Copper washer for oxygen sensor M18

Copper washer for oxygen sensor M18: precise sealing for performance exhausts

The Copper washer for oxygen sensor M18 ensures a perfect seal between the O₂ sensor and the exhaust thread. Designed for high-performance applications, it prevents leaks and keeps ECU readings accurate, helping maintain the correct air-fuel ratio for maximum power and efficiency.

How it works in the exhaust system

The oxygen sensor measures the O₂ levels in the exhaust gases so the ECU can adjust the air/fuel mixture. A poor seal can cause incorrect readings, engine faults, or power loss. The copper washer M18 prevents leaks, ensuring stable and precise sensor performance even under extreme conditions.

Technical advantages of this washer

• Perfect sealing: Copper compresses precisely to ensure a secure, leak-free connection.
• High heat resistance: Handles extreme exhaust temperatures without deformation.
• Corrosion protection: Maintains effectiveness even under harsh conditions.
• Full compatibility: Designed for standard M18 x 1.5 oxygen sensors.

Installation recommendations

• Ensure the mating surfaces are clean and free from dirt or debris.
• Install the washer between the oxygen sensor and the exhaust thread for a secure seal.
• Avoid over-tightening to prevent damage to the washer or sensor.
• Always replace the washer when reinstalling a used sensor for best results.
