KF 4-Way Reducing Cross

The KF 4-Way Reducing Cross provides a compact and reliable solution for connecting four vacuum lines with different nominal flange sizes. Its cross-shaped design features four ISO-KF flange connections arranged at 90° angles, allowing efficient distribution and integration of vacuum components within a single assembly.

Manufactured from high-quality stainless steel or aluminium, the reducing cross offers a robust construction for vacuum and high-vacuum applications. The combination of different flange diameters makes it particularly useful for connecting smaller vacuum lines, instruments, or auxiliary components to larger vacuum systems without additional reducing adapters.

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 Size Combinations: DN25/16, DN40/16, DN40/25, DN50/16, DN50/25, DN50/40 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 reducing flange connections

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 with different nominal diameters.

The reducing cross is particularly useful for integrating vacuum gauges, pumping lines, valves, and auxiliary components into compact vacuum assemblies.

Installation and Compatibility

Compatible with standard ISO-KF flange connections of the corresponding nominal sizes. 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.

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