Default RE: Help - Water in the hole!

Hi Greenroom,
I think having the board level is about the best you can do.
Maybe incline it slightly nose down so the nose is not significantly higher than the vent fitting.
The water vapor is giong to "flow" toward the lowest pressure area and that should be at the vent fitting.
As far as the O'ring damage, that's what happens to O'rings when you "squash" them flat. Not what they were designed to do at all.
Maybe don't tighten the plug so tight so you don't "squash" the O'ring
so much that it cracks or splits.
Here's a link to how an O'ring is supposed to be used as a static face seal:

Since we are using a screw thread in the middle to apply the compression to the O'ring, the groove would need to be up inside the head of the plug.
After market plugs with the correct thread size would be wonderful, but I've never been able to find one.
Hope this helps,

Yes this is all useful info thanks very much.
Its the last time I buy an after market vent plug.
As I said I went into my local starboard dealer and got TWO original vent screws! Just for some info they only cost me $7aus! Not very expensive when you think how much the board costs!?

So why do some boards have vent plugs and some do not. Also why are boards made with foam that absobs water? There is foam at the lumber yard that does not absorb water and it is just as cheap as the white stuff? big Question is why with all this new shapes and technoligy have no board manufactuers made boards last longer?
