Product Overview & Description

EC28-250-EM by Elasto Proxy on Sketchfab

EC28-250-EM is an EPDM bulb trim with a teardrop-shaped bulb atop a metal-reinforced retainer section. The bulb fills the gap and compresses when a door or hatch with rounded corners is closed. When the door or hatch is open, the sponge rubber bulb returns to its original size. The trim section is made of solid rubber and has interior tongues for gripping. This trim seal has RMA-E2 tolerance.
