Features:

  • Heavy Duty, solid cast steel construction, made to increase torque on hard-to-remove O2 sensors and help you access tough spots easily
  • Universal fit: 7/8 inch (22 millimeter) hex fits almost all oxygen sensors, 1/2" drive for ratchets.
  • Low profile: standard 6 point with low profile and slotted design to enable removal of 02 sensors while keeping the harness attached.
  • Precision casting for strength and accurate fit
  • Perfect companion for oxygen sensor
Perfect...

Worked perfectly to remove upstream O2 sensor.

Works great!

Reasonably priced and worked extremely well for removing several 20 year old O2 sensors. Seems quite well made with quality metal. No damage after its challenging first job.

Five Stars

Best tool to replace an O2 sensor.

Works well.

Works... Easily took the O2 sensor out. I guess it would've been different if it was seized but nope. Not sure how long it will last but for the DIY people who only need it a few times.... It's perfect. TSB on my 2004 Mazda 3 advises to use CRC Freeze Off for seized sensors. It's like PB Blaster but it freezes the metal. Be careful with it.

Absolutely perfect for one of two O2 sensors

I have a Subaru, and it really is a 22mm socket. It fits the hexnut exactly. I hammered every day with a monster crescent wrench for a week without making any progress. I used this socket with a pipe over the ratchet wrench handle, applied pressure very slowly, and the O2 sensor came out easily. I did use a $2 pipe clamp around the socket to make sure it wouldn't expand and "skip". I also used PB-Blaster every day. However, I have two O2 sensors. The second O2 sensor was too fat to fit into this socket. Since the connector itself fits through the 22mm opening, I just ordered a 6pt boxend wrench to take care of it. This socket is very heavy and feels like it's not likely to expand under stress, but the pipe clamp made sure of that (I got the idea from another post). If you want those O2 sensors intact, don't mess around with adjustable wrenches or a 2pt open-ended wrench ... you'll just damage the nuthead. It takes so much force to break it loose, I'm even wary of a 12pt wrench (if you can get it over the connector). Get the right tool and save time. If you use some variant of this cutout socket (like a wrench), be sure you can use something like a pipe clamp to keep it from expanding & skipping.

I highly recommend.

I was told that these open slot sockets will open up under the pressure of taking out the O2 Sensor, but from the reviews I decided to give it a shot. This thing is really heavy duty, and even under the heavy pressure that had to be applied, it didn't open one bit and did the job. I highly recommend.

)2 sensor socket.

The offset feature worked great for mt application

Good quality short O2 sensor socket

Good quality short O2 sensor socket. The drive hole is 1/2 which is much better than a 3/8 drive hole.

Saves You Alot of Time!

This socket saved the day! To get to the oxygen sensor between the firewall and the engine, it is recommended to lower the front of the engine three inches. By using this socket I didnt have to go through all that trouble. Great little tool! Would be nice if it could be thin wall. Very limited space but, it still worked. Very satisfied!
