KF PVC Hose with internal reinforcing spiral

The KF PVC Hose provides a flexible connection between vacuum components, pumps, and vacuum systems. Manufactured from PVC with an internal reinforcing spiral, the hose combines flexibility with mechanical support to help resist collapse under vacuum conditions.

The integrated reinforcing spiral helps maintain the hose cross-section during operation, while the flexible construction allows convenient installation where rigid vacuum piping is impractical.

Equipped with standard ISO-KF (QF / NW) flange connections, the hose can be integrated into compatible vacuum systems using conventional KF centring rings, O-ring seals, and clamps.

Technical Specifications

Flange Sizes: DN16, DN25, DN40, DN50 KF

Available Lengths: 500 mm, 1000 mm, 2000 mm

Hose Material: PVC (Polyvinyl Chloride)

Reinforcement: Internal reinforcing spiral

Flange Connection: ISO-KF (QF / NW)

Design: Flexible vacuum hose

Applications

Suitable for connecting vacuum pumps, vacuum chambers, vacuum manifolds, and laboratory vacuum equipment where flexible connections are required.

The reinforced PVC construction is particularly useful for rough-vacuum applications and vacuum pumping lines where easy installation, flexible routing, and mechanical stability are important.

Installation and Compatibility

Compatible with standard ISO-KF flange connections of the corresponding nominal size. Suitable KF centring rings with O-ring seals and KF clamps are required for installation.

For high-vacuum applications requiring low outgassing and reduced gas permeation, stainless steel flexible hoses or metal bellows are generally recommended instead.
