The ECS Billet Master Cylinder Fitting is the ultimate solution for a notorious failure point in BMW E30 clutch systems. This critical fitting, located at the end of the master cylinder reservoir hose, is responsible for delivering hydraulic fluid to the clutch master cylinder inlet. Unfortunately, the OEM plastic fitting is prone to degradation after prolonged exposure to brake fluid, often leading to total hydraulic pressure loss and brake fluid leaks inside your vehicle.

ECS has addressed this issue by engineering a robust and long-lasting alternative. Crafted from 6061 billet aluminum and finished with black hard-coat anodizing for superior corrosion resistance, this precision-machined fitting replaces the fragile plastic original, ensuring leak-free performance for the lifetime of your vehicle. Upgrade to our Billet Master Cylinder Fitting during your next clutch master cylinder service and enjoy peace of mind knowing your BMW is equipped with a durable, high-quality solution.

Features & Benefits:

Made from 6061 billet aluminum for a permanent, reliable upgrade over the factory plastic fitting. Black hard-coat anodized finish ensures long-lasting protection against the elements. Precision-machined barbs match OEM dimensions for a leak-free seal with Genuine and aftermarket master cylinders. Designed for a secure fit within the factory grommet location. Prevents brake fluid leaks and loss of clutch hydraulic pressure caused by plastic fitting failure. Upgrade your BMW and bulletproof your master cylinder with the ECS Billet Aluminum Master Cylinder Fitting. Ensure clutch hydraulic system reliability and enjoy peace of mind knowing your failure-prone plastic master cylinder fitting has been addressed.

Over time, these units can wear out and develop an annoying squeak when the pedal is pressed. Responsible for transferring fluid to the slave cylinder to engage and disengage the clutch, a worn unit can affect pedal feel and performance. Swap yours out and eliminate that pesky squeaky piston for good.
