Below 1 PPM Testing

One of the most important elements of our reliability is consistency. Our sealing and flow control products and quality control processes are engineered to consistently deliver failure rates less than 1 PPM. This commitment perfectly expresses how we support our industry partners to optimize their manufacturing operations, so our expander plug, flow control orifice and check valve products consistently perform at the required quality levels. The result: higher-value products and improved profitability.


As the world leader in sealing and flow control, we have used our decades of experience to develop a broad range of expander plug, flow control orifice and check valve products. We offer both standard and custom-designed solutions based around our KOENIG EXPANDER®KOENIG RESTRICTOR® and KOENIG CHECK VALVE® product lines.

All of our expander plug, flow control orifice and check valve solutions are designed to meet exact and unique quality standards.
