Closed Cell Sponge Rubber Gaskets
Closed cell rubber, or expanded rubber, contains balloon-like cells filled with nitrogen gas, which block the flow of air, water, and chemicals at low pressures. Because of its consistent, solid structure, closed cell sponge rubber offers excellent sealing performance, providing resistance to acid, flame, and oil.
