I found this one on desertcart and sure enough the 18 x 1.5 was the correct match. I strong armed the sensor out and the threads were in bad shape. All the threads from the sensor were gone and much of the material was in the the threads of the exhaust manifold. I used a deep impact socket and a breaker bar. The o-ring proved very worthy here as it slid up in the socket and held its place without falling out. Even being pushed all the way in the socket, it left plenty of the chaser tool exposed. I began turning and applying pressure to get it threading into the exhaust manifold. Since this isn't a tap for true thread cutting, it would get tight and hard to turn. The name of the game here is tighten it and back it off, back and forth, around an 1/8 to 1/4 turn at a time. This is why I used the breaker bar, a ratchet would continually have to have the direction switched to go back and forth which is a pain. As you keep threading it in further and doing the back and forth, you can feel it loosening as it clears threads. Every time you back it off, you try to slightly advance the turn, until you get all the way through. I sprayed a little WD40 occasionally to help with the friction as it will get warm to hot. In conclusion this thread chaser worked perfectly and ultimately saved the day! Lisle tools have always been a quality go to for me. The thought of replacing the exhaust manifold and the headaches that one can encounter doing that job, were happily avoided. I helped my son do this job. The value of patience and making sure you have the right tools to do the job, really shined through here! BTW: I used a standard o2 sensor socket to start with. After about 1 full turn it got real tight, where then the socket splayed and jumped, which suggested the threads were galling. Ultimately I had to clip the wires on the sensor and remove the upper parts of it to get a regular deep well socket on to get it out. An o2 sensor socket is longer than a standard deep well socket. Hopefully this may prove helpful to someone else with the same problem Review: Belongs in every mechanic's toolbox - Every once in a while I run into a spark plug or oxygen sensor that fights me on the way out. I've run into enough galled threads that I scrupulously use anti-seize compound on both, but anti-seize won't help you if the threads are damaged or full of trash-- or if the last guy forgot to use it. I've found that if I'm careful removing things, I can usually clean up the threads with a thread chaser and they'll be fine. I don't like using a tap if I can avoid it because taps tend to remove more material, and I want to preserve as much of the metal as I can. Most times a thread chaser is enough to get things back on track. I've used Lisle tools for years. They are usually a good balance point between quality and price. This chaser is no exception. I use this whenever I replace an oxygen sensor and sometimes when I replace spark plugs. The $7 that it costs is NOTHING compared to the headaches that it will solve if you accidentally damage or cross-thread something. If you do your own maintenance work, you should have one. ## Features - Spark Plug Hole Thread Chaser ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0009OMYCO | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #127,692 in Automotive ( See Top 100 in Automotive ) #233 in Spark Plug & Ignition Tools | | Brand Name | Lisle | | Compatible with Vehicle Type | UTV | | Core Material | Alloy Steel | | Customer Reviews | 4.6 4.6 out of 5 stars (991) | | Global Trade Identification Number | 00083045202004 | | Included Components | Item | | Item Type Name | Tools | | Item Weight | 0.2 Pounds | | Manufacturer | Lisle | | Manufacturer Part Number | 20200 | | Manufacturer Warranty Description | Lifetime warranty does not cover abuse | | Model Number | 20200 | | OEM Equivalent Part Number | 20200 | | Thread Size | 14mm, 18mm | | Top Material Type | Alloy Steel | | UPC | 083045202004 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Lisle - **Core Material:** Alloy Steel - **Thread Size:** 14mm, 18mm - **Top Material Type:** Alloy Steel - **Vehicle Service Type:** UTV ## Images ![20200 Thread Chaser - Image 1](https://m.media-amazon.com/images/I/41RVcfCM5DL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saved the day! *by G***T on January 20, 2020* I was replacing the o2 sensor on a bmw 3.0 and I could tell the threads were galling and if I were to finish removing the sensor, I may not be able to get the new one back in.

Unit seems to be high quality and held up well during my usage. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/2541501-20200-thread-chaser](https://www.desertcart.nz/products/2541501-20200-thread-chaser) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-04-24*
