<div>Just an FYI I use mineral oil in everything including hydralek hydraulic skid and it has a rubber bladder external for compensation she's been working full time for four years without any problems I buy it by the 5 gallon pails at McMaster Carr they have two grades one is very thin witch is what I use in all the Rov motors </div>

<div>Scott,</div>
<div>Sorry you have these problems with conference looming.</div>
<div>I did tests on WD40 a while back & found it dissolved some plastics. It was used in some</div>
<div>Sub motors. And even if it mightn't dissolve plastics relatively quickly, these oils / spirits could do in time.</div>
<div>The professional compensating units used on ROVs are a spring loaded cylinder</div>
<div>that pressurise the oil to about 5 psi, however the pressure drops as the spring</div>
<div>expands. If you Google ROV compensating unit you may find some. I've seen them for sale</div>
<div>But they cost an arm & a leg.</div>
<div>Carsten & Emile are now using a low viscosity high priced silicone oil.</div>
<div>Not sure what they are using but I believe you can get silicone oil at a viscosity similar to water.</div>
<div>I air compensate my motors, but have been told oil compensating is safer because</div>
<div>It is more forgiving if water gets inside the motor, also there is the danger of stuffing your motors</div>
<div>& losing your ballast air if there is an air leak.</div>
<div>Sorry, this is a bit of a rave, hope it is helpful.</div>
<div>Regards Alan</div>

<div>I'm not a big fan of gaskets or flat disc viewports in any case, but 12,000+ dives for the Nektons is a pretty good statement. They work. Do not use straight neoprene gaskets, and I suspect that unglued urethane gaskets fall into the same category. They are too soft and will extrude to the low pressure side.</div>
<div><br></div>
<div>Side note: I HATE using silicone sealant in this kind of application. It works fine, but makes maintenance impossible. If you're going to do it, then just go ahead and build some extra viewports. You'll need them for replacements the next time you paint.</div>

<div><font size="2" face="Arial">I'd prefer to have all conical viewports and I don't think you can properly gasket a conical viewport. A rubber O-ring that seals at the edge where the lens meets the seat is as good as it gets on a conical viewport. The shape of the cone and the pressure on the big side of the cone ensure you'll never have a gap to extrude the O-ring. If it wasn't so difficult to machine the viewport seats conical after they are welded, I would have used all conical lenses and O-ring seals. It's impossible to hold the seat true if you machine a cone first then weld.</font></div>
