Bending Radius & Additional Information

EC28-420-EM is an EPDM trim seal with two different durometers, or hardness, on the Shore A scale. The trim or retainer is made of solid rubber and is harder to provide greater impact resistance. The bulb section is made of sponge rubber and is designed to compress when a closure force is applied. This trim seal is designed to resist compression set, the permanent deformation of a rubber seal after compression is removed.
