Primarily designed to be connected directly to MaxxECU, but obviously work with other systems as well.
4.7 mm thickness of the sensor.
Reaciton time: 1250ms
-100 to 1300 degress Celscius (-148 to 2375 F)
Covered sensor tip. May be needed with ALS and some race E85 fuels.
 
For tapered thread compression fitting to the stainless steel bung: about 2.5 turns to finger tight, then 3/4 of a wrench turn.
For tapered thread compression fitting to the mild steel bung: about 3.25 turn to finger tight, then 1 wrench turn.

What is important is that the threads do not leak. If the fitting is overtightened with a wrench the fitting will be impossible to remove. It is important that the fitting is not overtightened.
