Furukawa HB30G Hydraulic Breaker Seal Kit OEM-Grade PU Piston Seal

🌟 Product Features

• Imported PU Material: High-performance polyurethane with excellent wear resistance, high-pressure tolerance, and anti-aging properties, outperforming standard rubber seals in harsh working conditions.
• OEM-Exact Dimensions: All seals match original Furukawa HB30G specifications, ensuring perfect fit without modifications or adjustments.
• Complete Kit Coverage: Includes all seals required for full cylinder rebuild, eliminating the need to source individual components separately.
• High-Pressure Resistance: Withstands operating pressures up to 125 MPa, maintaining stable sealing performance under heavy impact loads.
• Wide Temperature Adaptability: Works reliably in environments from -35℃ to +135℃, suitable for both cold and hot climate operations.
• Precision Molded: CNC-machined molds ensure consistent dimensions and smooth surface finish, reducing friction and wear during operation.
• Anti-Contamination Design: Dust wipers effectively block rock dust and debris from entering the cylinder, extending the lifespan of internal components.

🔍 Technology & Principle

1. Main Piston Seal: The U-cup polyurethane seal creates a tight barrier between the piston and cylinder wall, preventing hydraulic oil leakage and maintaining system pressure for consistent impact force.
2. Buffer Seal: Absorbs pressure spikes during piston impact, protecting the main seal from damage and extending its service life.
3. O-Rings: Provide static sealing at connection points between the cylinder body, front head, and rear cover, preventing oil seepage.
4. Dust Wiper: Scrapes rock dust, mud, and debris off the chisel shank before it enters the cylinder, preventing abrasive wear on the piston and bushings.
5. Guide Rings: Keep the piston centered within the cylinder, reducing metal-to-metal contact and ensuring smooth reciprocating motion.

🚀 Advantages

1. 40% Longer Service Life: Imported PU material resists abrasion and pressure spikes better than standard rubber seals, extending replacement intervals to 800-1200 working hours.
2. Zero Leakage Performance: Precision-molded seals maintain tight fit even after repeated impact cycles, eliminating oil leaks that reduce breaker efficiency.
3. Cost-Effective Maintenance: Complete kit includes all required seals, reducing total maintenance cost by 30% compared to sourcing individual components.
4. Easy Installation: Seals are designed for straightforward installation with basic hand tools, requiring no special equipment or skills.
5. Perfect Compatibility: 100% matches original Furukawa HB30G dimensions, ensuring seamless integration with existing cylinder components.
6. Global Availability: In-stock kits ship within 3-5 business days, minimizing equipment downtime.
