Small seacocks?

Does anyone make seacocks smaller than 3/4'' (like 1/2'')? I have salt water intake for the galley foot pump that is currently 3/8'' with a ball valve, but would like to be able to bolt to the hull with a seacock. It's in a locker that will like be full of canned food bouncing around.

I just replaced a 1/2" thru hull/seacock with 3/4" because I wasn't able to find anything smaller. The old thru hull was flush on the outside, an appropriate sized hole saw for a 3/4" fit over the entire flange of the old 1/2" so I cut it out from the bottom which made installing the 3/4" a piece of cake.

Forespar has a 1/2" seacock in Marelon. I have a couple of Marelon seacocks on my boat and they have proven to be robust.... strong enough to counter flying cans of pork and beans?? Not sure.

Here's a link.

Seacocks vs Ball valves..

I understand bolt-on seacocks are used instead of ball valves, but given that thru hulls have a nut holding them in place how do the seacocks install? I've had my C&C for a half dozen years & it came with ball valves installed. Even the 2 last original gate valves which I am not removing simply thread onto the thru hulls, no flanges.

TommyD,
Seacocks thread onto the through hull fitting and then secured to backing plates with through bolts. The backing nut on the through hull fitting is not used. Mainesail has a great website providing detailed information on this here:
