Gaskets are designed for mating ground flange surfaces on reactor flasks and matching heads.

FETFE, an exclusive ACE product made from TFE impregnated fluoroelastomers, features a leak-free seal with clamp pressure and good chemical and temperature resistance. PTFE provides excellent chemical resistance and purity. The FETFE gaskets offer a thickness of 0.5 mm (0.02"), while the PTFE gaskets offer a thickness of 0.8 mm (0.03").

They can be used with all conical-style and flat flange-style flasks and heads. All gaskets feature grooves, with the exception of item 89055-004, which is designed without grooves. Available in either black FETFE or white PTFE.
