The brass body gets a nickel finish that holds up to corrosion and maintains the RF ground path through the shell. A built-in chain feature lets you tether it to the cable or panel so it doesn't walk off during service. This cap fits standard TNC jacks — the threaded coupling rolls on by hand and seals the interface. It is not a universal cap for all TNC connectors; it is sized for the jack side, not the plug. If you are capping a TNC bulkhead receptacle or a panel-mount jack, this is the one. For a TNC plug, you need the matching plug cap. ## Material and Build Brass body with a nickel finish — the nickel layer resists the kind of surface corrosion you see on outdoor antenna ports or in industrial cabinets where humidity cycles. The chain is a simple stainless loop that clips onto a cable boot or a panel ring. Bulk packaging means you get a bag of them, not individual retail boxes.","metaTitle":"Amphenol RF 202101-11 TNC Cap Cover, Silver Nickel Brass","metaDescription":"Amphenol RF 202101-11 TNC cap cover, silver nickel-plated brass body, chain feature.
