The cult of the Proper Flanged Thru-hull

You’re on your own, nobody is coming to help, it’s up to you.

Jedi you nailed it so perfectly right there in this post

This is very common on US sailboats \.

"Very Common" BAHAHAHAAAA Now THATS FUNNY !!

Your whole earlier rant was on "bonding thru hulls" and thats why they are failing --- Man you really change your stories alot ! LOL

Even still I have never see that, If its out there its very rare without Galvanic Isolaters !-- Go ahead right now, name the Boat and Manufacturer that is doing that without galvanic isolators !

I keep posting with facts AND at least I have corroborating data -- I'd like to see more than bloviating. You haven't posted anything to back up anything you've said.

From memory I’ve seen in on a passport a hunter , a tartan and an island packet. Cant think of the others I’ve seen it on , I was in a Hinckley and a Morris but can’t recollect.

I’m specifically taking about equipotential bonding as Laid out by ABYC

( though ABYC gets grounding and bonding mixed up together. That’s part of the issues )

However, after twice assembling two fuel manifolds, using 8 valves, (3/8ths pipe size,) that leaked from the valves, I replaced the Italian valves with ones from Apollo, (the one on the left,) no leaks.
You can easily see the difference in robustness between them.
When fittings were tightened into the Italian valves the thin shells simply expanded which ruined the seal, or the male threads bottomed out before a seal could be established.
I know it's but a sample of a few, but much of what I've encountered in European boat fittings, (and the boats themselves,) are what might be referred to as "Effete" construction.
Kind of similar to the leather jackets and shoes they make, striving to make the leather as thin as possible, to be "fashionable".
Oh, the Apollo valves didn't cost that much more, the Italian valves went in the scrap metal bin.
I'll admit to some bias, but I'll also cast a close look at any boat fitting from Europe that needs to be "heavy duty"
