Product Overview & Description

EC28-208-EM by Elasto Proxy on Sketchfab

EC28-208-EM is an EPDM bulb trim that provides environmental sealing for doors and hatches with rounded corners. The bulb fills the gap and compresses to form a seal when the door or hatch is closed. When the door or hatch is open and the compressive force is removed, the sponge rubber bulb returns to its original dimensions. The trim, or retainer section, is made of solid rubber and attaches to the substrate.
