Filler Cap
The Filler Cap is a precision-molded sealing component designed to securely close the engine oil filling port while preventing contamination and maintaining proper internal pressure. It ensures a leak-free seal, protects the lubrication system, and supports safe oil servicing operations in heavy commercial vehicles.
Built from high-strength, heat-resistant composite material, the filler cap withstands engine temperatures, oil exposure, and vibration. Its integrated sealing ring provides consistent compression to prevent oil vapors and liquid from escaping. The ergonomic grip design ensures easy installation and removal during maintenance.
A reliable filler cap is essential for maintaining clean engine operation, preventing dust and moisture entry, and ensuring long-term lubrication system stability.
