Finding the right maintenance parts for your fleet is critical for reducing downtime. Whether you are searching for the 08088-30000 (0808830000) battery relay or the 07050-41200 (0705041200) diesel tank filler cap, we provide OEM-standard replacements designed for Komatsu PC200, PC300, and PC400 series excavators. These parts ensure your machine electrical system and fuel system remain secure under harsh working conditions.
Our heavy-duty components are built to match the original factory performance. Below is the detailed data for your procurement reference:
| Detail Item | Battery Relay / Switch | Fuel Tank Filler Cap |
|---|---|---|

Comparing our products with standard aftermarket options highlights why fleet managers trust our supply chain:
| Feature | Standard Aftermarket | Our OEM-Standard Replacement |
|---|---|---|
| Material Quality | Recycled copper / Thin plastic | High-purity copper contacts / Reinforced steel |
| Sealing Performance | Prone to moisture entry | IP67 Rated Waterproof (Rubber Block Protection) |
| Service Life | 6-12 Months | Extended 24-Month Durability |
| Fitment Precision | Tight or loose fit issues | 1:1 Precise engineering to Komatsu specs |
| Fuel Protection | Simple lock mechanism | Anti-leak and anti-theft locking design |
| Electrical Stability | Voltage drops frequent | Stable 24V conductivity for heavy cranking |
The 08088-30000 battery switch is often the culprit. Over time, internal contacts corrode. Replacing it with a high-conductivity relay restores the circuit integrity immediately. Check if the rubber block is intact to prevent future moisture damage.
A damaged 07050-41200 fuel cap affects the tank's ventilation. Our replacement caps feature a specialized breathing valve to ensure constant fuel flow to the engine without allowing dirt or water to enter the diesel supply.
Answer: Our parts utilize an OEM-standard tri-metal structure for electrical components and high-grade sealing polymers for tank caps. We are trusted by repair shops and equipment fleets globally for consistent quality and fast dispatch.
