Losing heat in your Pit Boss Pellet Grill? It may be time to consider beefing up the seal of your grill. So, let’s chat about how to seal up your pit boss pellet grill.

If you’re a new Pit Boss owner, you might have heard some people talking about sealing their grills. Your Pit Boss has a lid, so why would you need to seal it? 

Sealing the Pit Boss Pellet Grill is an important step in ensuring that your grill functions properly and lasts for a long time.

By applying a thin coat of high-temperature silicone sealant to the gasket on the lid and around the edge of the door, you can create a watertight seal that will keep moisture out.

Make sure to allow the sealant to dry completely before using your grill. 


What Is a Pellet Grill?

A pellet grill is a type of barbecue grill that uses wood pellets as fuel. The pellets are made from compressed sawdust, which is then ignited using a hot rod.

The grill heats up quickly, and the wood pellets provide intense heat and flavor for perfect grilling every time.

Are Pellet Grills Worth It If You Have To Seal It?

There are a number of reasons why you should consider buying a pellet grill.

First, pellet grills are incredibly easy to use — all you have to do is load the pellets into the hopper, ignite the grill, and set the temperature.

There’s no need to fiddle with any complicated controls, and you can cook food just like you would on a traditional gas or charcoal grill. 

The benefits of the Pit Boss Pellet Grill are numerous. First and foremost, pellet grills are incredibly easy to use.

Pellet grills also produce less smoke than traditional grills, so they’re perfect for those who want to enjoy great grilled flavor without having to deal with the mess and hassle of traditional smoking methods.

Finally, pellet grills are incredibly versatile — they can be used for everything from slow-cooking ribs to searing steaks. 

Why You Should Seal Your Pellet Grill

Pellet grills typically produce less heat than their traditional counterparts though. They’re designed to cook food “low and slow.”

So if there’s any opening in the grill itself, you’re going to lose that precious heat quickly.

Sealing your pellet grill helps to keep this heat in where it belongs. 

When storing your pellet grill, it’s essential to keep moisture out of it. If any moisture reaches the burn pot, you’re going to have problems the next time you try to fire it up.

So sealing it can also save you headaches on your future grilling sessions. 

How To Seal Your Pellet Grill

If you have a Pit Boss Pellet Grill, then it’s important to seal it properly to ensure that the heat stays inside, the pellets stay lit, and moisture stays out.

You can do this by applying a thin coat of high-temperature caulk, ceramic clay, silicone sealant, or fire or stove rope to the edge of the lid, and around the edge of the door.

Make sure to allow the sealant to dry completely before using your grill.

Sealing with Silicone

Silicone is heat resistant, so it makes for a great sealant on your pellet grill. It’s also easy to apply with a caulk gun, and you can get it at your local hardware store. 

Wash the lid of your grill with soap and water, then allow it to dry completely.

Take a pencil or marker and mark any gaps between the top and bottom sections of your smoker that might need sealing.

These areas will be used as guides for applying the silicone later on.

Remove all ash from inside of the grill using an ash tool, by removing the grease tray, or with a vacuum cleaner hose attachment (less common).

Simply apply the silicone sealant to the marked areas, and allow it to dry. Close the lid and check for openings again, and make adjustments if needed. 

Sealing with Fire Rope

Fire or stove rope is another great way to seal your Pit Boss pellet grill.

It can be found at your local hardware store, and is very easy to apply with high temperature adhesive. The great thing about this stuff is that it’s highly resistant to heat and moisture.

Simply cut the fire or stove rope roughly where you want it to go on your grill — make sure there is enough extra for wrapping around the lid and door — then use a lighter or match to melt each end until it’s fused together, forming a seal.

Make sure you’ve got enough rope down so that when the lid closes flush, everything lines up properly.

Once you’re done sealing your grill with fire rope, simply allow it to dry completely before using.

Sealing with High-Temp Caulk

Caulk makes for another great way to seal your Pit Boss pellet grill.

You can pick up a tube of high temperature caulk at your local hardware store, and it’s easy to apply with just about any caulk gun. 

Sealing with Ceramic Clay

Ceramic clay is another commonly used method of sealing smokers, but it requires much more time and attention to detail.

You can buy ceramic clay from a hardware or arts and crafts store, and it will be in the same area as fire rope.

Once you have the ceramic clay, use a roller to work it down into a malleable form, and then cut it into strips long enough to cover the parts of your lid that need sealing.

Applying strips to the lid of your grill along both edges will ensure that everything lines up properly when the lid is shut, and that no smoke can escape. 

Sealing with Aluminum Foil

Although it’s not a permanent solution, it can save the day in a tight spot. Simply take bits of aluminum foil and fill in the gaps where smoke is coming out. It’s not the best solution, but it will work once!


So, now you know how to seal your pellet grill.

Sealing the grill will help ensure that the heat stays in and the moisture doesn’t make its way into the interior of the grill, making your food soggy or damaging the electronics.
