Side Bubble Gaskets with Steel Core are also known as bulb trim seals because of the round shape at the top of the trim. We have the expertise to co-extrude double bulbs, add butyl to the trim, add slip coating, and use multiple materials and densities. Side Bubble Gaskets with Steel Core come in various materials which include but not limited to: Dense and Sponge EPDM, Neoprene, vinyl and PVC. Side Bubble Gaskets with Steel Core typically have reinforced carriers using a flexible wire core or flexible segmented steel core. These rubber seals are placed on the window, door or truck body to allow for water and weather resistance.
