I had a faucet develop a leak through a poor casting recently. I ordered the replacement faucet (bridge style) and it turned out to have deck nipples that were too short to penetrate the 1.5″ concrete countertop to which it should mount. I was able to track down the Danze deck extension kit that should get me out of my pickle. The extension is essentially a brass female threaded piece that becomes the lockring that sandwiches the counter between it and the faucet. The brass piece continues down from there with nipples to attach the supply lines.
I am concerned as to how to properly seal the threads between the faucet and the extension. They are not tapered as they are designed to allow for a variety of oversized countertops. Should I just teflon tape the entire faucet stem and hope to get enough compression in the threads to create a seal? Is there a better option? Dope? Both? The threads seem loose but, I think, that comes from the non-tapered nature of them.
It seems like a simple thing

The standard for wraps of Teflon tape is three but I've done less and more. If they are loose you could try four or five wraps on both sides while it is still up on a work surface. Install one side most of the way and gauge how tight it is. If you like it do the other. If you feel you need more wraps pull it out and do more wraps. You can put more tape on certain sections to achieve a taper. I like to wrap mine pretty tight and put more wraps on it.
I don't think you will need pipe dope. I sometimes do both for corrosion on steel pipe threads that are going to be buried but on this you don't need dope.
I ended up doing the teflon tape with multiple wraps creating a slight taper as it progressed up the threads. Worked like a charm other than spending that time laying on my back under the sink. So far so good. Thanks for the insight!
It depends on what type of supply line you are using. I prefer the 3/8 poly supply lines, when you install them the brass nut compresses the end of the supply line to create a seal.
RectorSeal makes a liquid teflon thread sealent. Paint it on, thread it down.
