Default Tight SS ball valves

My SS ball valves are with varying degrees hard to turn. Only the newer ones that I bought from Bargain fittings are easy to use. The older ones really need a strong arm turning them. Can I take the nut off and oil anything or would that break some internal seal that keeps it water tight?

I presume that you have a 2 part body valve. First, close the valve and look at the ball. Make sure there are no scratches or cuts in it. If there aren't, I wouldn't take the valve apart. I would put oil on the sides of the ball and operate it to see if it will loosen up. If not, contact the manufacturer and see what they recommend. Luck - Dwain

I would try a little teflon base grease that is a light blue in color and like Mayonnaise. A light coating and work the lever to fully to coat the ball then clean it off.

The other lubricant that I would use first is that Epic bicycle chain lube that after the solvent quickly dries it leaves behind a wax base which should not leave any bad taste in your bier. This is also sold as White Lightening at your local bicycle shop. A dry waxy film I can see no problems with.
A household lube for hinges, latches and striker plates. No oily or dirty clothing makes the wifey happy.

I personally would use Keg lube.

I wonder if there is wort getting between the seal and the ball.

I agree with using keg lube, I doubt the bicycle grease is food safe..

Do not use bike chain grease!!!! Wax based greases cannot be good for beer, and that stuff tastes very very very horrible and is extremely potent.

Thanks for all the ideas! I went with some keg lube and it worked well. Will be interesting to see how it holds up under the heat of the boil.

Dwain - I don't speak Chinese or I would contact the manufacturer and ask them why they don't lube them.

For one thing it is not a "grease" second it is a wax film just like a candle, paraffin base candle wax which has no taste. We have been using it for years with brewing friends without a problem.
This is what we use and the transfer solvent is dry within two minutes.
Now to drink the lube with the transfer solvent is flat stupid as well it is highly flammable hence the fast evaporstion rate.
Sorry for bring up what has worked trouble free for us for years.

That above quote is total B/S but then use what makes you happy.
Billions of candles in use without deaths and the above said "tastes".
I'm out of here on this reply. Again sorry to have mentioned such a "tastes very very very horrible and is extremely potent" product as a household candle is so common. I must get Ralph Nader on this one as he can save the world on this new and "extremely potent" product.

Wow. I didn't mean any offense BrewBeemer. I am just saying that white lightning tastes really bad. Maybe it doesn't if you let it dry, I have never tasted it dry. That stuff smells and tastes bad in liquid form though.

Apparently it works, I would still go with a made-for-food product though if I were you.
