Hi Tobin, Are you interested in providing me a quote to make some PSCR switch blocks. I have full AutoCAD drawings of course. They are just too expensive to have made here in Australia and a number of members have contacted me asking if I'd be prepared to make a few. Initially a quantity of ten units, if you could provide a price with and without the valves and fittings, I'd appreciate it. Here is a link to some pictures of the one I had made here in Australia: http://www.rebreatherworld.com/pscr-...itchblock.html The Valves are Swagelok SS-4P4T for the green one and SS-4P4T-RD for the red one. New o-rings for the valves are 012 and 3-902 EPDM or Viton in 90 duro. Quick connects are SS-QC6-B-4PM. To assemble it, you need to use Stainless teflon tape, which is silver in colour. You can contact me at divingtactics@gmail.com if you need anything else. Thanks, Jason Caldwell
