The Heli-Coil R514-11 is a precision-engineered thread repair insert specifically designed for 18mm x 1.5 oxygen sensor applications. This heavy-duty insert provides a permanent solution for damaged, worn, or cross-threaded oxygen sensor ports in exhaust manifolds, catalytic converters, and exhaust pipes.

Key Features:

• 18mm x 1.5 metric thread size for oxygen sensor applications
• Manufactured from high-quality stainless steel for corrosion resistance
• Withstands extreme exhaust temperatures and vibration
• Creates stronger threads than the original tapped hole
• Permanent repair solution that eliminates the need for costly part replacement
• Compatible with standard Heli-Coil installation tools

Heli-Coil thread inserts are the industry standard for professional thread repair. The coiled wire design distributes stress evenly across all engaged threads, creating a durable connection that actually exceeds the strength of the original threads. This insert is essential for repairing stripped oxygen sensor bungs on exhaust systems, restoring proper thread engagement and preventing exhaust leaks.

Installation Note: Requires appropriate Heli-Coil tap and installation tool for proper installation. The insert installs into a precisely tapped hole and provides a perfect 18mm x 1.5 thread for oxygen sensor mounting.
