[PSUBS-MAILIST] cable fittings

Rick,
I would go to 2 fittings but I don't think you would get twice the holding
power. I think they are designed to take the pressure in one direction more
than the other. But it would be an added security against leakage or a catastrophic
failure of the outer blue globe.
As said Emile & Carsten have had them in use for a while.
If you contact them on messenger (Facebook) they may give you more detail.

They did tell me that by going up to the higher rating (30 bar) that it was only made with metric threads and I have already welded in my threw hull fitting for a 3/8" NPT but they are checking on that. What do you think about using two fittings to get twice the amount of holding power?
