Ideal for heavy-duty and passenger vehicle applications requiring reliable clutch performance.
Product Advantage
1. Precision Engineering for Flawless Fit
Crafted from 6061-T6 aerospace-grade aluminum, this master cylinder undergoes CNC milling with a tight ±0.01mm tolerance—ensuring seamless integration with hydraulic systems. Its lightweight yet rigid design reduces unsprung weight by 15% while enhancing vibration damping, outperforming steel counterparts in long-term stability. Ideal for applications demanding exacting dimensional accuracy.
2. High-Performance Hydraulic Delivery
Engineered to handle 12MPa max pressure with a rapid <0.15s response time, it maintains consistent fluid flow under heavy loads. Compliant with SAE J1154 standards, our proprietary piston design minimizes pressure drop by 20% during clutch engagement—cutting slippage and improving shift predictability. Trusted by mechanics for smooth, reliable operation.
3. Wear-Resistant & Corrosion-Proof Durability
Surface-treated with a 25μm hard-anodized layer and sealed with Viton® O-rings, it survives 100,000+ cyclic fatigue tests without leakage (validated by SGS). The corrosion-resistant finish protects against extreme temperatures (-40°C to 120°C), extending service life by 40% vs. uncoated cylinders. A workhorse for heavy-duty use.
4. Proven OEM-Grade Quality
Backed by 8+ years of OEM partnerships with leading automotive brands, we’ve produced over 500,000 units of this cylinder. Our ISO 9001-certified facility follows PPAP/APQP protocols, guaranteeing batch-to-batch consistency and dimensional precision. Get OEM-level reliability at accessible pricing—no compromises on quality.
5. Universal Compatibility for Easy Installation
Designed with a standard 10mm bore and universal mounting pattern, it fits most aftermarket/OEM hydraulic setups. Installation time is reduced by 15% vs. non-standard units, simplifying jobs for technicians and DIYers. Compliant with EU E-Mark for hassle-free global distribution.

Product Uses
Here are specific application scenarios of Clutch Master Cylinder:
1. Aftermarket Replacement for Worn Hydraulic Systems
Ideal for replacing degraded factory units, this cylinder fixes common issues like fluid leaks or slow clutch response. Validated via 100,000+ cyclic tests (SGS-certified) and compliant with ISO 16231-1, it restores smooth gear shifts and eliminates premature wear. Backed by 8+ years of aftermarket demand, it’s a cost-effective fix for drivers seeking factory-grade reliability without overhauling entire hydraulic systems.
2. Commercial Fleet Maintenance & Downtime Reduction
Designed for high-utilization fleets, its 25μm hard-anodized finish and Viton® seals withstand -40°C to 120°C extremes. With 100,000+ cycle durability, it cuts maintenance frequency by up to 30%—minimizing downtime and boosting operational efficiency. Trusted by logistics providers for keeping vehicles on the road longer, it’s a workhorse for fleets prioritizing uptime.
3. OEM-Compliant Drop-In Integration
Leveraging 8+ years of OEM partnerships, this cylinder matches original factory dimensions (±0.02mm bore tolerance) and PPAP protocols. It serves as a direct replacement for brand-specific units, enabling aftermarket sellers to offer OEM-quality solutions without tooling costs. ISO 9001-certified consistency guarantees batch-to-batch reliability for B2B buyers.
Product Operate Guide
Before install, confirm bore diameter (10mm ±0.02mm) and mounting pattern align with your system. Tighten mounts with a 12-15Nm torque wrench (SAE-recommended) to prevent damage. Fill with DOT 3/4 brake fluid, then bleed air per ISO 16231-1—this guarantees <0.15s clutch response. Post-setup, inspect for leaks; our Viton® seals (SGS-tested) resist wear for 100,000+ cycles. Regular fluid checks extend longevity.
