Hella 7.00018.55.0 Secondary Air Injection Control Valve FKM/FPM

The Hella 7.00018.55.0 is a secondary air injection control valve engineered to OEM specifications, featuring FKM/FPM (fluoroelastomer) seals for superior heat and chemical resistance. This valve plays a critical role in the vehicle's emissions control system, regulating airflow into the exhaust stream during cold-start conditions to reduce hydrocarbon and carbon monoxide output.

During a cold start, the secondary air injection system pumps fresh air directly into the exhaust to help unburned fuel combust and accelerate catalytic converter warm-up. The control valve opens to allow this airflow and closes to prevent hot exhaust gases from flowing backward and damaging the air pump. A failed or stuck valve can trigger a check engine light and cause the vehicle to fail emissions testing.

Key Features:

• OEM-equivalent quality from Hella, a direct supplier to major European automakers
• FKM/FPM fluoroelastomer seals for enhanced durability against heat and chemical exposure
• Right-side fitting position for precise OEM replacement
• Compliant with Euro 5 and Euro 6 emission standards
• Also known as a combi valve or secondary air check valve
• Manufactured to meet or exceed original factory specifications

This valve is a direct-fit OEM-quality replacement designed to restore proper secondary air injection system function and ensure emissions compliance. Cross-reference part numbers include 7PP131109, 678161P, and WG1946721.
