What Are Vacuum Fittings?

Vacuum fittings are components used to connect pipes, chambers, pumps, valves, and related equipment in systems that require controlled pressure and reliable sealing. They are essential in applications where leakage control, structural precision, and material performance directly affect system stability.

Wellgrow offers vacuum fittings and components that help customers build and maintain vacuum systems with dependable assembly, clean performance, and long service life.

KF, ISO, and CF Vacuum Fittings

KF Vacuum Fittings

KF fittings are widely used in low to medium vacuum applications that require quick installation and convenient maintenance. They are suitable for laboratory systems, instrumentation, and many general-purpose vacuum lines.

ISO Vacuum Fittings

ISO fittings are commonly used in larger vacuum systems where greater flow capacity and larger connection sizes are needed. They are often selected for industrial vacuum chambers and process equipment.

CF Vacuum Fittings

CF fittings are designed for high vacuum and ultra-high vacuum environments. Their metal-sealed construction makes them suitable for demanding applications such as semiconductor processing, advanced research, and systems where very low leak rates are required.

If your application requires a more specific finish or quality expectation, our team can discuss the appropriate option with you.

Selection Support

How to Choose the Right Vacuum Fitting

Choosing the right vacuum fitting depends on the system standard, pressure level, connection size, material requirement, and application environment. When selecting vacuum components, customers typically consider:

• Whether the system requires KF, ISO, or CF connections
• The required vacuum level and sealing performance
• The material best suited to the process environment
• Cleanliness and surface finish requirements
• Compatibility with chambers, pumps, valves, and existing piping

If you are not sure which specification is best for your system, Wellgrow can help review your application and recommend suitable options.
