KF vs CF Flange: A Complete Guide for High Vacuum and UHV Systems When assembling vacuum pipelines, choosing between KF and CF flanges is a fundamental decision for every engineer. These two most popular vacuum flange standards serve different vacuum ranges, operating temperatures and application scenarios. Understanding their differences helps you pick the right combination […]
Selecting the proper seal is one of the most important decisions when building high and ultra‑high vacuum systems. Two dominant options are the copper gasket and the Viton O‑ring, and each fits distinct vacuum levels, temperature ranges and process conditions. Mixing them up can lead to leaks, excessive outgassing or premature seal failure. A copper […]

Product Features Standardized and modular design, easy to replace and repair;Design for easy cleaning;The solenoid valve adopts energy-saving design and small size.Main performance index Scope of applicationPressure difference on valve plate when opening: ≤1.2 × 105Pa in […]
Various expected load values acting on metal bellows and other elastic elements, such as concentrated force F, pressure p and moment M, etc. When the metal bellows-type elastic element is used, in addition to the given load value, the direction and location of the load must be given. For compressive loads, it should also be […]
Threaded vacuum joint refers to the connector of the pipe with thread. It is a common pipe fitting in industry and daily life. Threaded vacuum joint makes the connection of the pipe simple and easy to disassemble and replace. Threaded vacuum joint The main features of threaded vacuum joints: Size range: 1/8 to 1 inch;Wide […]
A copper gasket is the standard metal seal for CF flanges, widely trusted in ultra-high vacuum systems where elastomer O-rings cannot survive high baking temperatures or meet strict low-outgassing requirements. Made from oxygen-free high-conductivity copper, this soft metal gasket forms a permanent hermetic seal when the knife-edge of a CF flange cuts slightly into its […]
When sourcing vacuum bellows for high vacuum and ultra-high vacuum applications, engineers often face a core choice: edge-welded vacuum bellows or formed vacuum bellows. Both types serve as flexible hermetic connectors to absorb vibration, thermal expansion and installation misalignment, but their manufacturing processes, mechanical limits, cleanliness and cost profiles differ greatly. Picking the wrong vacuum […]
The Introduction of Bellows The corrugated tube refers to a tubular elastic sensitive element connected by a foldable wrinkle sheet in a folding and stretching direction. Bellows are widely used in instrumentation. The main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The […]
Vacuum bellows are the flexible sealing backbone of high vacuum and ultra-high vacuum systems. Even premium-grade vacuum bellows may develop performance issues without proper handling, installation or routine inspection. Understanding typical vacuum bellows failure modes, root causes and troubleshooting steps helps engineers reduce unexpected leaks, avoid system downtime and extend the service life of vacuum […]
