Gaskets are a crucial part of your stove's efficiency. They create an air-tight seal that allows for maximum, long burning fires. Diameters and styles vary, and they are commonly made of a non-asbestos material which poses no threat to the environment. Gaskets are held in place on your stove door with either high-temperature cement or adhesive backings, depending on the specific seal your model requires.

Due to the constant opening and closing of your stove door, it is inevitable that the seal will succumb to normal wear and start to show signs of needing replaced. This is a necessary task to avoid heat loss and emission of combustible gases. Replacing the gasket is fairly easy to perform, especially with our collection of superb products! Designed with easy application and stability in mind, you can expect a strong, long-lasting result from Fast Replacement Glass!

Why is it important to have a tight door seal?

A tight seal will ensure good air circulation within the stove or fireplace, as well as prevent smoke or gas leakage. Not only is it important to the proper functioning of your heating appliance, but also your health and safety!

What determines the need for door seal replacement?

It ultimately depends on how often the stove is used. If it is fired up on a daily basis, Fast Replacement Glass advises frequent inspections and replacement of the gasket the moment the door doesn't compress the seal as tightly as it should. Otherwise, the gasket on your stove door should be checked on a regular basis for other signs of wear, such as fraying and unraveling. (Depending on your stove's maufacturer, it may be recommended that you replace the gasket every 12 months, regardless of its condition. See your stove or fireplace owner's manual for guidelines.)

How can you tell if the door gasket is in good working status?

The seal should be tight! So tight, that a dollar bill inserted between the door and stove cannot be pulled out when the door is closed. Fast Replacement Glass highly suggests performing the following test on all sides of the door: 

  • Open your stove door and place a dollar bill between it and the stove body. Tightly close the door. 
  • The dollar bill should be firmly gripped by the gasket. Removing it should be difficult.
  • Repeat the test a few times, positioning the dollar bill at various locations around the door.
  • If the dollar bill is gripped tightly at all locales, this indicates a favorable seal. If any of the areas are weak, you'll definitely want to replace the gasket. 
Do I need to replace the window gasket if I have to replace the door gasket?

Window gaskets don't undergo the same compression forces as door gaskets do. That being said, the seal around the window glass doesn't need to be replaced nearly as often. However, if you notice any loose, fraying, or unraveling material on your seal, we have an assortment of thin rope gaskets for this matter.

What kind of gaskets does Fast Replacement Glass carry?

We carry a wide selection of gaskets including flat, rope, and tadpole (or "bulb and tail") varieties. Our products are made from graphite-impregnated fiberglass for extra strength and durability, and come in a range of sizes from 3/16" - 1" in diameter. All of our gaskets carry a rating of 1000°F (538°C) and are bondable to most materials. You can rest assured that our door and window seals will direct gases and fumes through your stove's or fireplace's flue system, rather than back into your living space. It will control the amount of air that is permitted to enter the firebox or hearth, thereby promoting an efficient burning fire!

How do I know which is the right door seal for my application?

Fast Replacement Glass recommends reading your stove or fireplace owner's manual if you're unsure about which type and size (diameter) gasket you'll need for your door or window glass.

Let's assume the gasket information in your owner's manual is not readily available. Look at the old seal in your stove. You'll notice that it is, most likely set in a groove. To keep it in place, a cement was used. However, if it was a poor quality adhesive, this can cause early failure of the seal. Inferior products will deteriorate under the intense heat from the fire, eventually coming loose or even falling away from the door.

Fast Replacement Glass only offers professional grade, high temperature cements and adhesives that carry manufacturer names we know and trust. These high quality products are guaranteed to withstand thermal shock and last far longer than the factory seals and cements.

How do I measure my old gasket to determine which type and size I should get from Fast Replacement Glass?
