In racing applications where high stresses and vibrations occur over long periods of time and lateral loads are applied to the plugs, welds attached to thin-walled titanium tubes will eventually fatigue and fail. The support bracket for the M18 size O2 sensor plug helps distribute the load applied to the plug over the larger surface area of the tube to help prevent weld fatigue over time. Take precautions with our titanium M18 O2 stent holder to ensure your O2 stent stays in place even in the harshest conditions.
