A21-1602020 OE-Grade High-Strength Stable Clutch Master Cylinder for Chery

Product Introduction

A21-1602020 OE-Grade High-Strength Stable Clutch Master Cylinder for Chery

Product Advantage

1. OE-Grade Compliance & Precise Fitment

   This A21-1602020 Clutch Master Cylinder is fully engineered to match OE specifications, ensuring seamless compatibility with target clutch systems. We conduct 100% dimensional calibration during production, with a tolerance control of ±0.02mm—far stricter than industry averages. Real-world tests show a 99.8% direct-fit rate, eliminating the need for modification during installation and reducing labor time for mechanics.

2. High-Strength Materials for Longevity

   The cylinder housing is made of high-density cast iron (HT250 grade) with a surface anti-corrosion coating, while the internal seals use imported fluororubber (FKM). These materials undergo 480-hour salt spray testing without rust or degradation, and the overall service life exceeds 60,000 operating kilometers—30% longer than standard aftermarket clutch master cylinders. This durability directly reduces end-users’ replacement frequency and costs.

3. Stable Hydraulic Performance & Leak-Proof Design

   As a core hydraulic clutch component, it maintains a working pressure range of 0-12MPa with a pressure fluctuation of ≤0.5MPa, ensuring smooth clutch engagement/disengagement even under extreme conditions. Every unit passes a 100% factory pressure test (holding 8MPa for 5 minutes) with zero leakage. Post-sales data shows a leak rate of less than 0.05% within the first 24 months of use, a key advantage over cheaper alternatives.

4. ISO-Certified Quality & Strict Quality Control

   Our production process is certified by both ISO 9001 and IATF 16949 (automotive quality standards), with 8 key inspection points from raw material incoming to finished product delivery. We implement a 20% random sampling test for each production batch, focusing on pressure resistance, material strength, and seal tightness. The cumulative defect rate has remained below 0.1% for 3 consecutive years, demonstrating reliable quality consistency.

5. User-Centric After-Sales Support

   Beyond product performance, we offer an 18-month warranty for the A21-1602020 Clutch Master Cylinder—6 months longer than the industry standard. Our technical support team provides 24-hour response to installation or performance inquiries, and we maintain a 98% problem-solving rate within 3 working days. This after-sales guarantee builds trust with distributors and end-users alike.

Technical Parameters

Product Uses

Here are specific application scenarios of Clutch Master Cylinder:

1. Daily Commuter Vehicles

   Ideal for vehicles used in daily urban/rural commuting, where clutch systems face frequent start-stop cycles. With a pressure fluctuation of ≤0.5MPa, it ensures smooth engagement even during 30+ daily start-stops, avoiding jolts. Its 60,000km design life aligns with the average annual mileage (15,000-20,000km) of commuter cars, reducing replacement frequency.

2. Light-Duty Commercial Vehicles

   Suitable for commercial vehicles (e.g., small trucks, delivery vans) that carry moderate loads. The HT250 cast iron housing resists deformation under repeated clutch pressure from load-bearing use. Its 12MPa maximum working pressure handles the extra force from loaded starts, maintaining stable performance for 40,000+ km of commercial operation.

3. Extreme Climate Conditions

   Performs reliably in harsh climates, from -40℃ cold regions (e.g., high-latitude areas) to 120℃ high-temperature zones (e.g., deserts). The FKM seals remain elastic in extreme temps, preventing oil leakage—tested to maintain seal integrity after 1,000 hours of alternating hot/cold cycles, ensuring no clutch failure due to weather.

4. Aftermarket Repair & Maintenance

   A top choice for auto repair shops and aftermarket replacement. With 99.8% OE-spec fitment, it eliminates modification needs, cutting installation time by 30% (from 1.5 hours to 1 hour on average). Backed by an 18-month warranty, it gives repairers and vehicle owners confidence in long-term performance, reducing post-repair complaints.

5. Fleet Operations

   Perfect for corporate or logistics fleets that require consistent, low-maintenance parts. Fleet data shows a 40% lower failure rate compared to generic clutch master cylinders, reducing downtime. Its compatibility with standard hydraulic fluids (DOT 3/DOT 4) also simplifies fleet maintenance, avoiding fluid-specific sourcing issues.
