Outdoor Weatherproof Extension Cord Gaskets and Plug Covers (combo packs)

Combo Pack Size: 5
Color: White


Our all weather outdoor plug covers combined with the use of plug gaskets allow you to protect open outdoor female plug ends. Fits 2 and 3 prong female plug ends (found on most common outdoor extension cords and holiday light strings). And, if you need to only cover the single grounded plug opening of a female plug (such as where you have plugged a 2-prong male plug into a 3-prong female extension cord leaving an exposed ground) you can simply break off the 3rd prong cover tab to use for this scenario (see our product pictures to best visualize this scenario).

Use PlugShields plug gaskets along with our plug covers to block out rain and snow that gets into outdoor extension cord plug connections and holiday light string plugs, causing GFCIs to get tripped. Installs in seconds, can handle any type of weather and easily stores on the extension cord or light string plug for the next use.

Stop Tripping GFCIs

It’s a cold, rainy night and your outdoor holiday lights just went off. The GFCI was tripped. Don’t like having to hunt down which plug connections got water in them? We didn’t either. That's why we launched PlugShields All-Weather Plug Gaskets and All-Weather Plug Covers.

All-Weather Gaskets fit between your plug connections to keep rain and other elements from tripping your GFCIs. Our All-Weather Plug Covers fit on the end of any open-ended plug to block moisture from getting in. Using All-Weather Plug Gaskets and All-Weather Plug Covers will assist your GFCIs to keep your lights on, even with rain, sleet or snow. These soft, pliable shields can save you hours and hours of time and frustration when it matters most.

Weatherproof Gaskets and Weatherproof Plug Covers are not only good for Christmas lights but can save you time and money in a number of applications such as hydroponics, outdoor events, ponds, landscaping, construction sites, farms, plant nurseries, fisheries, ranches, breweries, parade floats, campgrounds and many more! Applications are only bound by your imagination.

For use on light strings that have both a male and female plug on the same end (such as Christmas lights), Plug Covers sit on top of a PlugShields gasket then both fit into the female end of the plug connection. Fits 2 or 3-prong plug connections. Simply break off the 3rd prong on the PLug Cover to use with 2 prong connections. Must be used with PlugShields all-weather plug gaskets.

How to Use

  1. Clean and dry all surfaces
  2. Place Weatherproof Gasket on Plug Cover
  3. Firmly push Cover into female plug
  4. Remove ground prong if plug does not have ground

Important Things to Note

  1. Weatherproof Gaskets and Plug Covers can be washed & re-used multiple times.
  2. Weatherproof Gaskets and Plug Covers can be used with both 2 and 3 pronged plugs.
  3. Even in very cold weather, Weatherproof Gaskets will remain soft and pliable.
  4. If you are still having problems with the GFCI tripping after using Weatherproof Gaskets and/or Plug Covers, double check you are using extension cords rated for outdoor use. Also make sure you aren’t overloading a single circuit. If your breaker trips, contact a licensed electrician.
  5. Don’t discard the third prong. You can break off the ground prong and use it with a gasket to seal off the open, female ground hole in the first strand of the series that you plugged
    into the extension cord.

Mansoor S. (Williamston, US)

Works as advertised, and perfect solution for my outdoor plugs to make them waterproof!

Robert W. (Lincoln, US)
Great Idea and the PlugShields were delivered quickly.

these are awesome...needed them for my Christmas lights setup work great for connecting the sections of lights and for terminating the connections with no risk of water intrusion. Is way easier then taping the line or using expensive plug covers.

Braden V. (Bradenton, US)
Didn't work as advertised.

Couldn't prevent lawn sprinklers from shorting the circuit.

Scott B. (Albuquerque, US)
Not water tight

Recent purchase for this year. Bought both the plastic plug and silicone gaskets. Had a good rain and my xmas display shorted out.

Tom E. (Richmond, US)
Ingenious Idea

They work great, wish I had thought of it!

Suitable for Many Outdoor Situations

PlugShields gaskets and plug covers are ideal for holiday lights (Halloween, Christmas), however PlugShields can be used wherever there is potential for moisture to get into extension cord plugs that could then disrupt your outdoor event or major outdoor work project. Please contact us if you have any unique case for which you do not see below.

Frequenty Asked Questions


The All-Weather Plug Cover is uniquely designed to easily break off the ground prong section for use on 2-pronged, female plugs. For the 3-pronged female plugs, no alteration to the All-Weather Plug Cover is required. Use as is. Make sure to use plug covers with our all-weather gaskets. Plug covers should not be used without a plug gasket.


Even when it is freezing outside with snow coming down, the waterproof material for the All-Weather Plug Gasket remains soft and pliable. This material can withstand extreme temperatures ranging from -65 to 450 degrees Fahrenheit.

This is quite simple and our products were designed to easily handle this frequent holiday scenario.  Simply break off the 3rd prong on the All-Weather Plug Cover to create a single pin for use to cover female ground hole. The All-Weather Plug Cover ground pin will fit through the gasket to seal the open hole. Always make sure to use our plug covers in combination with our plug gaskets.


The All-Weather Plug Gasket material was purposely designed to be extremely pliable and waterproof. The thickness is approximately 1/16 inch and does not interfere with the power requirements of the connection. When the plug is connected, the All-Weather Plug Gasket will compress between the male and female plugs allowing the mechanical friction of the connection to hold the shield securely in place.

For loose-fitting plugs, it is recommended that you increase the friction of the connection by slightly pulling apart the two male prongs.


The All-Weather Plug Gasket and Plug Covers have been used by other customers for many year. You can simply store them by leaving them on your disconnected male plugs or leave the plug covers with gaskets inserted into the female plug for storage. If they get muddy or dirty, we do recommend that you rinse the gaskets with water as and they will easily clean up for repeated use.

The All-Weather Plug Cover is a male plug and should always be used in conjunction with an All Weather Gasket to terminate the open female end of the power source. If you do not terminate the open female plug end, it is likely that your GFCI will get tripped.


It is not recommended to use the shields on a wall plate plug because wall plates tend to have indentions. They are not flat, therefore we cannot guarantee you will get an effective seal. If you are having trouble with water getting into your wall plate plugs, we recommend using an outdoor weatherproofing outlet cover. You can purchase them at any hardware store.

First, double-check all of your plug connections. Make sure you have a tight seal.

Second, make sure any light strands, extension cords, or other connections you are using are rated for OUTDOOR use. Power cords that are rated for indoor use are not waterproof. Any moisture will cause an indoor power cord or indoor light strands to trip a GFCI.

Third, make sure you are not plugging too many things into the same circuit going above the amperage rating. If you are tripping a breaker and not just the GFCI, you may have too much current being drawn on a single circuit. If you are having problems with your breakers tripping, we recommend that you try using a different outlet that is not on the same “problem” breaker circuit. If you have re-routed your power cords to a different circuit and you are still tripping breakers, we highly recommend you contact a licensed electrician to help you figure out what and where the problem is.
