All the pipeline joints are argon arc welded by international brand automatic welding production line, single-side welding but
double-side finished. The welding machine can check the welding quality at the same time when it welds. The advanced welding
machine can ensure that the finished pipeline will never leak oil.
Precision-Engineered Hydraulic Breaker Piping Kits specifically designed for Komatsu PC350LC-8 excavators. As a heavy-duty 35-ton class machine, the PC350 requires a robust auxiliary hydraulic system capable of sustaining constant high-pressure cycles. Our pipelines are built to match the original Komatsu factory specifications, ensuring a zero-leakage, 100% plug-and-play installation.

Independent Oil Return Design: For 35-ton class carriers like the PC350LC-8, we strictly implement an Independent Oil Return Line. This bypasses the multi-way valve and returns directly to the hydraulic tank, significantly reducing back pressure and protecting your breaker’s piston and seals from overheating.
CNC Cold Bending: Every hard pipe is bent using high-precision CNC cold-forming technology to perfectly contour with the PC350’s boom and arm, preventing interference with other hydraulic lines.
Reinforced Clamping System: Includes heavy-duty galvanized steel clamps with shock-absorbing rubber inserts to handle the high vibration of heavy mining work.
