4454095 Original Excavator Rubber Parts for ZX200-3G

The original rubber parts (part number 4454095) are genuine factory accessories for the Hitachi ZX200-3G excavator, mainly used for sealing, shock absorption or connection parts of this model. The ZX200-3G is a Hitachi Construction Machinery 20 ton medium-sized excavator, equipped with an Isuzu AA-6BG1T direct injection diesel engine as standard, with a total working mass of approximately 19.8 tons. The universal number 4454095 of this rubber component is its unique identifier in Hitachi's original accessory system, ensuring a complete match with the host structure. When placing an order, it is necessary to provide the complete model and engine number of the excavator for verification to avoid mismatches.

This product is a commonly used functional rubber product in construction machinery, which may include oil seals, O-rings, gaskets, shock-absorbing rubber strips, water pipes or oil pipes, etc. The material is usually nitrile rubber (NBR), ethylene propylene diene monomer (EPDM) or silicone rubber, which has excellent oil resistance, high temperature resistance (about ‑ 40 ° C to+150 ° C), ozone resistance and aging resistance. Its design needs to meet the long-term reliable sealing or buffering requirements of excavators in vibration, impact, oil immersion, and dusty environments. For example, oil seals can prevent oil and hydraulic oil leakage; Shock absorbing rubber strips are used to absorb vibrations from components such as fans and engines; Water/oil pipes need to withstand system pressure and maintain flexibility.

It is recommended to check the rubber parts for signs of hardening, cracking, deformation, wear, or leakage every 500 hours of work or every quarter. When replacing, thoroughly clean the installation contact surface, remove old adhesive residue, and use original 4454095 pieces and matching sealant (if necessary). During installation, tighten according to the torque and sequence specified in the maintenance manual to avoid early failure caused by excessive stretching or compression. Rubber parts should be kept clean on a daily basis, avoiding contact with sharp tools, strong solvents, and long-term direct sunlight. When storing, it should be placed in a cool and dry place, away from oil stains and heavy pressure. Regular maintenance can effectively prevent oil leakage, abnormal noise, and component wear, ensuring stable operation of equipment.
