KF Reducing Tee

The KF Reducing Tee provides a compact and reliable solution for connecting three vacuum lines with different nominal flange sizes. Its T-shaped design features three ISO-KF flange connections, allowing a smaller vacuum line or component to be integrated into a larger vacuum system without requiring a separate reducing adapter.

Manufactured from high-quality stainless steel or aluminium, the reducing tee offers robust construction and reliable performance in vacuum and high-vacuum applications. The different flange diameters provide flexibility when connecting vacuum pumps, gauges, valves, and auxiliary equipment.

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.

Applications

Suitable for vacuum chambers, vacuum manifolds, pumping systems, laboratory vacuum equipment, and industrial vacuum installations requiring three-way connections with different nominal diameters.

The reducing tee is particularly useful for integrating vacuum gauges, pumping lines, valves, and auxiliary components into existing vacuum systems while minimising the need for additional adapters.

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.
