All our threw hulls get opened and closed a few times a year. I assume the seals in them are Buna. Looking up Buna it is not effected by corn oil #4 on compatible scale 1 to 4.
I used to work in the oil business and saw the effect of oil on Buna. It swells. So do not want o lubricate with oil based product.
Question
Our boat is stored on land when not in use. I was thinking of closing threw hull valve and pouring corn oil down the piping to the valve then working the valve open/close to lubricate the valve.
Dumb idea? At least I would be using a non contaminating lubricant.
Does any know the material used in marine valves?
Is there a product made specially for marine valves?
