[PSUBS-MAILIST] Skadoc Question

[Alan via Personal_Submersibles]

James,
Emile & Carsten use the blue globes & double up with one on the outside of 
the through hull & one on the other. I believe as security so that the cable
doesn't extrude through under pressure.
I am wondering how they last over time being some type of plastic. However easy 
& cheap to change out.
Also a lot would depend on the cable you are using as to how well it would seal.
I am making my own. I made them for the back of my lights & tested them to
2000psi. 
If you look at Dougs videos on making & testing through hulls on "submarine boat"
you can see that home made penetrators are a bit trickier than they look.
