Molub-Alloy Paste White T – High Performance Assembly & Anti-Fretting Paste
Molub-Alloy Paste White T is a premium high-performance assembly paste designed to provide exceptional protection against fretting corrosion, stick-slip, wear, and seizure in demanding automotive, industrial, and workshop applications.
This white assembly paste applies cleanly and appears almost colourless when spread as a thin layer, making it ideal for precision assembly work where cleanliness and protection are equally important.
Formulated for universal assembly and thin-film lubrication applications, Molub-Alloy Paste White T helps simplify component assembly and future disassembly while protecting contact surfaces against corrosion, vibration-related wear, and moisture ingress.
Its advanced formulation provides excellent resistance to both hot and cold water while delivering long-lasting corrosion protection under harsh operating conditions.
Particularly effective in applications exposed to vibration and frictional movement, the paste helps prevent fretting corrosion and reduces stick-slip behaviour, making it ideal for hydraulic cylinders, open lubrication points, threaded assemblies, sliding surfaces, and mechanical components subject to oscillating movement.
The product also helps eliminate squeaking noises and improves smooth operation in moving assemblies exposed to high loads and thermal stress.
Suitable for temperatures ranging from -30°C to +250°C, Molub-Alloy Paste White T delivers reliable lubrication and anti-corrosion performance across a wide range of workshop, automotive, and engineering environments.

Porsche Clutch Master Cylinders | Hydraulic Precision for Smooth Gear Engagement
The clutch master cylinder is a key component of your Porsche’s hydraulic clutch system. It converts pedal pressure into hydraulic force, sending fluid to the slave cylinder to engage or disengage the clutch. A properly functioning clutch master cylinder ensures smooth gear shifts, precise pedal feel, and reliable performance in every driving condition.
At Design911, we supply premium clutch master cylinders engineered to meet or exceed original performance standards. Built using high-grade materials and precision internal seals, each unit delivers consistent hydraulic pressure, long-term durability, and excellent pedal response.
Whether you’re restoring a classic Porsche or maintaining a modern model, our clutch master cylinders guarantee the performance, precision, and reliability your drivetrain demands.
What Does a Clutch Master Cylinder Do?
The clutch master cylinder forms the first stage of your Porsche’s hydraulic clutch system, transmitting driver input into fluid pressure for gear engagement.
Core Functions:
- Converts pedal movement into hydraulic pressure.
- Delivers fluid to the clutch slave cylinder for smooth disengagement.
- Ensures accurate clutch engagement for seamless gear shifts.
- Maintains pedal feel and consistent hydraulic response.
- Supports high-performance driving with precise modulation.
Without a fully functioning master cylinder, the clutch cannot disengage properly, leading to difficulty selecting gears or complete transmission failure.
Why Do Clutch Master Cylinders Fail or Wear Out?
Over time, hydraulic components experience wear from pressure cycles, fluid contamination, and heat exposure — eventually reducing clutch performance.
Common Causes of Failure Include:
- Internal seal wear or leakage.
- Corrosion from moisture in hydraulic fluid.
- Air ingress into the hydraulic system.
- Damaged piston or bore from debris or age.
- Fluid contamination reducing hydraulic efficiency.
When the master cylinder begins to fail, symptoms may include a soft or sinking clutch pedal, fluid leaks near the pedal, or difficulty shifting gears.
Why Replace Your Porsche Clutch Master Cylinder?
Replacing a worn or leaking clutch master cylinder restores precise pedal pressure, smooth gear changes, and long-term hydraulic reliability.
Key Benefits:
- Restores responsive clutch operation and pedal feel.
- Prevents clutch drag, slippage, or missed gear shifts.
- Ensures stable hydraulic pressure across the system.
- Reduces risk of air or fluid leaks in the clutch circuit.
- Compatible with Porsche 911, Cayman, Boxster, Panamera, Macan, and classic models.
- Ideal for daily driving, restorations, and motorsport applications.
For best performance, always replace clutch fluid and inspect the slave cylinder when fitting a new master cylinder.
Highlights
- Precision-engineered Porsche clutch master cylinders.
- Corrosion-resistant construction for long service life.
- Consistent hydraulic performance under pressure.
- Direct-fit replacement for Porsche clutch systems.
- Designed for reliability, responsiveness, and smooth shifting.
- Suitable for restoration, maintenance, or performance use.
