Copper will work harden and fracture as Willie has said, which is one of the reasons it is illegal to use it for brake lines in some countries.
Steel with a rubber flex section like the factory used is possibly the best compromise.
Whatever you use, it is best to keep the bore as small as possible so that the gauge wil work faster, and less oil will be pumped out in the event of a failure.

What mechanical gauge did I use? It was a TIM full sweep 100psi gauge (still for sale)
I replaced it with my Innovate G3 series gauges. It's the gauge in the middle. You'll notice how it's dancing around. I had a sticking plunger and I actually shot the video to show what it looked like. Nevermind the loose belt. haha.
All three gauges are used as diagnostic tools. Not just for looks.

You're definitely not wrong, Willie. I think if you're careful, they can last. If you ask me, they all will fail in some mode or another eventually. I've had pressurized oil spurting behind the dash before and it's not a fun fix on the side of the road. All of this is what ultimately led to me getting an electronic gauge. Failure mode is usually gauge stops working or a slow oil drip. Both are still driveable.
Just offered up my piece to OP. There's almost always more than one option.
i am careful. i twisted a lot of nuts n bolts in my day..the issue i think may lie in the fact that all this sh-t is made off shore...
i went to the store,, looking for fittings . wtf.?? hey mark? wheres all the fittings at..?? we had to pull um all..what..?? yep..not sized right , to soft...no sh-t..?? yep. the supplier said pull um..
don't know where the copper tubing was made at....??? all this off shore sh-t is crap.. piss's me off..
ya know man... i'm just ol school on mechanical gauges...in my mind.. i think there more accurate...?? i get autometer...at least for now there still made on my soil..

Used a copper line with yellow teflon for a little over 5 years with zero issues.
kudos to you and all that....
not me.... ever again..... seen 2 copper lines break from vib. at the nut.
seems if you over tighten the nut to the gauge , when squishing the ferrule , it weekens the copper line at that point... the wall thickness is now thinner ..... and thats what happens ...
a stainless steel braded line for that might be 20 to 30 bucks and no worries......

I used the yellow Teflon tape made for petrolium lines on mine and haven't had a problem since.
