Jordan, Janos, 04-24-2025, ~15:00 The wire gaskets for VBO-C and VBO-D have been leaking continuously for a very long time. Lots of vendors have been contacted, and after a lot of unsuccessful tests, it seems that we finally found the good one manufactured by Torr Scientific (UK). This gasket is extremely annealed, butter-soft, needs super careful handling, but even after some suboptimal installation steps (mea culpa), it finally sealed a new chamber successfully. We tested it right after receiving (had a thriller with customs) with a new C+B chamber, pumped it down and tested on the same day. After the test, we let the pump running during the weekend just to see the ultimate pressure it can reach. They are still very pricey though, 193 GBP (= 257 USD)/pc., even in the case of purchasing 100 pcs., it's 147 GBP (= 196 USD)/pc. So, certainly not an optimal, long-term solution, but a good bridge between having nothing and manufacturing our own.
