Sea Cock questions

OK...I'm a valve guy and need to replace some old blakes seacocks. Cost of these is a bit much and have looked for ball valve type sea cocks only to find that even the UL approved for marine service from the likes of Conbraco (Apollo), Buck, Groco and I believe Watts, all have chrome plated brass balls. I don't understand the lack of proper bronze. Am I missing something?

Re: Sea Cock questions

My preference are the new bronze seacocks with teflon-coated balls. Less prone to mechanical freezing.

My preference is Groco, no matter what ball they put in. I have one for 10 years now that works like day 1.

That's pretty much what I just said.

Re: Sea Cock questions

I just installed a new Raw Water Seacock with a Groco. As soon as I have the time/money, I'll replace all the old seacocks with Groco.

Whatever the ball that's used, it still seems to be a pretty good product and has a real nice smooth feel to it when opening or closing the valve.

Re: Sea Cock questions

I asked Groco about using a chrome plated brass ball. They said it is a very heavy chrome finish and it protects the ball. These chrome plated brass balls have been working in the real world for many years, more than twenty on my boat. I think the Groco is the best value in a seacock on the market today.
I like that you can use a socket wrench to extend the handle if you have to. I also like that you can move the handle stop so that it will work in either direction.
I think if you visit my website you'll find I have pretty good pricing on them.

Re: Sea Cock questions

Rhapsody - Nice job using the flanged adapters. Thanks for buying the tool from me!
Where do you get the G10 fiberglass board? Who makes it?

Re: Sea Cock questions

Thanks,

I got the G10 from jamestown distributors. I looke around at different sources but looked like JD was pretty good with pricing.
