The TGU series give general characteristics that are suitable for piston application in double-acting cylinders. Composed of three elements: main sealing element in reinforced rubber fabric (our type FUCA 77), a NBR energizer that ensures that the sealing lips of the main element are working even in cases of low pressure, and to prevent extrusion, an acetal resin anti-extrusion ring in POM has been incorporated into the main element.
