LDS Vacuum 462-300-R Conflat Half-Nipple, Rotatable

The LDS Vacuum 462-300-R is a precision-engineered ultra/high vacuum component designed for demanding laboratory, research, and industrial applications. It features a 4.62″ (117.35 mm) outer-diameter Conflat (CF/DN75) flange integrated with a 3.00″ (76.2 mm) tube OD, all in a 304 stainless steel construction for excellent vacuum integrity, durability and compatibility with UHV systems.

Key attributes include:

• Flange size: 4.62″ OD Conflat (≈ DN75CF) — a common vacuum standard size for large-bore systems.

• Tube OD: 3.00″ (76.2 mm) — providing a robust flow path for vacuum or process gases.

• Material: 304 stainless steel — suitable for clean-UHV environments with good corrosion resistance.

• **Rotatable half-nipple design (“-R” suffix) — allows flange orientation adjustment without compromising alignment, aiding in ergonomic installation and alignment in complex vacuum rigs.

• Mounting holes: ten clearance (through) bolt holes (typical for 10-bolt DN75/CF462 size) for secure flange mating and effective sealing.

• Typical use-cases: vacuum system expansions, vacuum chamber feed-throughs, UHV instrumentation setups, research beamlines, process vacuum manifolds — especially where the combination of large bore, rotatable orientation and high-vacuum flange integrity is required.

Typical Applications:

• UHV research chambers (surface science, thin film deposition) where a large bore feed-through is required.

• Vacuum instrumentation and analytic systems (mass spectrometers, surface / material analysis) needing a large Conflat interface.

• Process vacuum systems in educational institutions or research labs where flexibility and modularity are needed.

• Expansion of vacuum manifold systems, pump capture volumes, or vacuum storage chambers.
