IFM E30451 is an EPDM sealing ring designed for devices and process sensors with a G 1/2 process connection. It provides a reliable sealing interface between compatible threaded components and helps reduce leakage from the process connection. The gasket is manufactured from EPDM and is designed according to DIN EN ISO 1179-2. It supports an ambient temperature range from -40 to 130°C. The sealing ring has an inside diameter of 18.5 mm and an outside diameter of 23.9 mm. It is supplied in a pack of 10 pieces, making it suitable for installation, service and replacement requirements.

E30451 is designed to create a dependable seal between compatible G 1/2 process connections. When correctly installed, the sealing ring helps prevent process media from escaping through the threaded interface. Its EPDM construction provides the flexibility required to conform to the mating sealing surfaces. Correct positioning is important to ensure uniform contact around the connection. The gasket is suitable for use as an original replacement sealing component for compatible IFM process devices.
The sealing ring is manufactured from EPDM, a commonly used elastomer for industrial sealing applications. EPDM provides suitable resistance for many water-based and compatible process media. The specified ambient temperature range is -40 to 130°C. The material should always be checked for chemical compatibility with the process medium before use. Selecting the correct seal material is important for maintaining long-term sealing performance.
E30451 is designed for units with a G 1/2 process connection and follows DIN EN ISO 1179-2 requirements. The standardised configuration helps ensure compatibility with the intended sealing arrangement. Its 18.5 mm inside diameter and 23.9 mm outside diameter provide the specified sealing dimensions. Properly matching the gasket to the process connection helps avoid installation problems. It should not be substituted with an incorrectly sized sealing ring.
The product is supplied in a pack of 10 pieces, which is convenient for maintenance teams and repeated sensor installation work. Sealing rings are consumable components and may need replacement when a sensor is removed or serviced. The mating surfaces should be clean and free from scratches, dirt or old sealing material. A new gasket should be used when required rather than reusing a damaged or deformed seal. This helps maintain reliable process connection performance.
