Hot Sales EX60-5 EX70-5 Boom Arm Bucket Hydraulic Cylinder Seal Kit

Product Description

The Hot Sales EX60-5 EX70-5 Boom Arm Bucket Hydraulic Cylinder Seal Kit is used to seal up the gap between different parts of the hydraulic cylinder. They can be used under high pressure and also can be used between the head and the connecting rod when the rod and cylinder seal are reciproing. We usually call them as BOOM / ARM / BUCKET cylinder seal kit.

Key Features

· High Efficiency: Optimizes hydraulic system performance by minimizing friction and energy loss.
· Heat Resistant: Withstands extreme temperatures (-30°C to +120°C) without compromising integrity.
· Excellent Elasticity: Adapts dynamically to cylinder movements, maintaining a perfect seal under varying pressures.
· Superior Sealing Performance: Prevents fluid leaks and contaminants, ensuring smooth cylinder operation.
· Oil Resistance: Compatible with hydraulic oils, lubricants, and other fluids, resisting degradation and swelling.
· Long Service Life: Crafted from high-quality materials to endure abrasive environments and heavy-duty cycles.

Applications

· Excavator Models: Compatible with EX60-5 and EX70-5 series.
