The cheap eBay senders are made of very thin brass, and will shear off very easily if you over-torque them - and it doesn't take a great deal of effort to do so, so be careful. We had a slight drip from using the bare adapter and temperature sender, which was fixed with the application of a small amount of teflon tape.

You can find this particular adapter on eBay - (seller link) or general eBay search. Just be careful with the general eBay search and make sure that it's the correct size.
