Ten black silicone caps protect unused RJ45 ports from dust and oxidation

  • Protects RJ45 ports from dust and debris
  • Silicone caps prevent oxidation on contact points
  • Easy push-fit design for quick installation and removal
  • Fits all standard RJ45 female Ethernet jacks
  • Pack of 10 black covers measuring 12 x 10 x 7mm

RJ45 Port Protection

This set includes ten black silicone caps that slip over unused RJ45 female jacks. They keep dust and debris out of the port and stop the contact points from oxidising. The plugs are simple to fit and remove whenever the port is needed again. Each cap measures 12 x 10 x 7 mm.

Thermals Noise Power

As passive silicone plugs they generate no heat, make no sound and draw no power. They do not affect the thermal or acoustic profile of the system in any way. Their only function is physical protection of the connector.

Build Integration

The caps fit any standard RJ45 female jack on motherboards, network cards, switches or patch panels. They free the builder from worrying about contaminated ports during assembly or storage. No tools or additional hardware are required for installation.

Questions about this item

How do I install the 12mm silicone caps on an RJ45 female jack, and what step do people often miss?

Press each cap straight onto the port until the 10mm width seats fully; the step often missed is checking that the .28in height sits flush so dust cannot enter the sides.

What maintenance or replacement will the 10 black silicone covers need over time?

Silicone can dry out or tear after repeated removal; replace any cap that no longer grips the RJ45 female jack tightly or shows cracks around the .5in length.

What limit appears first when the caps stay on a port continuously in a warm rack?

Prolonged heat can soften the silicone, reducing the friction hold on the RJ45 female jack before the material itself degrades.
