uxcell Ethernet Hub Port RJ45 Cover Cap Protector Connector 10Pcs Black

These represent an excellent solution for a very small problem. The rubber dust covers fit snugly into ethernet ports and Im quite comfortable they serve their purpose well (in this case protecting a switch installed into my garage workshop serving networked devices and some ethernet jacks connected through my attic). A tab allows for easy removal.

Exactly whats needed for keeping spare switch ports clean :)

These are perfectly suited for what I was looking for. I had initially ordered the harder plastic ones on Amazon, with the pull tabs on them. I wasnt very happy with those, and had to modify them to actually fit in one of my switches. I had not ordered these as I was hesitant as to how difficult they would be to remove. Once I ordered them, I realized how wrong I was. These are incredibly simple to remove from the port. Im keeping the other ones I ordered to use in a pinch. These will be my go-to port covers.

This are really great to put in RJ-45 ports to keep dust out. They are soft, easy to install, and remove. Have a device you just want to make sure you dont use the wrong port on? These are good for that too.

Will save much money & time later by preventing further corrosion in my switch.

not much to say, I use them to minimise dust ingress to electronic components since I am based in qatar.

I like that these work. I dont like that are harder to remove

Took a while to get them (shipped from China), but very satisfied with the product.

They plug the hole.

Bought 30, all fit perfectly. Would recommend them.
