4.3/10 Dust Cap with IP67 Seal
The Amphenol RF 431-10001 is a protective cap (cover) for 4.3/10 interface jacks. It is designed to seal the connector interface when unmated, with an IP67 rating that keeps out dust and moisture — critical for outdoor antenna ports, base station jumpers, and any RF link exposed to weather. The cap includes a captive chain so it stays tethered to the cable or panel, preventing loss during field service. The silver colour is the natural appearance of the nickel plating.
IP67 and Chain — Field-Ready Details
The chain is a practical feature for tower crews and installers: the cap stays attached to the cable assembly, so it is always available when the connector needs to be covered.
