The Multi-Contact 32.0716 PV-BVK4 is a rubber sealing cap MC4 female connectors. It plugs into the end to form a weather-proof seal for exposed connectors. Great for covering up unused inputs on micro-inverters and such! The corresponding type for male connectors, PV-SVK4, is available as well. This cap is identical to the one sold by APsystems under the name “MC4 Caps” or APS-MC4-PLUG-F, just much cheaper. APsystems buys these from Multi-Contact.
