The clutch hydraulic hose is a replacement line for use on classic Porsche 924 and 944 series vehicles. This part replaces the factory flexible hose running between the clutch master cylinder and the fluid pipe. Engineered to match Porsche’s original specifications, the hose features a correct inner diameter, rubber construction rated for high hydraulic pressure, and correct end fittings and flare connections for a direct-fit installation.
Fits:
For LHD (Left hand drive) cars
Porsche 924 2.0L-2.5L 1975 - 1989
Porsche 944 2.5L-3.0L 1981 - 1991 (not turbo)
Diagram ref no 22
A deteriorated clutch hose can lead to reduced hydraulic pressure, resulting in a soft or inconsistent pedal, delayed clutch engagement or incomplete release. This not only affects driving feel but can contribute to accelerated wear of clutch components. Replacing with a correct hose restores fluid path integrity and ensures your clutch system performs as designed.
When to replace:
• Clutch pedal feels soft, spongy or inconsistent.
• Visible age-related cracks, swelling or bulging of the existing hose.
• Evidence of fluid leakage around hose ends or fittings.
• When the clutch hydraulics have been opened for service, or during clutch replacement.

OEMatch clutch master cylinders for Porsche models restore consistent pedal feel and reliable hydraulic pressure across classic and modern vehicles. These units support smooth gear changes and predictable pedal modulation. OEMatch Clutch Master Cylinder components are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable.
Available Types- Replacement clutch master cylinders for direct fit where applicable
- Master cylinder repair kits for seal and bore restoration
- Reconditioned or remanufactured units where specified
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original clutch master cylinders.
OE (Original Equipment) refers to parts matching original specifications for the clutch master cylinders and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM clutch master cylinders engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The clutch master cylinder converts pedal movement into hydraulic pressure, sending fluid to the slave cylinder to engage or disengage the clutch. Properly sized bores and sealing components maintain pedal feel and system pressure; when seals deteriorate or fluid becomes contaminated, hydraulic performance falls and gear selection can become difficult. OEMatch focuses on clutch master cylinder-related items selected for Porsche applications, offering replacement units and repair kits suited to restoration and routine maintenance.
- Restored pedal feel and predictable hydraulic response
- Reduced risk of fluid leakage and air ingress
- Supports consistent gear engagement during normal and spirited driving
- Internal seal deterioration from age and fluid contamination
- Corrosion of bore or piston surfaces caused by moisture in hydraulic fluid
- Air ingress or debris entering the circuit, reducing pressure and modulation
Replacing a worn or leaking master cylinder restores stable hydraulic pressure and reduces the risk of clutch drag, slippage or missed gear changes. When fitting a new unit, replace the fluid, fully bleed the system and inspect the slave cylinder and hydraulic lines for wear or leaks. Choosing a correctly dimensioned replacement helps preserve pedal modulation and drivability for Porsche models.
Advantages- Manufactured to original-spec dimensions and tolerances for consistent fit
- Compatible with factory systems and sensors where present
- Available as complete units or service kits to suit restoration or maintenance tasks
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.
