Complete KF Vacuum Kit with Multiple Sizes：This set includes 1 KF Bellows Hose (available in KF25/KF40/KF50 models, 250mm/500mm/750mm/1000mm lengths), 2 aluminum clamps, and 2 KF centering rings—covers all parts for U.S. ultra-high vacuum system assembly, no extra purchases needed, with the KF Bellows Hose as the core connector.
Durable Core Components：The KF Bellows Hose is made of 304 stainless steel (heat and corrosion-resistant), paired with sturdy aluminum clamps and precision-machined KF centering rings. This combination ensures long service life in harsh U.S. industrial vacuum environments.
Leak-Proof & Oxidation-Free Performance：The KF Bellows Hose features seamless laser welding (no oxidation). When matched with dedicated KF centering rings and secured by aluminum clamps, every connection passes helium leak detection, fully complying with U.S. vacuum sealing standards.
Flexible & Easy Installation：The KF Bellows Hose (in 250-1000mm lengths) offers excellent stretchability and a flexible bending radius, adapting to complex layouts of U.S. vacuum systems. Aluminum clamps enable quick, tool-efficient installation, matching factory workflow needs.
Smooth & Low-Maintenance Design：The KF Bellows Hose has mirror-polished inner and outer walls, and KF centering rings have precise dimensions. Both are easy to clean, reducing daily maintenance time for U.S. vacuum system operators.
