Co-Extruded Rubber Flap Seals

What are Co-Extruded Trim Seals?

Co-extruded trim seals fuse together a dense or rigid material to create a strong attachment and a reliable seal. Their soft, flexible material combines a PVC trim, an EPDM sponge rubber flap, an integrated aluminum metal clip and a strong gripping tongue.
