A: The seal repair kit is not included in standard products. You can purchase the dedicated matching kit separately, and we will offer a favorable price for combined orders.
Q3: What packaging is used for long-distance sea transportation?
A: Anti-rust oil is injected into the cylinder interior, and anti-rust grease is coated on the piston rod. The whole product is wrapped with waterproof PE film and packed in sturdy export plywood cases.
Q4: Will there be discount benefits when purchasing a full set of working device cylinders?
A: Yes. Orders for complete cylinder sets enjoy tiered discounts. We also provide consolidated shipment service to help you save logistics costs.
Q5: What support can you provide if oil leakage occurs within the warranty period?
A: Please take clear photos of the leakage area and provide the excavator serial number. We will arrange free seal replacement and professional remote technical guidance in a timely manner.
