Vacuum Bellows & Flexible Hoses
KF/ISO and CF flexible vacuum hoses
KF/ISO and CF flexible vacuum hoses (bellows) are designed to provide reliable, leak-tight connections in systems where rigid pipework is impractical. They are ideal for applications requiring flexibility, vibration isolation, thermal expansion compensation, or where components must move independently whilst maintaining ultra-high vacuum integrity.
Manufactured in accordance with ISO and CF standards, our flexible bellows are fully compatible with industry-standard components from other suppliers, ensuring easy integration into new or existing vacuum systems.
Product Overview
UltraHighVacuum offers a comprehensive range of flexible vacuum bellows suited for a wide range of high vacuum (HV) and ultra-high vacuum (UHV) applications. Our standard range is available for next working day delivery, while our bespoke manufacturing service allows for custom lengths, diameters, and flange configurations tailored to your exact requirements.
Whether you are designing a new system or upgrading an existing one, our flexible hoses provide a dependable solution for maintaining vacuum performance without sacrificing mechanical flexibility.
Packaging & Handling
To maintain cleanliness and prevent contamination, all flexible vacuum hoses are supplied in sealed protective plastic packaging with protective end caps to safeguard flange sealing surfaces.
