Enable quick and convenient access into vacuum vessels, such as process chambers and load locks.

Features

  • Offered in a wide range of UHV flange sizes, with or without viewport glass
  • Precision-hinged access doors seal with a fluorocarbon o-ring
  • KJLC's® unique counterbored mounting bolt design enables a maximum diameter opening through the door (order appropriate socket head bolt sets and kits below)
  • Viewport glass is sealed with an o-ring and is easily removed for cleaning or replacement
  • Threaded knob is engaged to keep door closed during pumpdown
  • Comes standard with Tempered Pyrex viewport glass. Replacement Quartz glass available.

NOTE:

  • It is recommended the knob be disengaged during the vent cycle to prevent overpressurization of the vessel.
  • For more information, please go to Fast-Entry Access Doors Hardware.
