[Alan James via Personal_Submersibles]

That's OK, sorry I wasn't much help.I have book marked this sitehttp://prevco.com/products/subsea-housings/seal-configuration/single-face-seal
They are experts in sealing underwater housings. There are several examplesof sealing methods, & their pros & cons are discussed. Alan

I think they would work better externally Alan the wet switches are a must ,but I must admit the pod seal arrangement gives me sleepless nights.I have also just cut my CT off and re mated the hatch and re cut the o ring groove to hold a 9 mm od o ring. Maybe I am getting a bit paranoid. As to the cricket looking good, do the Americans actually play unprotected sport?

Another thought Glen,those seals for pipes would be designed for internal pressure.Are they OK for external also?Alan

AlanIts 316 ss ,I was thinking of assembling with grease there is more than enough space to fit it ,you get some of the fittings with triple seals up to 2000 psiGlen.

Glen,as long as salt water doesn't sit in it after a dive& cause corrosion. ( I suspect it must) Or clamping it on doesn'twear in to your paint work & expose the metalalso to corrosion.Alan

I am planing on as an "extra safety" for my K350 B pods end caps ,covering the join between the end caps and the pod with a hp pipe join coupling.
Any comments most welcome. Glen
