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.

Lights for High-Vacuum Flanged Sights
Illuminate the interior of your high-vacuum chamber to clearly observe what’s inside. These lights mount to the outside of CF flanged sights with three set screws. They’re shaped like a ring, allowing you to see into the chamber through the middle. Unlike a flashlight or gooseneck lamp, they won’t block or create glare on your viewing port.

High-Vacuum Sights for Quick-Clamp Fittings
Designed with quick-clamp (KF) connections, these sights connect to a port on a high-vacuum chamber, so you can monitor what's happening inside. A sleeve seals the glass window to the body of the sight to prevent leaks. To connect to your chamber, you'll need a clamp and a ring (sold separately). Not for use in pressure applications.
