RCA caps protect RCAs from oxidation and signal interference such as RF, RFI, EMI emissions.
The rca shorting plugs are made of brass and gold-plated with a layer of Teflon in the protective cap, which is non-stick, abrasion-resistant, corrosion-resistant, and also helps to stabilise signal transmission and eliminate .
They avoid dust and dirt on the RCA sockets and prevent the sockets from rusting to maintain optimum conductivity.
The standard sizes of rca shield caps are perfect for most speakers, amplifiers, audio equipment, turntables, CD DVD players, DACs and more.
