Blank CF flanges serve as sealed port terminators in vacuum systems used for semiconductor processing, PVD (physical vapor deposition), and CVD (chemical vapor deposition) chambers. The Conflat design provides reliable ultra-high vacuum sealing when paired with matching flange components and standard CF gaskets.
Condition: Used
This MDC vacuum blank flange has been inspected and is in good used condition. It was pulled from a working vacuum system. The stainless steel surfaces show light oxidation and minor surface discoloration consistent with age and prior use in a vacuum environment — the machined sealing faces appear intact with no visible damage. The photos show a light spot on the top face and some discoloration on the outer flange ring, but no cracks, deep gouges, or deformation. Please view our photo set and contact us if you have any questions.
