Lisle 12230 Oxygen Sensor Thread Chaser , Black

Lisle makes great tools, and this oxygen sensor thread chaser is no exception. Excellent build quality, smooth operation, and it cleans up damaged threads perfectly. If you work with O2 sensors even from time to time, this tool is an absolute must-have. Saves a ton of headaches and keeps you from ruining bungs or manifolds. Reliable, well-made, and worth every penny. Highly recommended for any mechanic.

This worked perfectly for me. The small size makes it easy to fish into tight spaces, too.

Works great, fast shipping

Used this tool to clean threads in threaded hole for O2 sensor. It is hardened steel, tough, generally well made, and served the purpose but cutting teeth could be sharper.

Cannot recommend enough! Haven't ever dealt with a y pipe as dickered as the one I bought this for. The steel was pretty hard and I was afraid I'd have to bust out a proper tap to fix the threads, but I don't like using those to fix damaged threads on account of them removing too much material, so I figured I'd try this guy out, and I couldn't be happier! Used a little cutting wax and it tapped right in like a hot knife through butter! Worth its weight in gold! I'd pay 20 bucks more for it now that I know how fantastic it is!

High quality, very durable. It works as intended

Its a thread chaser, nothing special, but works perfectly . Its a should have item if you ever change out an O2 sensor since the threads do get rusty, and dirty from the exhaust. After using this your O2 sensor should go in nicely, at least mine do. Just remember, this is chaser, not a cutter. This will clean up the threads, fix minor issues, but it won't put new threads in.

Don't its job

Works exactly as it should. Re threaded two o2 bungs so far!

Debía corregir la rosca del sensor de oxígeno y con esta pequeña Pieza lo corregí fácilmente, el mecánico quería desmontar el mofle o escape y llevarla a un tornero, no fue necesario ya que con con esta herramienta 🔧 corregi yo solo el problema, muy recomendable y fácil de usar EXCELENTE me ahorre (tiempo dinero y esfuerzo)

Worked very well on my 1999 Harley Road King gas tank thread where the line goes into the tank. If you have an older Harley with the MM FI and need to clean up that thread, this is the tool you need.

Funcionando en un focus 2002, dejo limpia la rosca justo como esperaba!

Tool is not hard enough, threads were messed up from the first hole I cleaned... now I need a thread chaser for my thread chaser... cleaned up the hole nicely but I think when it is no longer usable, I will just make one out of an old O2 sensor using a dremel.
