Question About Using Teflon Tape

At least I think that is what my question is.

I got a new water pump">raw water pump for my engine, the old one was leaking and a couple of components had rusted.

When installing my new raw water pump, I found that in order to get the water output nozzle pointing in the only viable direction for attaching to the hose, the tension on the nozzle is not as tight as it could be, and a very small amount of water (one drip a minute perhaps) leaks back through the threads.

Before putting the nozzle on I cleaned the threads with a wire brush and put on some teflon tape.

To make the seal as tight as it should be - and pointing the right direction -can I just use more teflon tape? As it is, I can't get the nozzle to go a full extra revolution.

thx

Don't you hate that? It seems every fitting we have points the wrong way when properly tightened.

Your idea would probably work, but a better solution is to use pipe thread dope or even caulk like RTV silicon. It will fill the loose spaces better. The pump isn't under pressure, so no worries about holding. Let it set up before using.

I'd use the heavy tape that's commonly used for gas (natural and propane). It's on a yellow spool. I've used dope before, but I really like the heavy tape.

a few more wraps of teflon will work. I know because I have done it. just make sure you wrap it the right direction .

I keep a can of dope on-hand. Fittings of different materials should always be joined with the flexible dope. Dope is also useful as a non-crucial thread loc (as is Teflon tape).
