Koenig Expanders®
A reliable solution for high-pressure applications
Koenig Expanders® provide an efficient solution for sealing drilled holes, particularly in high-pressure applications such as hydraulic and pneumatic systems.
These components consist of a metal sleeve that expands when a ball is pressed in, creating a secure and leak-proof seal, even in the most demanding environments.
Effective and versatile sealing solution for high pressure
During installation, Koenig Expanders® create a strong metal-to-metal seal that can withstand operating pressures of up to 500 bar, making them a reliable solution for high-pressure applications. They are widely used to securely seal manufacturing-related bores, particularly in fluid technology and hydraulic systems.
This type of seal is popular in industries such as automotive manufacturing and hydraulics, where they are often used to seal auxiliary bores in components like ABS brake systems, fuel injection systems, and suspension systems. Their versatility also makes them ideal for use in cast metal parts, where post-machined holes can be sealed quickly and efficiently.
Koenig Expanders® are available in a wide range of sizes and types that can be adapted to specific pressure load requirements and installation methods, whether installation is done by pulling or pressing. The type can be selected to match requirements for production efficiency and load specifications.

How can we help you?
Metal seals for challenging conditions
Our metal seals and technical components are designed for environments where elastomers and thermoplastics fall short. With the ability to withstand exceptionally high pressures and temperatures, metal seals are ideal for demanding applications.
Their superior chemical resistance and durability ensure reliable performance in harsh conditions, while the minimal risk of leakage makes them the preferred choice when safety and efficiency are essential.
