IFM E30438 is an EPDM O-ring designed for sealing compatible process sensor adapters and hygienic process connections. It has an internal diameter of 26 mm and an external diameter of 32 mm, giving a nominal cross-section of 3 mm. The O-ring is manufactured from EPDM with a 70 Shore hardness designation. EPDM is commonly used for applications involving water, steam and many aqueous process media. The compact sealing element provides a reliable interface between compatible process components. E30438 is supplied as one piece and is used with selected IFM process adapters and connections.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The EPDM material provides suitable sealing characteristics for compatible process applications. It can be advantageous where the process involves water-based media or other substances compatible with EPDM. The 70 Shore hardness provides an appropriate combination of flexibility and mechanical stability. The O-ring should be installed carefully to avoid cuts, twisting or deformation. Proper installation ensures that the sealing element remains correctly positioned during operation.
E30438 is designed around a 26 × 3 mm dimensional configuration for compatible IFM process adapters. It is used as a sealing element between process components where the specified groove and dimensions match. The correct O-ring material should be selected according to the process medium and operating temperature. IFM documentation lists E30438 as an EPDM alternative alongside E30437 FKM O-rings for compatible process adapters.
The O-ring weighs approximately 1.9 g, making it extremely lightweight and easy to handle during sensor installation or maintenance. Its 26 mm internal diameter and 32 mm external diameter provide the specified sealing geometry. The simple circular design allows quick replacement during service work. Because sealing performance depends strongly on surface condition and correct installation, the mating surfaces should be clean before fitting.
