RE: [PSUBS-MAILIST] Passive sonar



Steve,
If you are looking for a simple gland, as long as your cable is water blocked, you can purchase stainless steal ones from McMaster-Carr. I have used the ones from McMaster on pressure balanced oil-filled (PBOF) housings down to 1000 meters. The cable has to be water blocked though. You can purchase water blocked cable from Impules, Subconn, our any connector manufacture. Falmat cable company makes the water blocked umbilcals for numerous ROV companies, they might have some in stock to purchase a short piece.
If your gland in coming directly into your sub, I would recommend a bulk head connector, unless they are pressure compensated, most will leak at or below 80 psi.
Hope this helps,

G-day everyone

 

Does anyone one in the group have any information on what type of through hull glands are used for video coaxial and power cables like those used on ROV?s or maybe subs owned buy group members?

 

Are there any good suppliers that any members know about?

 

Any help will be appreciated!

 

Regards

 

Steve Pearce
