LAMATEK Neoprene Sponge Gasket Tape SCE-43B

Lamatek Neoprene Sponge Gasket Tape SCE-43B is a closed cell blend of neoprene sponge, EPDM and synthetic rubber with a dense mass of tiny pores (or cells) to seal out air, moisture, liquid, gas, oil and more. Neoprene rubber tape is ideal for higher temperature applications where the seal isn’t frequently re-opened or broken. Lamatek’s neoprene rubber tape is available in several grades from soft to firm to absorb various weights and compression levels.
