DIMENSION TABLE
ED Ring · DIN 3869
Find the size by metric or BSP thread. Dimensions are stated in mm. When ordering, we recommend confirming the size and application against the existing seal or fitting.
Reference check required: the 2014 catalogue (page 195) gives different values for ED14 inner diameter and ED60 outer diameter than this dimension overview. Please confirm these two sizes against the fitting or an approved drawing before ordering.
Use the drawing together with the table below to identify the correct ED Seal.

Selecting an ED Seal: Provide the thread, existing ED reference or dimensions (ID, OD, T and T1). We confirm the correct size and material before production.
MATERIALS
Material according to the application.
ED Seals are available in materials including NBR and FKM. For more demanding chemical and temperature conditions, FFKM can be considered. Final material selection must be evaluated against media, temperature, pressure and operating conditions.
FFKM
HIGH PERFORMANCE
ED Seals in FFKM.
For demanding applications, ED Seals can be supplied in FFKM. The FFKM 70 documentation describes the material properties, while final suitability is evaluated against the ED geometry and actual operating conditions.
Send the size or drawing together with media, temperature and pressure. We evaluate the appropriate solution for the specific inquiry.
