Frost King Outdoor Faucet Cover Review (FC1): Protect Your Spigots Before the First Freeze

As an Amazon Associate I earn from qualifying purchases.

If you’ve got outdoor spigots on your place, one hard freeze can split a hose bib and leave you with a leak hidden inside the wall. That’s a plumber bill nobody wants in January. The Frost King FC1 Outdoor Foam Faucet Cover is one of the cheapest, simplest winter prep jobs on the homestead: a foam cap that goes over a wall-mounted spigot in seconds. It comes as a two pack, and you can reuse it every winter.

What It Is

The FC1 is a grey, oval foam cover made by Frost King, a long-running weatherization brand from Thermwell Products. It fits over a typical wall-mounted outdoor faucet, also called a hose bib or spigot. The foam insulates the faucet and blocks freezing wind. Frost King also says it helps keep outside air from leaking into the house through the faucet opening, so it does a little draft duty too.

Each cover measures about 7 x 5.25 x 6.3 inches and weighs next to nothing. This listing gets you two covers, which is handy if you have a spigot on the house and another on the barn or shop.

Key Features

• 5/8-inch expanded polystyrene (EPS) foam shell that insulates the faucet and keeps wind off it
• 3/4-inch one-piece foam gasket that seals against your siding
• Synthetic rubber loop with a slide lock that holds the cover tight to the wall
• Arrives fully assembled, so you don’t need any tools
• Reusable season after season
• 2 pack of grey oval covers

How to Install (3 Steps)

First, do the basic winterizing. Disconnect your hoses, and if your faucets aren’t frost-free, shut them off and drain them from inside. Then:

1. Loop it. Put the rubber loop around the faucet handle.
2. Stretch it. Pull the cord away from the faucet, through the cover.
3. Lock it. Slide the lock until the cover sits firmly against the wall.

That’s it. It takes less than a minute per spigot.

Things to Know

• Bulky spigots may be a tight fit. The FC1 is sized for typical wall-mounted faucets. Some owners find it snug over bulky vacuum-breaker spigots, so check yours before winter hits. On textured siding, you may need a strip of foam tape to get a good seal.
• Not for yard hydrants. It’s made for faucets mounted on a wall. It won’t work on free-standing yard hydrants.
• Check the cord every year. The rubber cord can get brittle after a season or two. Look it over when you pull the covers off the shelf each fall.
• Foam vs. hard shell. Frost King says foam is the better pick for freeze protection. If knocks or curious animals are a problem where you live, they suggest their hard plastic cover (FC2) instead.

Who It’s For

This is for anyone with wall-mounted outdoor faucets who wants an easy, no-power way to winterize them. It’s cheap enough to put on every spigot you own: the house, barn, workshop, greenhouse, and well or pump house. If you like fixing things yourself before they turn into emergencies, this belongs in your fall checklist alongside cleaning gutters and stacking firewood.

It won’t replace good plumbing practice. You still want hoses off and non-frost-free lines drained. But as an extra layer of protection against wind and cold, it’s hard to beat for the money.

The Bottom Line

The Frost King FC1 is a simple, reusable foam faucet cover that takes seconds to install and helps protect your outdoor spigots from freezing wind and cold. Put one on every wall-mounted spigot before the first hard freeze, and you’ve knocked out one more winter prep job.
