LDS Vacuum 338-150-R Rotatable Conflat Flange

This LDS Vacuum 338-150-R is a high-vacuum compatible Conflat (CF) flange assembly featuring a 3.38″ outer diameter knife-edge flange and a 1.50″ tube bore. Designed for use in high-vacuum and ultra-high-vacuum systems, this unit offers a rotatable flange configuration (clearance thru-holes) allowing easier alignment of connections within vacuum chambers or piping systems.
Constructed of 304 stainless steel for corrosion resistance, the flange features standard CF knife-edge geometry and is compatible with copper gaskets and standard CF tooling. Ideal for vacuum applications where precise alignment and reliable sealing are required (e.g., research labs, semiconductor processing, vacuum coating systems, scientific instrumentation).

Key features:

• 3.38″ (≈86 mm) outer diameter CF flange

• 1.50″ (≈38.1 mm) tube/bore size

• Rotatable design (-R suffix) for thru-holes for improved alignment

• 304 stainless steel construction

Ideal for: Vacuum system OEMs, laboratories, research facilities, process engineers looking to replace or upgrade vacuum plumbing parts, CF flange systems, UHV setups.
