This twin pack of Ticon titanium O2 sensor bungs fits 2.75in to 5in tubing and uses M18x1.5 threads with coped ends for welding into tube walls. Supplied as a pair, these weld-in sensor bungs let fabricators add dual O2 monitoring points or keep a spare for exhaust builds, simplifying sensor installation while matching tubing contours for solid welds.
