The Porsche Pressure Line Between Control Valve and Pressure Accumulator is a genuine OEM hydraulic line designed to ensure proper operation of your differential lock system. This high-pressure line connects the control valve to the pressure accumulator, transferring hydraulic fluid securely and reliably under load.
Fits:
- Porsche 964 (911) C2 1989-93 (5-Speed Gearbox)
- Porsche 964 (911) C4 1989-93 (5-Speed Gearbox)
What This Product Does:
The pressure line is part of the hydraulic system for the locking differential in Porsche models. It connects the control valve to the pressure accumulator, ensuring that hydraulic pressure is properly stored and delivered to the system when needed.
Functions:
- Transfers hydraulic pressure between the control valve and pressure accumulator.
- Maintains reliable operation of the differential lock system.
- Ensures smooth engagement and disengagement of the diff lock under load.
- Designed to withstand high hydraulic pressures without leakage or deformation.
Symptoms Of A Faulty Pressure Line:
- Differential lock not engaging or releasing correctly.
- Hydraulic fluid leaks near the accumulator or valve.
- Warning lights or fault codes related to the diff lock system.
- Reduced traction when the lock fails to operate.
- Visible wear or damage on the line itself.
This pressure line is a high-pressure hydraulic component—if it fails, the differential lock system won’t function correctly, reducing performance and safety. Replacing it with a genuine OEM Porsche line ensures:
- Leak-free and reliable hydraulic pressure transfer.
- Correct fitment within the diff lock hydraulic system.
- Restored function of the accumulator and control valve connection.
- Long-term reliability under demanding driving conditions.

High-Quality Clutch Hoses & Hydraulic Lines for Smooth, Consistent Clutch Performance
Clutch hoses and hydraulic lines play a crucial role in the clutch system, ensuring brake fluid (or hydraulic fluid) reaches the slave cylinder with the correct pressure. These hoses transmit the force generated by the clutch pedal, allowing the clutch to engage and disengage smoothly. A healthy clutch hose ensures precise pedal feel, clean gear changes and reliable performance in both daily driving and high-load conditions.
Whether you are restoring a classic, maintaining a modern performance vehicle or repairing a leaking hydraulic system, high-quality clutch hoses and lines are essential for safe, predictable clutch operation.
What Clutch Hoses and Hydraulic Lines Do
These components support clutch function by:
- Transferring
hydraulic pressure from the master cylinder to the slave cylinder
- Maintaining
consistent fluid flow for smooth clutch engagement
- Ensuring
precise pedal feel, particularly under hard driving
- Withstanding
pressure spikes during quick shifts or spirited acceleration
- Resisting
expansion, especially with braided or reinforced hose upgrades
- Supporting long-term hydraulic system reliability
A properly functioning hydraulic line ensures optimal clutch operation in all driving conditions.
Why Clutch Hoses and Lines Commonly Fail
Clutch hoses operate in high-temperature, high-pressure
environments, and over time they can degrade or fail. Common reasons include:
- Rubber
hose swelling or softening due to age and fluid exposure
- Cracking
or brittleness from heat cycling
- Corrosion
on metal hard lines
- Internal
collapse, restricting fluid flow
- Leaks
caused by worn fittings or degraded seals
- Contamination,
weakening hose material
- Abrasion or physical damage from engine movement or debris
Failure symptoms often include a spongy or soft clutch pedal, difficulty engaging gears, fluid leaks, or complete clutch loss.
Why You Should Replace Worn Clutch Hoses & Lines
Replacing worn or damaged hoses with a high-quality, precision-engineered alternative designed to meet original hydraulic performance standards restores clutch reliability and drivability.
Benefits include:
- Faster, more consistent clutch engagement
- Improved pedal feel and responsiveness
- Reduced risk of hydraulic failure or loss of clutch control
- Enhanced durability in high-temperature conditions
- Better resistance to pressure spikes
- Longer-lasting performance with braided or reinforced hose upgrades
A new clutch hose or line is a cost-effective upgrade that significantly improves safety, shifting quality and overall driving confidence.
