Product Description
CF Conical Reducer
A CF conical reducing adapter is used in vacuum systems to facilitate the transition between two ConFlat (CF) flanges of different diameters. In vacuum technology, CF flanges are known for their high vacuum performance and leak-tight connections, making them widely used in demanding applications. The conical reducing adapter is specifically designed to enable the seamless connection of CF flanges with varying sizes, allowing for flexibility in system configuration and component integration.
a CF conical reducing adapter plays a vital role in accommodating the transition between CF flanges of different sizes within a vacuum system. Its design and functionality contribute to the flexibility, adaptability, and vacuum performance of the system, allowing for seamless integration of components with varying CF flange diameters.

-Size Transition:
The conical reducing adapter is designed with a tapered or conical shape, allowing it to smoothly transition from a larger CF flange size to a smaller CF flange size, or vice versa. This enables the connection of components with different diameter CF flanges within the vacuum system.
-Vacuum Integrity:
The adapter is engineered to maintain the high vacuum integrity characteristic of CF flange connections, ensuring that the reduction in diameter does not compromise the overall vacuum performance of the system.
-Material and Construction:
CF conical reducing adapters are typically constructed from high-quality stainless steel or other materials compatible with vacuum applications. The robust construction ensures durability and longevity under vacuum conditions.
The design of the adapter allows for straightforward installation and removal, providing ease of use and flexibility for modifying the vacuum system setup as needed.
Conical reducing adapters are versatile components that can be used in various vacuum setups, such as connecting vacuum chambers, pumps, valves, and other CF flanged components with different diameters.
When properly installed, the conical reducing adapter forms a reliable, leak-free seal between the mating CF flanges, maintaining the integrity of the vacuum system.
