Sumitomo SH350-5HD Boom Seal Kit Description
YNF17205 is a boom cylinder seal kit (LZ00477) specially designed for Sumitomo SH350-5HD excavators. The boom cylinder is essential for lifting and operating the excavator’s boom, and its seals must perform reliably under high hydraulic pressure. Over time, seals wear due to oil contamination, heat, and continuous operation, leading to hydraulic oil leakage and reduced performance. This aftermarket repair kit provides all the required seals and O-rings to fully restore the boom cylinder. Manufactured with advanced sealing compounds that resist oil, heat, and abrasion, the kit ensures long-lasting performance and minimizes downtime. YNF seal kits are widely adopted by repair shops, fleet owners, and parts distributors who require high-quality and affordable alternatives to OEM parts.
