                connected together (Parker/Swagelok). <span

            <div>I am working on a list of components from Swagelok etc.

              is not too extensive but the target group does not stock
              1" swagelok components so I will have to "find" or
              purchase them. After the components are obtained the
              entire system will have to be disassembled and reassembled
              correctly to bring it into compliance.</div>
            <br>
            <div>Post assembly there is still the following work to be

              <li>System turnover to Bob Miller (assumed owner of the

            <div>The DSG can certainly help assemble the system under
              the supervision of a trained (as determined by the system
              DA) technician. They can also help with setup of the
              pressure test(s). Everything else will fall onto the DA
              and examiner with the final walk down of the system
