Dust Cap N Male, with Chain

The 106-CAP-N1 is a protective cover for N Female RF connectors, designed to seal the centre socket and threaded interface against dust, moisture and physical damage when the connector is unmated. Its nickel-plated brass body houses a red elastomer ring that presses snugly into the 5/8–24 UNEF-2B thread, while the attached brass chain and retention loop clip back onto the connector housing to keep the cap in place during installation or service.

This accessory is ideal for telecom sites, laboratory test rigs and broadcast installations where clean, undisturbed RF contacts are essential. Field technicians and network engineers benefit from its simple fit-and-forget design, ensuring costly connectors remain contamination-free when stored or in transit.
