Vacuum Fittings: Elbows, Tees, Crosses, and Cubes

Vacuum chamber fittings, including elbows, tees, crosses, and cubes, are essential components used in vacuum pipe systems to connect straight pipe or tubing sections. These fittings are meticulously designed and manufactured to meet the stringent requirements of ultra-high vacuum (UHV) standards and are compatible with ISO, CF, and KF face seal flanges.

Types of Vacuum Fittings:

1. Elbows:
   • Vacuum elbows typically feature a 45-degree or 90-degree bend, allowing for a change in the direction of a vacuum pipe system.
   • Commonly used with welding vacuum KF, ISO, and CF flanges for seamless connectivity.
   • Example: The elbow fitting extends from the vacuum pipe fittings of the chamber, facilitating pumping processes.
2. Tees:
   • Vacuum tee fittings have one input and two outputs (or vice versa), intersecting at 90-degree angles.
   • Available in standard designs where all outlets/inlets are the same diameter, as well as reducing designs with varying sizes.
   • Used to branch off a vacuum pipeline or to join multiple pipes together.
3. Crosses:
   • Vacuum cross fittings have one input and three or more outputs that intersect at 90-degree angles.
   • Mainly available in 4-way, 5-way, and 6-way configurations.
   • Used to connect pipelines at various angles with the main line, providing versatile routing options.
4. Cube:
   • CF cubes for ultra-high vacuum systems are constructed from 304 stainless steel material, forming a one-piece block with CF flanges for pipe connections.
   • Six-way cube cross fittings have one inlet and five outlets, serving as cross branch lines in complex vacuum plumbing systems.
   • Commonly used in vacuum chamber process systems to build robust and efficient vacuum plumbing configurations.

Materials and Compatibility:

• Vacuum fittings are available in materials such as 304 and 316 stainless steel, ensuring durability and compatibility with diverse vacuum system requirements.
• Precision machining ensures high and ultrahigh vacuum compatibility, meeting the stringent demands of vacuum chamber operations.

Applications:

• Vacuum fittings are indispensable in various applications, including research laboratories, industrial processes, and semiconductor manufacturing.
• They facilitate the construction of vacuum plumbing systems, providing reliable connections and precise routing for optimal vacuum performance.

Vacuum chamber fittings, including elbows, tees, crosses, and cubes, are essential components in vacuum systems, offering versatility, reliability, and compatibility with a wide range of vacuum flange configurations.
