KF 4-Way Cross

The KF 4-Way Cross provides a compact and reliable solution for connecting four vacuum lines within a single vacuum assembly. Its cross-shaped design features four ISO-KF flange connections arranged at 90° angles, allowing vacuum components to be connected along two perpendicular axes.

Manufactured from high-quality stainless steel or aluminium, the four-way cross offers robust construction for vacuum and high-vacuum applications. Its symmetrical design makes it particularly suitable for vacuum manifolds, pumping systems, and experimental setups requiring multiple connections within a compact arrangement.

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: 4-way cross with four flange connections arranged along two perpendicular axes

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 multiple connections.

The four-way cross is particularly useful for integrating vacuum gauges, valves, pumping lines, and auxiliary vacuum components into laboratory and industrial vacuum assemblies.

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 additional connections, the KF 6-Way Cross is also available. For connections with different nominal diameters, consider the KF 4-Way Reducing Cross.

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