ZAX330 12-Screw Bucket Cylinder Seal Kit Description

The YNF17043 Bucket Cylinder Seal Kit, replacing 4640108, is designed for the Hitachi ZAX330 excavator specifically using the 12-screw bucket cylinder design. Compared with the 8-screw model, the 12-screw type operates under higher structural rigidity and sustained high-pressure cycles, making seal quality essential for maintaining full digging force and hydraulic control.

Constructed from premium PU, NBR, PTFE, and advanced composite materials, the seals provide exceptional resistance to pressure, abrasion, heat, and hydraulic contamination. The kit includes rod seals, piston seals, dust seals, wear rings, and O-rings to deliver a complete and reliable rebuild solution. Each component is precision-engineered for OEM-standard fitment and consistent performance in demanding working environments.

The YNF17043 kit is widely chosen by excavator repair centers, fleet owners, and aftermarket parts suppliers due to its stable quality, long lifespan, and cost-effective replacement value.
