Tertullus RCA CAPS-01 24K gold RCA dust caps 🎧
Description:
This set of protective caps keeps unused RCA sockets free from dust and oxidation while helping to reduce background hiss, ideal when maintaining a home audio rack or studio patchbay. These RCA dust caps fit most standard RCA female jacks and aim to maintain clearer signal paths by protecting exposed connectors.
Key Points
Slip these caps over open phono inputs to protect against dust and the early signs of oxidation, which can degrade signal quality over time. The caps include internal clamping springs that secure them to the socket, reducing the chance of accidental loss during maintenance or cable changes 🎧. According to the manufacturer, users may notice a lower noise floor and improved clarity when open inputs are covered, especially with older or sensitive analogue equipment.
Use them on the rear of amplifiers, turntables, DACs and AV receivers to keep contact surfaces clean. They are small and unobtrusive so multiple units can be placed across a rack without affecting cable routing. Consider that very deep or unusually shaped RCA sockets found on some professional hardware may require a different protective solution.
Benefits
These caps are finished to limit oxidation and preserve contact surfaces, which helps the overall texture and microdynamics of analogue reproduction. The combination of protection and a tight fit means less maintenance and fewer intermittent connections over months and years. They are light in weight and easy to install, allowing quick removal when you need to connect a lead. The metallic finish also gives a tidy, uniform look to any panel, keeping the rear of equipment visually organised 🛡️.

Usage Recommendations
Fit the caps by gently pressing them onto the RCA socket until the spring action engages. Avoid forcing caps onto connectors that feel very tight, since excessive pressure can damage delicate sockets. If your system is primarily digital with balanced connections, these caps will still protect any spare RCA inputs and help keep the installation neat. For best results, inspect the contacts periodically and replace caps that show signs of wear or severe tarnish, as their protective effectiveness may decline over long periods according to the manufacturer.
