IFM E30459 is a PEEK sealing ring designed for G 1/2 threaded process connections with a sealing cone. It provides a durable mechanical seal between compatible process sensors and process connections. The sealing element is manufactured from FDA-compliant PEEK material, making it suitable for applications where hygienic and material compatibility requirements are important. It has an inside diameter of 15.4 mm and an outside diameter of 18.8 mm, with an approximate weight of 5.4 g. The PEEK construction provides high durability and chemical resistance compared with many conventional elastomer seals. It is supplied as a single sealing element.

PEEK is a high-performance engineering polymer known for its mechanical strength and chemical resistance. E30459 uses PEEK to provide a durable seal for the specified G 1/2 connection arrangement. The material can be advantageous in applications where repeated cleaning or demanding process conditions are present. Unlike some elastomer seals, PEEK can maintain its mechanical characteristics over extended service conditions. The seal should still be used only within the limits of the complete process system.
The E30459 PEEK seal is FDA compliant and is intended for compatible hygienic process installations. IFM identifies the seal as being used with G 1/2 thread connections with a sealing cone. It provides a mechanical seal between the sensor and process medium. The design is particularly useful where cleanability and reliable sealing are important. This makes it suitable for selected food, beverage and hygienic process applications.
PEEK provides broad chemical resistance and can be useful where the process medium or cleaning chemicals may challenge conventional elastomer seals. IFM notes that the PEEK seal provides universal resistance to chemicals in the context of the PM15 installation. The material can also be more stable during cleaning processes where repeated sensor removal occurs. However, actual media compatibility should always be confirmed before installation.
E30459 is supplied as one individual seal and can be used as a replacement sealing component for compatible sensor installations. Its compact dimensions make it easy to handle during maintenance. The sealing surface should be clean before fitting, and the seal should be correctly positioned in the designated connection. Damaged or deformed sealing rings should be replaced rather than reused. Proper installation helps maintain process integrity and minimise leakage risks.
