LDS Vacuum 338-200-T Conflat Flange Non-Rotatable

The LDS Vacuum 338-200-T adapter is designed for use in ultra-high vacuum (UHV) and high vacuum systems where a 3.38″ OD Conflat (CF) flange interface is required, with a 2″ inner bore for tubing or connection. The tapped-hole flange facilitates secure bolting in systems where clearance-hole designs may be less suitable, offering robust mechanical attachment.

Key features include:

• CF style flange (DN50 CF equivalent) providing a reproducible, knife-edge copper gasket seal.

• 2.00″ inside diameter through bore, allowing full flow of tubing or feedthroughs without significant restriction.

• Tapped bolt holes (rather than simple thru-clearance) for a tighter mounting interface where required.

• Manufactured in 304 stainless steel, suitable for bake-out, UHV applications, and compatible with vacuum system standards.

• Interchangeable with other CF components of similar size; LDS provides wide variety of CF338 series hardware.

Applications
This part is ideal for:

• Research laboratory vacuum systems (thin-film deposition, surface science, vacuum metallurgy).

• Semiconductor and vacuum coating systems where CF flanges are standard.

• Vacuum system expansions, retrofits, or spares where a DN50 CF flange and 2″ tubing are required.

• Educational institutions, R&D labs, and industrial vacuum setups needing reliable vacuum interfaces.

• Conversion or adapter segments connecting a CF flange interface to 2″ tubing or feedthrough assemblies.
