High-Vacuum Flanged Sights
Add a window to your high-vacuum system. With a pane of glass sealed inside a high-vacuum CF flange, these sights bolt onto vacuum chambers, tee fittings, and manifolds. Use a copper gasket (sold separately) to create a seal. Not for use with pressure. To illuminate dark interiors, attach an optional light to the flange with set screws.
