Hands down the Spartan grease... It's as thick as cold peanut butter and formulated specifically for tapered cone seacocks...

We use the grease and lapping compound from Spartan also and like it very much.

I also use it for stainless screws into aluminum, good stuff, You used to be able to get it from Avon, Ive had a tube all of my life, a little dab will do you.

Mainsail has you covered regarding your tapered valve seacocks in this article.

We have bronze ball valves so we use the specified Lubriplate 130-AA grease [which I understand is also specified for some feathering props.]

I paint it on the ball valve from under the vessel when on the hard. [It is faster to have someone cycle the valve from above while I paint it on from below...]

I'm also a big fan of lanolin, but as Cheechako mentioned, it gets a bit stiff in colder waters, so I use the Lubriplate 130-AA to keep them moving easily and freely. [It helps keep the hard growth away as well- as does any grease...]

Cheers!

Bill

long time ago I watched a movie named das bot about a German u2 and I remember the engineer running around the sub with a bucket of Vaseline and a stick in it and he used it on everything in that rust old bucket. Since my younger days I've used it everywhere electrics through hauls etc.

Aqua Shield is used on oil rigs. Don't get it on your hands, as it really is water proof hard to clean off. I use it for all areas that require grease on my boat including my winches, make sure you wear rubber gloves as it is very very sticky. d-a-stuart.com*-*This website is for sale!*-*d-a-stuart Resources and Information.

Re: Best grease for bronze seacocks?

Forespar sells Lanocote which is lanolin based AFAIK and what we use on seacocks and turnbuckles. We're in the tropics so no problems with cold, but I never heard about it not being okay for cold climates.

I wonder what the Spartan grease is based on? Wouldn't be surprised if it has lanolin as well.

Vasoline is petroleum jelly so I would not recommend using that when there are any plastic parts, like the ball or seals in a valve, involved.

Re: Best grease for bronze seacocks?

I was doing a plumbing job at the house and it occurred to me that ordinary Plumber's grease used for the modern brass-rubber composite equipment is probably a great option. Stays put, waterproof, non-toxic - less cost than anything designated for boats.

Re: Best grease for bronze seacocks?

This search on Defender shows they now promote a Teflon based lube for valves while also still having the Lanocote product.

The Teflon based sounds a lot like the SuperLube I also use.

I don't know of any distributors, I just order it from Spartan. One tub will last years. I can do five to seven boats on one tub.. I have no idea why you would transfer it to a gun as this is a manual application. The screws on the side are drain screws for winterizing and are NOT intended for greasing or for grease zerks..

Directly from Groco service manual:

"BV seacocks are fitted with one
drain plug and one zerk fitting. The zerk serves
as an additional drain plug but also provides for
the injection of GROCO U-LUBE lubricant into
the space between the ball and the valve body.
U-LUBE (available in 3-oz or 14-oz tubes) is
specially formulated for ball valves to lubricate
wear parts and to discourage the accumulation
of nuisance marine growth."
