RF Connector Dust Caps

RF (radio frequency) connector dust caps are used to protect the ends of RF connectors, a type of electrical connector that's designed to work at radio frequencies. The dust caps help prevent dust particles from getting inside the connector.

Features of RF connector dust caps and how they work

RF connector dust caps are very simple to use. They simply screw on to your connector. The body material is usually made from stainless steel or brass, and the plating material can be nickel or stainless steel for a strong, durable and hard wearing device.
