Compared to other expander seal solutions, KOENIG EXPANDER® plugs consistently exceed performance expectations, providing a precise and reliable solution, often at the lowest cost when compared with competitors. These plugs feature a one-piece, easy-to-install design that integrates with automated manufacturing operations, and are available in a wide range of material options and plug sizes. KOENIG EXPANDER® components tolerate one of the widest temperatures ranges of any expander plug option in the market, with effective operation from -40°C to 150°C (-40°F to 302°F). Standard push-style and pull-style expander plugs can steadily work at pressures up to 450 and 550 bar respectively, and are pressure rated with safety factors to accommodate system shocks and pressure spikes.
