    BUNA-N Tri-Clamp Gaskets Buna-N Tri-Clamp gaskets are the preferred choice of material when using a closed loop, closed column, or open blast extraction when butane or propane are used as the extraction solvent. Buna-N Gaskets offer a lower temperature rating and have better physical properties than Viton gaskets; the best part is that they cost less than Viton and provide the same chemical resistance to butane and propane.
