These neoprene foam cords stand up to water, sunlight, and oxidation, plus they resist swelling when they come into contact with oil. Use them to seal and cushion narrow spaces, such as channels. This foam has closed-cell construction, which restricts water, air, and gases from being absorbed. Cords have a smooth texture for a sleek surface that's easy to wipe down.
