Anti seize on thru hull

I need to replace a bronze thru hull into a Wilcox-Critterden seacock. I am thinking about using copper based anti seize on the threads to act as a lubricant to make it a bit easier to tighten it down. Any possible adverse problems?

If it leaks, you will get a nice green stain.

Use Leak Lock.

Re: Anti seize on thru hull

I am really just trying to find if there is any problems with using copper anti seize, any leak in salt water will yield a green stain, and I am not worried about a leak, it will be installed properly. Is the potentially any problems, like electrolysis, or the solvents in the compound? I can't think of any, just looking for a down side.

Of course you knew about the green stain. This is just not very important.

Re: Anti seize on thru hull

No problem whatsoever. A good choice, IMO

It's a desirable step, to reduce the friction, so you can get the thread tight without any tendency for the slight asperities (inevitably on any cut thread) to bind up prematurely, and possibly to cause microscopic damage to the mating part.

Another way of saying this is: to get maximum axial force (improving sealing) while minimising torque (reducing locked-in stress)

Re: Anti seize on thru hull

I found that 3M 101 sealer makes a good lubricant. And it stops any leaks. It's also easy to remove as long as you only seal the threads that go into the valve and around the flange.

I hope not; this is what I did about 7 years back - never thought to ask if it might be a problem .

I guess I soon know

Thanks for asking

Re: Anti seize on thru hull

3M 101 sealant is no longer marketed. LifeCaulk, another polysulfide sealant, is still available. It's been my choice for caulk/sealant forever.

Anti seize shouldn't cause any problems and might make it easier to remove in the future. If you are looking for a seal, would go with LifeCaulk or some other sealant to keep the water out, however. That will still keep the parts from corrosion welding together and insure a water tight seal. It will make future removal a bit more difficult as you'll have to overcome the resistance of the caulk in turning off the parts.
