Alcatel 2C7‑1005‑000 Teflon Bell Jar Holder Ring – Part 146111

The Alcatel 2C7‑1005‑000 is a precision‑engineered Teflon (PTFE) ring used as a bell jar holder and sealing element in vacuum deposition systems, thin‑film coating equipment, and semiconductor processing chambers. Also referenced as part number 146111, this component provides a reliable, chemically inert interface between the glass or metal bell jar and the chamber base, ensuring vacuum integrity and mechanical stability during operation.

PTFE offers exceptional chemical resistance to acids, bases, and solvents used in cleaning and deposition processes. It also exhibits low outgassing properties, critical for maintaining ultra‑high vacuum levels. The ring is machined to tight tolerances with a smooth surface finish to prevent scratches on the bell jar and ensure uniform compression of the O‑ring seal.

This component is a direct replacement for original Alcatel vacuum equipment and is compatible with a range of deposition systems used in research laboratories, solar panel manufacturing, and semiconductor fabrication.
