These pics come from a new aerospace test facility that they are constructing at the University of Notre Dame. The SSF-6 is working great.
I am attempting to make all of these fittings air tight as they are used for pressure measurements. We can¹t have any leaks. I had very little warpage of my base metal and I think this is really going to work out very well.

Copper nickel or cupre nickel is a widely used alloy in the marine industry, due to its seawater corrosion resistance. It is typically composed of 95% copper and 5% nickel, 90/10 or 70/30 depending on the need. Many boat hulls, heat exchangers, condensers, hydraulic lines, and piping are manufactured with copper nickel, as it also has a high resistance to biofouling.
Copper nickel tubing is flared with the tubing inside one another. SSQ-6 can be applied to the tube either before or insertion.
SSQ-6 works best when applied to cold metal. Simply press the plunger to apply the paste.
An even heating method with a propane torch creates a very strong water/air tight seal.
After cleaning with water and a wire brush, there are no pinholes or porosity.
