Take a minute to watch this unsolicited video review of our weatherproof extension cord gaskets, by Youtuber Christmas on Crestline.


If you have outdoor pumps, fountains, or yard lights, the chances are, when it rains, your yard goes dark. That's because water seeps into the connection, causing a short that trips the GFCI outlet's protection switch. With Rain Block Extension Cord Weatherproof Gaskets and Seasonal Lighting & Decor Weatherproof Kit, it can rain, it can pour and your yard will stay beautiful.

Connect them to yard lights, Christmas lights, pumps, generators and more. The soft rubber compound keeps the rain and water out of your electrical cord and extension cord connections to keep the power flowing.

I tried all sorts of solutions because I live in rainy Ohio where around Halloween and Christmas it is miserable and awful to try to keep halloween or Christmas decor on. I tried pin pointing the problem, I tried different extension cords, I tried electrical tape and lo and behold the simplest solution was also the best. These things are on all of my extension cords at the site where they plug into the decoration or light strand and I have had no power cutoffs even with torrential rain. Most of the streets decor goes off but mine keep on ticking. Just a fantastic product. I know the price seems a bit too much but to not have to hassle anymore with GFCI tripping Well worth it.

Ordered Another Pack So I Guess I'm Satisfied!

These seem to be the best priced, though admittedly I wish they were a little less expensive especially since they are not eligible for free shipping. I put up some colored LED lights in the yard for year round use and I feel better having the gaskets as well as the sealers for unused plugs. I ordered another pack for my Christmas lights. A couple years ago, water seepage through electric tape on a junction caused a strand of expensive lights to blow out. I had to buy new and go through the bother of taking down the broken ones and putting up a replacement. I'd rather spend a few bucks on the added protection these provide. To seal the ground hole on outlets that have it but are receiving a plug with just two blades, I simply turned a sealer around and used the stem portion in the empty hole. Kind of a waste of a full piece, though. Individual ground hole plugs would be nice.

I have yet to have a ground fault very good product

Expensive, but very good quality. Worked very well on my weather exposed christmas lights. The connections look like they're glued together once installed - no water infiltration. But they came back apart with no trouble and clean enough to reuse next year.
