Wood Stove Door Gasket Replacement.
New rope gasket has a round shape and is braided (hence its name – rope gasket). Once installed and as the door is tightly closed, it is designed to flatten and fill the space between the door and the wood stove frame for an airtight seal.
If you don't have the correct size, you will not get a good seal. This can reduce your wood stove efficiency, resulting in burning more wood and having a harder time controlling the fire. Here's what you can do to determine the correct size:
So how do you measure sizing for a wood stove gasket?
- Check out the old wood stove seal. Try to choose a section that does not look as worn as the rest of the gasket. Then you can measure the width and depth of the channel.
- Using a flat head screwdriver, pry that section of the old gasket out of the channel. You just need to pull out enough to see the width of the channel and measure with a ruler or tape measure.
- Measure across the gasket channel (in inches). Usually in ¼”- 3/8”- ½” - 5/8” – ¾” – 7/8” or 1” thickness.
- Remove any gasket cement that may remain in the channel. Once it is clean, you can measure the depth of the channel.
- Look over the two measurements' width and depth and choose the largest measurement of the two so that your new replacement gasket will fill and seal the channel.
- If you can mold your old gasket back so it is round, try placing a ruler across it to measure the width. This additional measurement can give you a very better indication of what diameter wood stove gasket to order.
- It is a good idea to order a little more gasket than you need. Typically, about one foot more than your final measurement just in case.

I am the original owner of a Wonder Warm stove since 1979. Within the first year I had problems with the roping seal being cut in half and falling off. I stopped replacing the seal , but with costs of everything going only in 1 direction ⬆️ i am going to add a smaller diameter
(3/8") seal to just the outside edge of of the slot on the doors. I will get back to this forum and let you all know. The company that made the stove Dunham Lehr got out of the wood stove manufacturing in the early 80’s. It is a very well made stove but their design of a 90° “L” angle around the edge of the hearth opening was a bad idea and I told them that on the phone, I told them my idea and they loved it! Apparently the handwriting was already on the wall to shut it all down. They are still in the farm equipment buissness at a new location.

I was advised to use 5/8" rope gasket. The channel measures 5/8". Now that I’ve installed it I can not get the door to close. Any help appreciated.
I have a surefire 201a, and can’t find the right size door seal gasket
i have a pacific energy vista LE. about 15 years old. i need to replace the door seal again. just put a 7/8 seal but it still leakes air. i think its tall enough im the door channel just not thick enough to the stove to make a thght seal. A 1 inch would be taller in the channel but i need it thicker to the stove. dont the seals come in 2 dimensions? any help would be appreciated

do you have door seal rope 1 1/5 inch X 13 feet
An often overlooked yet crucial component, the door gasket plays a silent but effective role in ensuring a tight seal, keeping the elements out and the comfort in. It’s the unsung hero of your door, quietly working to maintain energy efficiency and protect your space from drafts. A small detail with a big impact!"
