1-1/4" SS nut for my kettle element??

[Seb]

Wasn't sure if I should post it in the Electric board...

Anyways, I bought an element at Canadian Tire that sort of looks like this :

My plan was to buy a 1-1/4" SS nut to weld on my kettle so I could screw/unscrew the element in case it breaks or to wash it.

Problem is... I can't find any nuts of this size anywhere! How'd you guys do it?

or you can solder in a welding spud for a real slick job!

These seem to be 1/2, 1/4 and 1".

I'd be looking for a 1-1/4 one.

It does seem to be what I'm looking for! Thanks a lot!

id be careful that is a hex nut, not a lock nut.

its thread is not a pipe thread

Are you sure the thread is 1-1/4" NPS on your element?

1" NPS, which is the standard water heater element size, is actually ~1-1/4" OD.

If it is actually 1-1/4" NPS, then the thread pitch on those ebay screw nuts is wrong.

In any case, this is a good source for what you're probably looking for:

Yikes, I don't understand a single thing of what you said hahaha! I'm horrible with stuff like that, I have absolutely no knowledge at all.

What'S NPS and OD?

I remember measuring the diameter of the element's base and it was 1-1/4" so I guess the diameter of the inside of the nut must be 1-1/4 as well right?

I know nothing about the electric stuff, but would this work?

OD is outer diameter. So the outer diameter of 1 inch pipe is roughly 1 1/4 inches. You need a 1 inch ss lock nut.

 

[aquenne]

measure the outside diameter of the threads of the element.

im pretty sure you've got a 1" NPS element, not 1.25" (these are not nominal values, 1" pipe thread does not actually measure 1"). Sorry to sound confusing, i say blame the brits.

Yes, that will work.

NPS is National Pipe Straight thread and OD means Outside Diameter.

The measured largest diameter of a 1" NPS male thread is between 1.281 and 1.293 inches. It's called a 1" pipe thread because the nominal inside diameter (ID) of the pipe is 1".
