What seacock grease?

[arch007]

hi,

What is everyone using to grease their seacocks ?

I have spartan marine bronze seacocks. Do I have to use seacock grease or can I use lanolin ?

Thanks,

I have used waterproof lithium grease, some other waterproof grease I found in a chandlery, and after rehabbing a seacock using lapping compound and grease from Spartan, their products are all I would use.

What's your particular seacock made from? For Marelon, I use what the manufacturer recommended: Forespar MareLube Marine Valve Lubricant. It's god-awful expensive, but what good lubricant isn't?

The real trick is getting it to the moving parts of a seacock while the boat is in the water! Anyone can disassemble the things when it's on the hard.

Spartan seacocks are bronze.

We always used lithium grease. Never had a problem. Pure anhydrous lanolin is way too thick and tends to attract dirt. Very messy stuff. Old timers use to use the stuff on their standing rigging screws since it does not liquify as much as other lubricants and truly is water resistant; also has no metals in it that might create other problems.
Lithium grease is available at any car parts stores and is cheap. Anhydrous lanolin can be bought at most pharmacies. Sometimes you need to ask for it at the prescription counter. It does smell like wet sheep.

I have found lithium grease gums up.

I would use what ever grease is handy that says water proof or water resistant. A grease sold for boat trailer wheel bearings should work fine.

You might want to replace one of the drain plugs with a zerk fitting so you can give it a shot of grease once in a while without taking the thing apart.

Thanks for the info ....... what is a "zerk" fitting
Is this a sea cock with a grease nipple?

Zerk fitting = grease nipple

Once you've used Spartan's seacock grease you won't use any other grease.I service far too many of these annually and I will not use anything but the Spartan grease.

Good idea, but be careful there - grease fittings are made of steel - you need to keep an eye on them. I replaced all of mine with bronze plugs, they were rusted... As a matter of fact it is pretty hard to find bronze plugs - they come with new seacocks but are not sold separately by Spartan. Most every else are listed as bronze but they are actually brass. Just my twocents.

I'll defer to Maine Sail on this. It's been thirty years since I last took apart a tapered cone seacock. In fact I don't think I've even seen one in that time.
