[Public-list] thru hulls and seacocks and ball valves

[barchettamia at pinelink.org]

>At the time I did my research, about 7 years ago I contacted Conrbaco

or steel component , or both. I don't know about Buck Manufacturers;
certainly an all bronze ball valve would be a useful product. What I
would like to see made is a bronze pipe nipple.

 Apollo had an a issues few years ago using a brass ball in there product.
