The Snap-on 3/8" Drive M22 x 1.5 Thread Chaser, No. S6207, is designed to repair threads that are often damaged when replacing heavy duty diesel DPF (diesel particulate filter) system sensors. Under-vehicle sensors can rust or seize in place and removing them often results in the costly need to replace DPF components. The S6207 rethreads damaged parts and saves technicians time. Its design services any sensor bung that has an M22 x 1.5 thread size and can be used with a 3/8" ratchet or 7/8" wrench or socket.
