Smart Protection for Fuel Delivery & Management Systems

The fuel system is vital for delivering clean, reliable fuel to the engine in both ICE and hybrid vehicles. Key components like fuel lines, fuel pumps, injectors, and high-pressure rails require protection from contamination, moisture, and mechanical damage to ensure optimal performance, emission compliance, and durability throughout production and logistics.

Fuel & vapor system protection ensures clean, compliant flow from tank to injector in ICE and hybrid NEVs.

Contamination Control in Fuel Systems – Cleanroom-Compliant
Tailored protective solutions safeguard fuel lines, injectors, tank modules, and fittings from dirt, dust, and moisture during production, assembly, and logistics. Fully cleanroom-ready and VDA 19 compliant, they ensure uninterrupted fuel flow and protect injectors, where even the smallest particle can block performance. Soft sealing materials provide a secure fit and add an extra layer of protection against contamination ingress.

Emission System Safeguards
Engineered to safeguard Evaporative Emission Control (EVAP) components such as purge valves, vent lines, and charcoal canisters, ensuring compliance and preventing vapor leaks.

Hybrid System Readiness
For hybrid platforms with irregular engine cycling, our solutions support clean, stable fuel delivery and consistent pressure across all driving modes.

High-Pressure Fuel Zone Protection
Designed to
shield critical components such as common rails, pressure sensors, and injectors from contamination and mechanical damage in high-pressure zones.
