KF Elbow 90°

The KF Elbow 90° provides a compact and reliable solution for changing the direction of vacuum piping by 90°. Its right-angle design features two standard ISO-KF flange connections, allowing vacuum components and piping to be connected along two perpendicular axes.

Manufactured from high-quality stainless steel or aluminium, the elbow offers robust construction for vacuum and high-vacuum applications. Its compact design makes it particularly suitable for vacuum systems where space is limited or where piping needs to be routed around other components.

Available in stainless steel 1.4301 (AISI 304), 1.4404 (AISI 316L), and aluminium 3.2315 (EN AW-6082), providing material options for different vacuum system requirements.

Technical Specifications

Flange Sizes: DN16, DN25, DN40, DN50 KF

Materials: Stainless Steel 1.4301 (AISI 304), Stainless Steel 1.4404 (AISI 316L), Aluminium 3.2315 (EN AW-6082)

Flange Connection: ISO-KF (QF / NW)

Configuration: 90° elbow with two KF flange connections

Bend Angle: 90°

Sealing: Compatible KF centring rings with elastomer O-ring seals

Applications

Suitable for vacuum chambers, pumping systems, vacuum manifolds, laboratory vacuum equipment, and industrial vacuum installations requiring right-angle piping connections.

The 90° elbow is particularly useful for changing the direction of vacuum lines, connecting components positioned at right angles, and creating compact vacuum piping arrangements.

Installation and Compatibility

Compatible with standard ISO-KF flange connections of the corresponding nominal size. Each connection requires a suitable KF centring ring with O-ring seal and a KF clamp.

Compatible KF Centring Rings & Seals and KF Clamps are available separately.

For applications requiring a less abrupt change in direction, the KF Elbow 45° is also available.

The achievable vacuum pressure and operating temperature depend on the selected sealing components and operating conditions.
