brass copper or stainless trim rings

I,am refitting a 1982 Cabo rico,the Perko ports are secured by tap screws into the coring for strength,The out side has a trim ring which also acts a sealer for the caulking.it is aslo taped into the coring from the outside.Thus they are not thru bolted.I,spoke with a metal shop today and the ablity to make a full sized trim ring is available,Thua allowing thru bolting.
Any ideas on which material to use Bronze is out of the question since the Ports a forged.Stainless,Brass,or Copper that is the question.
Strength is not really an issue as the rings will only have compression and will be secured with sex bolts.My curiosity is any experience with ageing which will match the bronze as the rings age.
Any and all views wil be apppreciated.

Just make sure you match the sex nuts with those bolts.

New sex bolts are hard when they need to be and soft otherwise. Older sex bolts remain soft and is a good indication that replacement is necessary.

Re: brass copper or stainless trim rings

I'm some what confused. Why do you need to make new trim rings? Do the existing holes in your current trim ring not line up with the holes in the ports flange? As a word of caution, never say "sex bolt" in front of this crowd. You'll never hear the end of it.

Re: brass copper or stainless trim rings

GeeeZOO PeteZOO,Must be a lot of ___ deprived folks looking for stimulation,I,am Happy to provide a little Cheer.Next time I'll use Male and Female joiners.
The way these ports are constructed the outter trim ring is smaller in diameter on the outter ring can not be drilled thru to meet and thru bolt.I,like the old Perko Ports real green and salty looking plus there massive.Thus the question which metal to make trim rings from which of the three will look best and resemble the Bronze port.
Have a GOOD Day All

Casual,

A picture will help us all understand what you are trying to do. Can you post a shot of your ports?
