The Jointed O-rings are practically the same as the Conductive O-profiles, however this is a turnkey closed O-ring. They are used where environmental and EMI screening is required but where little space is available.

These cores can be covered with metallized fabric foils or made out of conductive rubber. For optimal shielding performance a compression of 5-10% is recommended for solid elastomers and 10-50% for hollow extrusions and cell rubbers.
