I have old tubes and new hinges, but nothing else.
Lang's filler blocks are aluminum. Chaffin catalog doesn't say. Would aluminum be healthy inside the brass?
I was wondering the same thing. Galvanic corrosion will eventually be a problem between these two metals, but it may take a very long time. I might coat the aluminum plugs with something prior to installation.
You can buy a lanolin containing grease at marine stores. One brand is Lanocote. I use it on my boat all the time to prevent corrosion between to different metals.
Iron filler plugs and brass tubes is a better combination. But, If you do use aluminum, it will corrode before the brass does and leave the brass intact. The grease sounds like a good idea to keep the joint dry.
Also a very good one @ pool supply stores called Jack's. Seems to be silicone-like but doesn't harden or wash away. Expensive but will take heat or cold . John
I have a box of various cast iron windshield filler plugs. Come visit me in Fallbrook and see if you can find some filler's that will work. The price will be right....free if you do the digging.
Thanks, Les. I just may do that, enroute from the Sandy Eggo swap, if not sooner.
