Product Description
Type N Male to Type N Female Coaxial Connector Saver
Product Description
Protect valuable RF equipment with the G337-SAV - Type N Male to Type N Female Connector Saver from American Radio Supply. Designed to serve as a sacrificial interface between frequently connected coaxial cables and equipment ports, this straight-through adapter helps reduce wear on expensive RF connectors caused by repeated mating and disconnection.
Featuring a durable nickel-plated brass body, a Delrin dielectric, and gold-plated beryllium copper contacts, the G337-SAV provides a robust mechanical connection for 50-ohm RF systems. Its threaded Type N interface offers secure coupling for compatible radios, antenna systems, wireless equipment, and RF test setups.
Install the connector saver on a frequently accessed equipment port and connect compatible cables to the adapter. Replacing a worn connector saver is generally simpler and less costly than repairing or replacing a damaged equipment connector.

Installation Notes
-
Confirm that the equipment port and mating cable use compatible 50-ohm Type N interfaces.
-
Thread the connector saver onto the equipment port carefully, avoiding cross-threading.
-
Secure the connection according to the equipment manufacturer's recommended coupling procedure.
-
Inspect the adapter periodically for worn threads, damaged contacts, or other signs of deterioration.
Important: The connector saver is intended to reduce mechanical wear; it does not eliminate connector wear or guarantee protection against damage. The specified 12 GHz frequency range and typical VSWR should be verified against the requirements of the intended RF system. Weatherproofing and environmental sealing are not specified for this model.
