2" Catalytic Gasket Wrap

2 Inch Gasket Wrap | Combustor Gasket



Please Select Your Desired Gasket Length


This 2 inch wide catalytic combustor gasket is also known as interam wrap. Fast Replacement Glass offers this universal gasket to help seat your new combustor. The interam gasket will expand when exposed to high heat in the combustor chamber. Fast Replacement Glass recommends replacing it when you remove the combustor, as it will crumble and deteriorate under the duress of your heating stove. Water particles are embedded in the spongy gasket. When exposed to heat, the gasket will expand and release these particles to help protect the combustor and keep your stove from overheating.

When installing your new combustor with a gasket, always replace the interam wrap. Allow some room so the combustor and gasket can expand when you have your fire going. If you install your combustor with no visible extra space, the combustor might fracture or the stove components could overheat. We recommend monitoring the condition of the gasket material periodically. If it is showing signs of wear and tear, you will need to replace it. Since this material is so affordable, you may want to stock up on an extra gasket or two!


  • Never use combustor gasket for any other woodstove of fireplace applications.
  • Never pack your new combustor with any gasket into the combustor housing.
  • When heated gasket can double in thickness
  • Allow a visible space so the combustor can expand
  • Consult owners manual of stove or fireplace if a interam gasket is needed
  • Depending on how often you use your stove, the interam material may need to be replaced more than two or three times annually
  • Both canned and uncanned combustors can use this gasket - if your catalytic combustor was wrapped with interam, you need this component!

What size do I need?

  • Rectangular Combustor = add the length of all 4 sides together and round up to the next foot.
  • Round Combustor = Multiply your diameter by 3.14 and round up to the next foot.
