TC Shielding has specifically developed the Duo-seal to offer a compact, space-efficient gasket. Comprising two different materials (a conductive and a non-conductive silicone or fluorosilicone), the Duo-seal can offer environmental, chemical and RFI protection in one easy to assemble solution. The Duo-seal is consistently used by our military and aerospace customers, on applications where high performance and environmental protection cannot be compromised.
