WORKED LIKE A CHARM!!
I have a Bradford White model URG275H6N, not a Reliance brand, but it was the closest unit to my existing thermocouple that had the crimped connectors for the overtemp switch. My pilot assembly had a nut that fit around the thermocouple and screwed into a bracket. I had to cut that nut off, gently open the cut to fit the new wires into it and screwed it back it. The wire lengths were just enough and upon install, my water heater fired right up. My original problem was that the pilot light went out and wouldn't turn back on. You Tube suggested the faulty TC and was right. Saved me a minimum $300 serv call for less than $20 bucks! I'm a Happy Camper!

perfect exact replacement
THANK YOU, THANK YOU!!!! First hot shower in a week! I couldn't buy the part locally and refused to pay a plumber 200 to 300 dollars to replace it. Took about an hour but that was no fault of the part, the retaining screw was frozen in place. I finally took it out to the garage, clamped it in the vice, put a drop of PB blaster on the top and bottom, heated it with a small butane torch and it came right out. The whole thing might have been easier if I had unfolded the directions... but I guess that just isn't my style! Any how, I feel better and smell better now!

Easy fix for Envirotemp water heater.
At least one other reviewer mentioned this working for their old, discontinued Envirotemp water heater. I ordered this based on their positive review. They were right. Most generic thermopiles available at home improvement stores aren't a good fit. This one is. Got an Envirotemp? This is likely the part you're looking for. It's an easy fix for the light to moderately handy. Saved me the cost of a new water heater. That's a win.

Faulty Item
I bought this item with the hopes that I would be able to fix my hot water heater at home. I looked up what I needed and ordered what I thought was a new item. I replaced my old thermopile with the new one and my water heater still would not work. It wasn’t until later when I had no choice but to hire a professional that I was told the thermopile I ordered was used or faulty. When I went on my account to try and return the item, my window was “closed”. I’m not going to lie, I am really upset about all of this. I have never had a bad experience with an Amazon product before so this really sucked.
