The best coal stove chimney pipe is the one that matches the stove manufacturer’s venting requirements, flue diameter, fuel type, and installation layout. Among these options, DuraVent DuraPlus is the clearest choice for buyers who need a listed, triple-wall chimney system described for coal; the 24-inch and 36-inch lengths suit different layout needs. A 12-inch section can help with shorter runs, while the separate chimney cap is an accessory, not a replacement for the required chimney system.

|---|---|---|
| DuraVent DuraPlus 6 x 24 | Buyers needing a shorter section | Triple-wall, all-fuel listing in product details |
| DuraVent DuraPlus 6 x 36 | Buyers needing a longer section | Triple-wall construction and twist-lock system |
| DuraVent DuraPlus 6 x 12 | Short additions or layout adjustments | Triple-wall construction |
| DuraVent 9017SSCF 6 x 36 | Buyers comparing a 36-inch straight length | 6-inch diameter and 36-inch length |
| CLLOMAGY 6-inch chimney cap | Buyers seeking an exterior cap for a compatible pipe | Screened, cone-top cap for specified single-wall pipe |
DuraVent DuraPlus 6 x 24-Inch Chimney Pipe

Best for: Buyers who need a 24-inch section for a DuraPlus chimney layout and want product details that explicitly include coal among the supported fuels. Its listed 6-inch diameter provides a clear specification to compare with the stove’s required flue size.
This DuraVent DuraPlus section uses triple-wall construction, including a stainless steel inner liner and insulation layers described as a ceramic blanket and air space. The listing says the system is intended for wood, oil, coal, and gas appliances, and identifies UL 103HT listing information. These stated specifications make it the strongest match in this selection for a buyer prioritizing coal-fuel documentation.
- 24-inch length and 6-inch diameter.
- Triple-wall design intended to maintain a hot interior draft and cooler outer wall.
- Product details cite continuous 1,000°F flue temperatures and 2,100°F chimney-fire testing.
Why it was selected: The fuel list explicitly names coal, and the shorter length may suit installations where a 36-inch section is not appropriate. Limitation: A pipe section alone does not establish that an entire installation is complete or suitable; confirm the required DuraPlus components and clearances in the appliance and system instructions.
DuraVent DuraPlus 6 x 36-Inch Pipe

Best for: Buyers who need a longer 6-inch DuraPlus section and want a product description that names coal as a fuel. At 36 inches, this section is longer than the 24-inch and 12-inch alternatives in this selection.
The listing describes a galvanized-steel DuraPlus triple-wall pipe with a twist-lock connection system. It says the DuraPlus line is designed to vent exhaust from wood, oil, coal, and gas combustion sources. Die-formed fittings and twist-lock connections are described as features of the product line, supporting buyers comparing installation-system details.
- 36-inch length and 6-inch diameter.
- Triple-wall construction and twist-lock connection system.
- Product details describe use with coal and other listed fuel types.
Why it was selected: It combines an explicitly stated coal-fuel application with a longer section length, making it a useful comparison against the 24-inch DuraPlus pipe. Limitation: The listed 17.56-pound weight may matter when planning handling and installation. Check the exact system instructions and required parts; a single length is not a complete chimney.
DuraVent DuraPlus 6 x 12-Inch Section

Best for: Buyers who need a shorter section for a compatible DuraPlus layout. A 12-inch length offers a different sizing option from the 24-inch and 36-inch products, but the required installed length depends on the actual system and its instructions.
The product details describe a triple-wall assembly with a stainless steel inner liner, an aluminized steel intermediate liner, and a stainless or galvanized outer wall. The insulation combines a refractory ceramic blanket with a thermal air space. The listing also describes radial expansion of the compressible blanket during extreme creosote fires.
- 6-inch diameter and 12-inch nominal length.
- Triple-wall construction with multiple liner materials.
- Insulation and radial expansion are described in the product features.
Why it was selected: A shorter section can be useful when comparing component lengths for a planned installation, and the DuraPlus description includes construction details relevant to chimney-system selection. Limitation: The supplied features for this specific listing do not state coal compatibility as directly as the 24-inch listing does. Verify fuel approval for the exact component and appliance before purchase.
DuraVent 9017SSCF 6 x 36 Straight Pipe

Best for: Buyers comparing a 36-inch, 6-inch straight pipe length from the DuraPlus series. Its basic dimensions are stated clearly, which helps with initial size comparisons when planning a compatible system.
The listed features identify this as a DuraVent 9017SSCF Class-A chimney boxed straight pipe length. It is 36 inches long, measures 6 inches in diameter, and is described as having an easy in-and-out fit. Those details make it a straightforward alternative to the other 36-inch DuraPlus option in this list.
- 36-inch length.
- 6-inch diameter.
- Described as a Class-A chimney straight pipe length from the DuraPlus series.
Why it was selected: It gives buyers another 6-inch, 36-inch DuraPlus-series option to compare when matching a straight section to a system plan. Limitation: The supplied feature list does not specify fuel compatibility, connector type, or all installation requirements. Confirm the complete product documentation and compatibility with a coal stove before selecting it.
CLLOMAGY 6-Inch Screened Chimney Cap

