    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.
