Those are showing up surplus. They and the SSI company are old OLD school, out of business. IMO... I would be careful in its use.

It's a bit of an odd one. I was given one as an "engineering sample" Was hermetically sealed (soldered housing) and a pain to crack open.

i do believe that SSI box is a single component box, meaning it uses no TSU or GPC in the water crossover .
they are garbage…toss it in the garbag.