Best for: Buyers looking for an exterior cap to help keep rain, snow, leaves, and small animals out of a compatible 6-inch flue. This is an accessory for the end of a chimney, not a substitute for chimney pipe or a full venting system.
The product is described as a cone-top cap with a screen and galvanized-steel construction. Its features state that it is designed for a 6-inch outside-diameter chimney flue pipe and single fireplace pipes. The listing also explicitly warns that it is not compatible with double fireplace pipes.
- 6-inch size for the specified outside pipe diameter.
- Screen intended to help block leaves, precipitation, and small animals.
- Galvanized steel described as corrosion-resistant and suitable for outdoor exposure.
Why it was selected: A cap is a relevant accessory to compare when completing an exterior venting plan, and the product states its size and a key compatibility restriction. Limitation: Do not assume it fits a double-wall or other chimney system; verify the pipe’s outside diameter and the manufacturer’s cap requirements first.
Buying Guide: How to Choose Coal Stove Chimney Pipe
Does the product explicitly support coal?
Start with the coal stove manufacturer’s venting instructions. Product listings may describe a pipe as suitable for multiple fuels, but the full chimney assembly must also meet the stove’s requirements. In this group, the 24-inch DuraPlus listing expressly names coal. The 36-inch DuraPlus listing also names coal in its fuel description. For other products, confirm fuel approval in the manufacturer’s documentation rather than assuming it from appearance or product-family name.
What diameter does the stove require?
Match the pipe diameter to the appliance’s specified flue outlet and the approved venting design. The listed DuraVent options here have a 6-inch diameter, but that does not mean 6 inches is correct for every coal stove. Do not reduce or enlarge the flue size unless the stove instructions and applicable requirements permit it.
Is this connector pipe or chimney pipe?
Venting products can serve different roles. A stovepipe connector typically links an appliance to a chimney system, while chimney sections form the chimney itself. The product names and descriptions here include Class-A and triple-wall chimney products, but the exact role and required components should be confirmed from the manufacturer’s installation guide. Do not treat a single section as a complete venting system.
How should you compare pipe lengths?
Choose a length based on the planned route and the system’s installation requirements, not simply the fewest pieces. The listed DuraPlus lengths are 12, 24, and 36 inches. Compare their nominal dimensions with the actual installed length and connection requirements specified by the manufacturer. Avoid cutting or modifying chimney sections unless the product instructions explicitly allow it.
What should you check about construction and safety?
Look for documented system standards, approved components, and installation instructions. The 24-inch DuraPlus listing supplies UL 103HT information and describes triple-wall construction with insulation; use the product documentation to confirm that the exact part and complete system meet the stove’s requirements. Follow specified clearances from combustible materials, support requirements, and roof or wall penetration details. When uncertain, consult a qualified installer or local building official.
Does a chimney cap fit every pipe?
No. Check the cap’s stated diameter, pipe outside diameter, and wall construction. The CLLOMAGY listing specifies a 6-inch outside diameter and says it is not compatible with double fireplace pipes. That restriction is especially important: a cap that appears to be the right nominal size may still not match the chimney system. Follow the chimney manufacturer’s approved cap guidance.
Frequently Asked Questions
What chimney pipe should I use for a coal stove?
Use the venting system specified by the coal stove manufacturer and verify that every component is approved for the appliance and fuel. In this selection, DuraVent DuraPlus listings that explicitly name coal are the clearest starting point, but the complete installation must still follow system instructions.
Can I use a 6-inch pipe with any coal stove?
No. A 6-inch diameter is suitable only when it matches the stove’s specified flue size and approved venting design. Check the appliance manual before buying pipe.
What is the difference between 12-, 24-, and 36-inch sections?
The listed sections differ in nominal length. Choose the length that fits the approved route and connection plan; confirm actual installed dimensions and system requirements in the manufacturer’s documentation.
Can I connect chimney sections from different brands?
Do not assume that different brands or product lines connect safely or are approved together. Use components specified for the same compatible chimney system unless the manufacturers clearly document otherwise.
Does a chimney cap replace chimney pipe?
No. A cap is an accessory fitted to a compatible chimney termination. It does not provide the pipe, supports, clearances, or other components needed for a complete venting system.
What is the most important installation check?
Confirm that the complete venting system matches the stove’s fuel, flue size, and installation instructions. Also follow required clearances and local rules, and have the design reviewed by a qualified professional when necessary.
