Using a galvanized/metal nut?

So my PPW (pool problem of the Week) is this: yesterday i got home from being out and about, wanting to go for a swim. i noticed some water dripping from around the pressure gauge. meh, nothing to worry about, so i turn on the pump...

WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOSH!!!!!!!! the gauge goes flying out and i'm left with a pretty nice sized waterfall. the nut that holds the pressure gauge in place is broken. said the heck with it and we all went swimming anyways (after closing off the valves).

after calling every pool store within a 50 mile radius and NO ONE having the replacement part or anything similar, I went to Home Depot. Eventually between a mix of O-rings washers and a metal nut from the plumping section, we found pieces that work pretty flawlessly. as in, I put everything into place, and there isn't a single drop coming out of this area. it's sealed. pump is running for a few hours now.

NOW, is there anything I should be concerned about with using a metal piece on the plastic body (esp since I have an SWG)? Could any of this lead to rust or other issues?
 
Brass is an alloy of primarily copper and zinc. It is highly corrosion resistant and electrically conductive. However, its use as a fastener is somewhat limited due to its relative softness. It is used primarily for its appearance.

The biggest risk to a galvanized bolt/fastener is if the protective coating gets nicked. If this happens, it can set the stage for some rusting. Just keep an eye on it. If it begins to rust, I would replace it with a stainless steel one. If it will make you a bit more at ease, next time you are at the Depot, I would look for a stainless bushing while it is still fresh on your mind. With a relatively low cost item like this, it doesn't hurt to have a spare. As I have often found, if you wait until you need it, you may have a hard time finding it.
 
If it was the gauge that broke, Home Depot should have them. They are where the well pumps are sold. I don't think that galv plug is going to be a long term fix. The brass ones are in bags probably on the same isle.

EDIT: just looked and saw it was a bushing. Yea I would go with brass or SS. Like I said they should be in bags. Watts is what my Home depot have.
 
thanks folks - i do see a chrome plated one at HD's website, but no stainless steel. Amazon has it - will get a spare to keep around, for when the galv. one fails (if it does). since it's pretty buried in the filter, don't see it getting nicked, but knowing my luck, it will find a way.

Galvanized will not last long in a pool environment. It will rust and that rust can make iron stains. Especially if you have returns that come out near fiberglass steps.

Is this the part you need?

thanks - i found those ... last night when this all happened, but figured by the time i get it, the pool would be green again. given what you guys have said here, i will still order from one of these places, and keep the HD one as a stop gap until that arrives (so that I can at least run my pump). my return is literally on the other end of the fiberglass steps (which already has some rust stain from before).

for the price or the part, better to shell out the cash now and consider it preventative maintenance. last thing I need is more complications.
