My iron plate fire went out. I searched for a long time and finally found this replacement. It is the right length and easy to install. It solves the problem perfectly. Worth recommending

Our hot water stopped comming out and I thought the pilot light just needed to be lit back up but the light would only stay lit if I kept the gas button pressed, and once I let go of it, the light would turn back off. I looked online and it said it might be the Thermocouple that needs replacing.I went and bought this for $10 and saw a YouTube video that showed how to replace it, I got to work on it, and then we had hot water again. I am BY NO MEANS a handy man AT ALL (it took me 40 minutes to replace my windshield wipers the first time I did it and it is something that literally takes one minute to do when you know what you are doing. This is how bad I am at fixing things 🤦‍♂️) and this took me less than 15 minutes to do. I'm glad I found this universal piece at such a low price. I bet I would have been charged $100+ if I had a tech come in and do it.

Did not work for my boiler. It did indeed keep the pilot lit, but would intermittently go out, driving me insane. Replacing with a higher quality thermocouple fixed the issue.

I have found that the thermocouple lasts for years but will fail at the most inopportune times. Have aa extra always on hand for my water heater and garage furnace . The universal thermo couple fits both of my appliances well and was easy to fit each application.

I purchased this item twice. The first time, it worked fine, no issues. The second time, it threaded poorly due to the boiler being old, when I tried to back it out, this item snapped in half. It literally crumbled inside the wrench.
