A method for making an RF connector having an outer conductor and an inner conductor includes the steps of plating the outer conductor and the inner conductor of the RF connector with at least one corrosion-resistant metallic material; dispensing and/or injecting a material comprising an epoxy phenol novolac based resin. in a volume between the outer conductor and the inner conductor of the connector; heating the RF connector with the injected material to a temperature between about 150° C. to about 380° C. in a substantially dry nitrogen-based environment; and allowing the RF connector to cool.
