Custom Stainless Steel Vacuum Hoses and Couplings
Vacuum hoses and couplings connect or extend components within a UH or UHV system. Pfeiffer Vacuum Valves & Engineering's product line offers flexible hoses and couplings with flanged end terminations, including ISO-KF (NW), ISO-K, CF (Conflat), and ASA. We can fill high-volume orders of flexible hoses & couplings and have various types and lengths available. Our stainless steel couplings can be ordered without a braided protective payer and reinforced PVC plastic hose. These vacuum hoses dampen vibrations and allow quick and easy connections between misaligned points in the vacuum system. Hoses can have thin, medium, and thick walls with customization options available depending on your application.Flexible Hoses & Couplings Features
- 321 Stainless Steel formed bellows construction
- Custom designs possible – just ask us.
- Many different hose & coupling lengths and diameters

ISO-KF (NW) Hoses and Couplings
We offer ISO-KF Thin Wall Flexible Hose, ISO-KF Medium Wall Flexible Hose and ISO-KF Braided Flexible Hose with varying wall thicknesses. Hose lengths range from 3.2” to 40” with custom lengths available. These are easy to install with ISO-KF wing nut clamp, centering ring, and O-ring.ISO-K / ISO-F Hoses and Couplings
ISO-K / ISO-F hoses and couplings can be supplied with alternate materials and custom designs. ISO-K / ISO-F flexible hoses and couplings are available in flexible wall thickness or robust, thick wall depending on your application. These couplings are simple to install with single or double-claw clamps.ConFlat (CF) Hoses and Couplings
ConFlat hoses and couplings are compatible with a DN 16 CF (1.33” OD) flange. Vacuum hoses are constructed from 321 stainless steel, while the flange and cuff constructed from 304 stainless steel.ASA Hoses and Couplings
We supply ASA hoses and couplings with wall thicknesses from 0.006" to 0.016" and 14” free lengths. Available in flat-flat or groove-flat configurations.PVC Hoses and Couplings
Our ASME certified 0.5” ID PVC flexible hose dampens out pump vibrations with a flex coupling. Standard lengths and flange combinations are offered, with others available. PVC flexible hose is sold by the foot and can be ordered with part number PVC-050.Flexible Hoses and Couplings Features
The specific benefits of our hoses and couplings vary depending on the specific type of hose and coupling. General features of Pfeiffer Vacuum Valves & Engineering's hoses and couplings include:- 321 stainless steel construction
- Custom designs available upon request
- Hose and coupling lengths and diameters
- Easy to install
- ISO 9001:2015 certified
Flexible Hoses and Coupling for Medium, High, and Ultra-High Vacuum Applications
We manufacture custom and standard vacuum hoses and couplings for medium, high, and ultra-high vacuum applications. The capabilities of each hose and coupling vary based on the design and materials used. While we are always looking to expand our capabilities, frequent applications for our vacuum hoses and couplings include:- Semiconductor industry
