So use the moly grease or the red lead product?

I've never really liked to have to drill bolt holes in the viewport seating
rings. This gives me all sorts of ideas for large and small viewports. The one
thing that comes to mind with these SS Vee clamps and the SS flanges they
tighten down on, is that it creates a low oxygen mating surface that corrodes
faster, like Jay mentioned a short time ago. There doing it with the
Deepworkers and on the Triton 1000s, so perhaps it's not enough of a problem or
they are adding a coating of some sort. From: hc.fulton@gmail.com That system of 40 degree inclusive angle Vee clamps are used on the Perry subs for large Viewports. Try this lady from Teconnex as they make those clamps. England. Anyone else have a source? Hugh

It's hard to make out the hinge on the Triton pods, but you can see one on the top of the starboard pod in this rendering of the sub if you look closely and the tightening bolt on the bottom.
High pressure tri clover clamps.
From: bottomgun@mindspring.com Brent, Did not look closely at the unit that was on our pier a short time ago but from inspection of the images, it looks like the mating unit is one or the other but not both. The two-part clamping ring interfaces with beveled surfaces so that when the tighter it is drawn together, the more pressure is put on the flat mating surfaces. R/Jay

So does that mean they can be locked by both a rotating ring type,
as well as a two-part coupling flange, as it appears this DART unit can?
Are all the outer mating parts of the two-part coupling flange beveled
so they increase the pressure on the seal further as the two clam shells are
brought closer together? |
