Anybody know about the manufacturer or repair of lug valves from this era GB? It has a tee handle tension adjuster on the opposite side from the ever handle which is held to the body of the valve by a collar with two bolts into the body.

We may not be on the same page, but it sounds like a Groco.

Got any photos?
Good luck,

Hi,
Groco SV series seacock with a rubber plug. Replacement plugs are no longer available, so service involves disassembly, lapping the plug if needed, lubrication and reassembly. If the rubber plug is too badly distorted to fit tightly, then I think the only recourse is replacement of the fitting. These are original equipment on my 88 GB36.

Thanks for the information. My friend with the GB36 has decided to haul and replace the valve as it is not worth dealing with.
