Worth knowing. “Sensor safe” matters more than it sounds. An ordinary acetoxy silicone gives off acetic acid as it cures, which attacks oxygen sensors — on a modern engine use a sensor-safe RTV or you may cure a leak and buy a sensor. On this shelf the 66C general-purpose clear adhesive sealant is the one that is not sold as sensor safe, and it is the one the warning is about.

Taken from the product’s own name, converted where the unit differs, and from the standard where the range cites one. Tell us the application and we will confirm the exact item before you order.
