Perfect for adding to my solar quick disconnect to keep it fully waterproof when not in use. Fit perfectly in the MC4 connections.

The MC4 connector covers were delivered quickly and fit snugly onto the MC4 connectors. I have not had them exposed to the elements yet, but they fit well and it seems they will hold up to the rain here in Florida.

It fit perfectly and survived a 2000-mile journey across the country without being lost along the way, with only a friction fit holding it in place. I recommend it if you are looking for something to protect your MC4 plugs.

I use these to protect the connectors on my portable solar panels and extension cables. I feel more confident about protecting the equipment I rely on while camping. They are easy to put on while packing up.

I like having these to keep the plugs clean on a single panel, mounted as a tiny solar backup panel since it is not always in use. Only needed one set, but the extras will be handy when we lose the first set ;)

Perfect for dust and short prevention. Relatively soft rubber(ish) material with ribbing that holds its shape well. Perfect density. I doubt they (or other similar brands) are waterproof…. but they’ll sure help. Just bought a second set to keep on hand. A must for your spare panels and great for cable storage as well. A simple, inexpensive product - really happy with them.
