Can someone identify this connector and suggest a source?

I'm repairing a steam heater that had a thermal fuse and need to reconnect the new one but I can't use solder since the heat would melt it. The original had these crimp connectors but I don't know what they are called or where to get them. Can someone give me a clue? Thanks.

Use flexible copper tube as a crimp?

Would wire nuts be an option?

They're often listed as "ferrules" but you can often snip off the barrel of a crimp-on connector or butt-splice and use that.

Hi Franklin;

Actually you can solder these.
1. You have to do it very quickly on only 1 lead at a time and as far from the body as possible.
2. It's helpful to use a heat absorbing plier between the body and the place you are soldering.
3. It's helpful to have the body dipped in cold water.

Tin the wire first and leave a gob of solder on it.
Do this as quickly as possible. An extra pair of hands is very helpful.

Something similar is called a "ground wire crimp connector" and is found in the electrical department of a home improvement store...

It is used like this...

P.S. Also they sell all sorts of smaller crimp connectors in an auto parts store (if low voltage which those are rated for).

Or search google.com for the words...

butt splice connector

...then click on images.

Have you tried McMaster Carr. This looks almost like what you have.

Ok guys, the leads on those thermal fuses is about 0.025" or so.

I suspect that you can buy whatever you want at a local appliance repair parts supplier. A lot of stoves and hot water heaters use special wire with extreme high temperature insulation and cannot use solder for connections.

The trick is to get a counter person to look at what you are trying to do and give you some support. Often they just want you to provide a make, model, and catalog number.

IF you get your replacement therm fuses from NTE I Know they come with the ferrules In the bag....

My Mr Coffee thanks me for fixing him.

A standard crimp connector used on screw terminals works just fine for that. Just cut off the the part that normally goes under the screw or nut.

Can someone identify this connector and suggest a source?
