders
- Seal and rebuild kits for hydraulic overhaul
- Complete assemblies suited to classic and modern Porsche applications
Understanding OEMatch Clutch Slave Cylinder
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original clutch slave cylinder.
OE (Original Equipment) refers to parts matching original specifications for the clutch slave cylinder and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM clutch slave cylinders engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The clutch slave cylinder is the final hydraulic actuator in the system. When the driver depresses the clutch pedal the master cylinder pressurises fluid which the slave cylinder converts into linear movement to operate the release mechanism. Typical construction uses a precision bore, piston and seals; attention to seal condition and corrosion resistance is important to maintain pressure and prevent leaks.
Benefits Include
- Restores consistent pedal feel and reliable disengagement
- Reduces the risk of fluid leaks and contamination
- Supports smooth, accurate gear changes and driver control
Why Clutch Slave Cylinder Wear and Fail
- Seal wear and deterioration allowing fluid leaks
- Corrosion from moisture-contaminated hydraulic fluid
- Mechanical damage or material fatigue from heat and vibration
The Importance of Replacing with OEMatch Clutch Slave Cylinder
Replacing a worn or leaking slave cylinder restores correct hydraulic pressure and consistent clutch operation on Porsche models. Timely replacement helps avoid sudden loss of clutch function, maintains shift accuracy and preserves other hydraulic components. For many repair tasks, renewing seals or the complete cylinder prevents recurrent issues and supports long-term system reliability.
Advantages
- Precision manufacture and high-quality sealing materials for durable operation
- Corrosion-resistant finishes and components selected for hydraulic service
- Options suitable for both restoration projects and routine maintenance on Porsche vehicles
Support & Advice
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified and confirm correct bleed procedures for the hydraulic system after fitting.
