Information
Clutch fluid hose - Clutch master cylinder to fluid pipe - for Left hand drive cars.
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.

Constructed from premium reinforced rubber with high-strength internal layers and corrosion-resistant end fittings, the hose is engineered to withstand high hydraulic pressures, brake fluid exposure, temperature fluctuations and constant vibration. Its flexible design helps maintain consistent clutch operation while ensuring a secure, leak-free connection within the clutch hydraulic circuit.
What This Product Does:
- Transfers hydraulic fluid from the clutch master cylinder through the clutch hydraulic system.
- Maintains consistent hydraulic pressure for clutch operation.
- Accommodates engine and transmission movement.
- Provides a flexible, leak-free hydraulic connection.
- Supports smooth clutch engagement and disengagement.
- Helps maintain a consistent clutch pedal feel.
- Ensures reliable hydraulic system performance.
- Forms an essential part of the clutch hydraulic circuit.
Symptoms Of Wear Or Failure:
- Hydraulic fluid leaks around the hose or fittings.
- Soft or spongy clutch pedal.
- Clutch pedal sinking towards the floor.
- Difficulty selecting gears.
- Inconsistent clutch engagement or disengagement.
- Visible cracks, bulges or deterioration in the hose.
- Fluid contamination around hose connections.
- Reduced hydraulic pressure within the clutch system.
- Air entering the hydraulic circuit.
- Complete loss of clutch operation in severe cases.
Why Replacement Matters:
- The clutch master cylinder flexi hose operates under constant hydraulic pressure and is exposed to brake fluid, engine heat, vibration and environmental ageing. Over time, the rubber can harden, crack or deteriorate internally, while the reinforced layers may weaken, increasing the risk of fluid leaks or restricted hydraulic flow.
- A failing hydraulic hose can reduce clutch pressure, resulting in poor pedal feel, difficult gear changes and incomplete clutch disengagement. If left unresolved, complete hydraulic failure may occur, preventing the clutch from operating correctly and potentially leaving the vehicle undriveable.
- Replacing a worn or damaged clutch flexi hose restores proper hydraulic pressure and reliable clutch operation. An OE Match replacement provides factory-style fitment, dependable sealing performance and long-lasting durability, helping maintain smooth gear changes and the reliable driving experience expected from your Porsche.
