CF63-CF35 six-way (stretching)

This product is a multi-channel chamber connector for ultra-high vacuum applications, manufactured via integral deep-drawing and precision machining from stainless steel. One end features a CF63 main flange, while the remaining ports are CF35 branch flanges, enabling single-inlet, multi-outlet vacuum pipeline distribution and expansion for the construction of UHV/HV vacuum systems.
Product Features:
1. Multi-channel Integrated Architecture
Six-port configuration: one CF63 main interface plus multiple CF35 branch interfaces, offering a compact footprint and enabling simultaneous connection of multiple vacuum components, including pumps, valves, gauges, observation windows, and sample chambers.
2. Stretch Forming / Complete Finishing
Manufactured using stainless steel through deep-drawing or integral turning and milling, these components feature uniform wall thickness, excellent rigidity, smooth internal flow passages, high flow conductivity, resistance to dust accumulation, and easy cleanability.
3. CF Knife-Edge Metal Seal
Standard configuration includes a CF flange with an oxygen-free copper gasket for metal-to-metal hard sealing, achieving an extremely low leak rate and making it suitable for ultra-high vacuum (UHV) environments.
4. High-temperature baking resistance, no outgassing or contamination
All-stainless-steel construction—no rubber, no plastic—enables high-temperature vacuum baking for outgassing, making it ideal for systems with stringent cleanliness requirements.
5. Strong versatility of standard interfaces
Both CF63 and CF35 are internationally standardized vacuum flanges that are directly interchangeable with various CF valves, blind flanges, fittings, and chambers.
6. Corrosion-resistant and long-lasting
Commonly used are 304 and 316L stainless steels, which offer excellent resistance to acids and alkalis, high-temperature tolerance, and outstanding oxidation resistance, making them suitable for long-term operation in vacuum or mildly corrosive environments.

Typical Applications
1. Ultra-High Vacuum Research Equipment
Molecular beam epitaxy (MBE), vacuum coating equipment, scanning tunneling microscopy (STM), and expansion of the physical experiment chamber.
2. Semiconductor and Thin-Film Equipment
PVD/CVD/ALD coating systems, ion etching equipment, vacuum piping distribution, and multi-point monitoring interfaces.
3. Analytical Instruments and Testing Equipment
Multi-channel vacuum interfaces for mass spectrometers, electron microscopes, leak detectors, and space environment simulation chambers.
4. Vacuum Platform for Universities and Research Institutes
Laboratory vacuum system setup, multi-station sample chambers, gas distribution systems, and sensor integration.
5. Optics and Laser Vacuum Systems
When used in conjunction with the observation window, laser input port, and spectral detection system, it enables multi-directional observation and access.
