Viewport fitted doors are constructed with Corning type 7056 glass fused to a Kovar® nickel-iron transition sleeve. All access doors are supplied with Viton® elastomer seals suitable for high vacuum service. High temperature Kalrez® elastomers can be used to increase a door's maximum temperature rating.

Quick-Access doors with clearance mounting holes are intended for installation on chamber ports with tapped holes. To order this hardware, reference the hardware table below.
