This is not exact replica, but fit.
This is not exact replica, as hex 13/16" rather than 11/16". (wasn't exact fit for 13/16" deep well socket) Threads fit into unit, but need to add teflon tape.

Works exactly as described
Bought this item to repair a Pentair Mastertemp 400HD. Tried to use our pool heater for the first time this season and was met with disappointment. When our Easytouch called for heat, the heaters would light up, with the "service heater" light on. Heater would not attempt to light and blower motor dis not activate. I removed the top panel to read the service codes on the back of the main board and the HLS high limit sensor led light was lit. Ordered a more expensive sensor from another vendor on Amazon, because it said it was OEM. Turned out it was falsely advertised and was a non oem replacement like the one sold in this add. I returned, then purchased this non oem replacement and could not be happier. Cheaper price and it functions just like advertised.

Didn't work - Sensor tripped at too low a temp
Bought this to replace a broken sensor. After replacement, the heater would shut off when the water output temp was about 115 degrees. It should be 135, so the heater would just cycle on and off. Verified faulty operation by jumping the HLS wires together so the heater wouldn't shut down and using a temp probe to monitor water temp and a multimeter to monitor the HLS state.Replaced again with the OEM part and it worked perfectly. Would not recommend.
