Great product! Was easy to install and worked perfectly with my water heater. It restored functionality right away, and the quality feels solid. Shipping was fast, and the price was very reasonable. Highly recommend for anyone needing a quick replacement!"

Arrived fairly quickly and was exactly the same as original part, I installed in less than an hour and it's working perfectly. Saved the need to replace the water heater. Very happy.

Installed this assembly on an AO Smith XCV 50 100 water heater to resolve thermo coupler issue causing NO HOT WATER. This part fit perfectly other than tubing being a little longer than the original part. I was able to gently bend the tubing careful not to kink it when installing. Turned on pilot light with igniter and after moving control switch to ON the burner ignited and 20 minutes later HOT water. Some comments say part only lasted a few weeks, only just installed part but I will update if/when issues are encountered.

I ended buying 2 back to back accepting I may have just got a bad one and I can deal with the return process later knowing I can buy another and get it quick. Welp, the first one, the aluminum gas tube broke off as soon as the burner lit. The second one, both the gas tube and igniter wire caught fire a minute after the burn was lit. The wires were low enough and not in the way of the flame so I’m questioning the quality of this product. I’m no professional, but am knowledgeable enough to know how some things work and I’ve installed a few of these that have lasted years. Beware of the this products quality.

AO Smith FCV-40-100 38 gal water heater. Pilot light kept going out after some period of time. Checked the thermocouple, & tried cleaning the pilot gas tube, but no luck. This part fit, and works. No problems since. Pretty easy to install with a couple of wrenches. Yay.
