Component Specifications

Definition
Vacuum ports are precision-engineered interface components integrated into vacuum processing chambers, designed to maintain ultra-high vacuum integrity while providing access points for pumping systems, pressure gauges, leak detectors, and other vacuum instrumentation. These ports feature standardized flange connections with specialized sealing mechanisms to prevent atmospheric contamination and ensure consistent vacuum levels during industrial processes.
Working Principle
Vacuum ports operate by providing a sealed transition between the vacuum chamber interior and external systems. They utilize precision-machined flanges with elastomeric or metal gaskets that compress under bolt torque to create vacuum-tight seals. The port geometry minimizes conductance restrictions while maintaining structural integrity under pressure differentials, allowing efficient gas evacuation and process monitoring without compromising vacuum quality.
Materials
Stainless steel (304, 316L), aluminum alloys (6061-T6), with optional electropolishing or passivation. Sealing surfaces typically use Viton, Kalrez, or copper gaskets for high-vacuum applications.

Frequently Asked Questions

What are the main types of vacuum port connections?

The three primary types are KF/QF (quick flange) for medium vacuum, ISO (large flange) for high vacuum systems, and CF (ConFlat) for ultra-high vacuum applications requiring metal gasket seals.

How do you ensure vacuum integrity at port connections?

Vacuum integrity is maintained through precision-machined sealing surfaces, proper gasket selection (elastomeric or metal), controlled bolt torque patterns, and helium leak testing to verify leak rates below specified thresholds.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
