Hi Tommy and thank you for your question. for information about products that would fit a Craftmaster, you would need to contact them.
Thank you for asking, Darrel. Please contact the manufactued to make sure this is compatible. Thank you and have a great day.
Hello Mike S, thanks for reaching out. This is due to a protective coating added to the end of the elements to prevent lime-scale build up on the elements and prevent them from oxidizing to the element heating up. As metals are heated stainless alloys or not the oxidize more quickly under extreme heat.
Hello Homeuser, Thanks for reaching out. Because it is the correct wattage and voltage for the unit, it should fit. You would also want to make sure that the element is not too long to fit inside the heater.
Thank you for asking. The Wire Terminals are stainless.
Unfortnately, I am not sure what water heater you have so I am unable to tell you if this element would work for you. Make sure the element has the correct voltage and wattage for your unit and the length is correct.
Unfortunately, Without the model or serial number for the unit in question it would be hard to say. 20 gallon units tend to be on threshold of being capable of having 240v capabilities as well as 120v capabilities. I have also seen them with wattage elements up to 4500. So Into the blind so to speak I'm going to say that element is likely undersized. However, without the model or serial number its hard to say for certain.
Earl, two things are suspect, breakers go bad or there is a short in your wiring. An electrician would verify the voltage to your element and that the circuit is 120 volts. When I replaced my element I also checked my junction box and was surprised to find the screw on wire splices were bad. I had to run new wires. It’s one thing to replace the element, tracking down a short may take a professional electrician.
This uses 1-9/32" NPT thread size. The nominal size is 1".
The element is stainless steel, the the threaded nut is plated steel.
