[PSUBS-MAILIST] strain relief fittings

[Rick Patton via Personal_Submersibles]

Thanks Ian

Maybe I am being over protective now because I didn't pay enough attention
before and got under rated fittings. I couldn't find a diffident rating for
the IP 69K as far as bars or psi goes but this data sheet spells it out
better.
Thanks

Rick
