DURAN GUKO Rubber Gasket Conical 292021203

DURAN GUKO Rubber Gasket Conical 292021203

The Duran Guko Rubber Gasket Conical 292021203 ensures secure connections between funnels, filtering flasks, or crucibles. Its EPDM rubber composition delivers good flexibility, chemical resistance, and durability under repeated use. The gasket fits standard conical glass joints—on the wider side (~22 mm outer diameter) tapering to a narrower inner opening (~12 mm)—making it ideal for vacuum or gravity filtration systems. It tolerates autoclaving and typical lab temperatures, maintaining a reliable seal under moderate thermal stress.
