Product Description

Product Description

KF Baided Flexible Hoses/Bellows Vacuum Bellows Connection, KF25 (NW 25), Stainless Steel Bellow

We fabricate these KF Braided Flexible Hoses - Vacuum Bellows from stainless steel 304 braided hose, use in KF (QF) flange to a particular type of port or tubulation. They offer great flexibility in the design and construction of high vacuum system environment.
The braided flexible hose consists of a relatively thin wall formed stainless steel bellows with a stainless steel braided sheath. The flexible stainless steel braiding protects the formed bellows from abrasion or impact produced by component movement or vacuum cycling and also protects the hose from excessive bending. The flexible stainless steel hose are used for foreline vacuum plumbing and for simple high vacuum(HV) chamber ports. KAYSEN vacuum braided flexible hose are the vacuum industry standard for ultra-high vacuum applications.
We have other Sanitary Fittings, such as Din Sanitary Fittings, SMS/DS Sanitary Fittings, Sanitary Clamps, Sanitary Ferrule & Adapters, 3A Sanitary Fittings. If you like, pls contact me for details.
