331/39047 Dipper Arm Cylinder Seal Kit for JCB Equipment
Eliminate hydraulic fluid leaks and restore the powerful pulling and digging capabilities of your heavy equipment with the WINSCHEN premium 331/39047 Dipper Arm Cylinder Seal Kit. Engineered to withstand the extreme operational pressures, heavy payloads, and rugged environments of earthmoving and construction, this high-quality aftermarket repair kit ensures your JCB excavator operates safely and efficiently with zero pressure loss.
Key Features
- Manufactured to strict OEM dimensions for a 130mm bore x 95mm rod configuration, ensuring a precise and seamless fit for the dipper (arm) hydraulic cylinders used in JCB JS200, JS210, and JS220 series excavators.
- Constructed from advanced elastomeric, polyurethane, and heavy-duty wear-resistant materials to provide exceptional resistance to high hydraulic pressure, continuous rod friction, and extreme thermal variations.
- Effectively eliminates internal fluid bypass and external leakage, preventing dipper arm drift and maintaining highly responsive, consistent mechanical force during tough digging operations.
- This comprehensive seal kit includes all essential precision components—such as U-rings, wiper seals, O-rings, backup rings, piston seals, buffer rings, slide rings, and cushion rings—required for a complete and reliable cylinder overhaul.
- A cost-effective, highly reliable aftermarket alternative that meets or exceeds original equipment standards, minimizing your machine’s routine maintenance downtime.
