The best pellet stove termination cap depends on whether your vent exits through a wall or a roof and whether the cap matches your vent system. For a horizontal outlet, compare the DuraVent 3-inch swivel cap with the Zonon galvanized-steel cap; for vertical terminations, consider the Selkirk or DuraVent vertical caps. The DuraVent horizontal tapered-end cap is another possible match, but its supplied feature information does not describe a vent cap, so verify the product details before buying.
| Product | Best suited for | Key detail to check |
|---|---|---|
| DURAVENT 3PVP-HC2 Horizontal Cap | Buyers seeking a horizontal DuraVent cap | Confirm product specifications; listed features conflict with the product name |

| M&G DuraVent 179103 Horizontal Swivel Cap | Buyers seeking a 3-inch horizontal cap | Confirm it matches the vent system |
| Selkirk 243800 Vertical Termination Cap | 3-inch vertical Type L pellet vent | Confirm the vent type and model |
| M&G DuraVent 3-Inch Vertical Cap | Buyers looking for a 3-inch vertical cap | Check model and system compatibility |
DURAVENT 3PVP-HC2 Horizontal Cap
The product name identifies this item as a DuraVent PelletVent Pro horizontal cap with a tapered end and stainless-steel construction. Those details make it a potential option for buyers looking for a horizontal termination cap in that product line. The listed features, however, describe leather, jacquard, satin, and padded sock lining rather than a vent component.
Best for: A buyer who has independently confirmed that the item is the specified DuraVent cap and that it matches the existing vent system. It was selected because the product name directly identifies it as a pellet vent horizontal cap.
Limitation: The mismatch between the product name and the supplied feature list makes this listing less straightforward to evaluate. Do not rely on the feature text to confirm its construction or fit; verify the model and specifications before purchase.
Zonon 3-Inch Horizontal Swivel Cap
The Zonon cap is described as a galvanized-steel square wall cap with a round 3-inch connector. Its listing says it is designed for horizontal terminations, not vertical chimneys. It is intended to help keep rain, snow, and debris from entering the exhaust passage, while its galvanized steel is described as water-, rust-, and corrosion-resistant.
Best for: Buyers seeking a horizontal wall termination cap with a galvanized-steel body and a 3-inch connector. It stands out for explicitly stating its horizontal-only use and material.
Limitation: The listing gives a body size of 25 x 17 x 5.91 inches as well as the 3-inch connector measurement. Confirm those dimensions against the available installation space and the product before ordering.
DuraVent 179103 Horizontal Swivel Cap
The M&G DuraVent 179103 is identified as a 3-inch square horizontal swivel cap, also named 3PVP-HSC. The supplied features describe a 3-inch size, an “easy in-and-out fit,” and high efficiency. The available information does not give further material or installation details.
Best for: Buyers who need a 3-inch horizontal swivel cap and have confirmed that the 3PVP-HSC model fits their vent system. Its stated size and horizontal-cap designation make it easier to compare with other horizontal options.
Limitation: The feature list is brief. It does not specify construction material or provide detailed fit information, so check the model designation and the vent manufacturer’s requirements before choosing it.
Selkirk 243800 Vertical Termination Cap
The Selkirk 243800 is a 3-inch vertical termination cap identified for model VP Type L pellet vent. Its listed features describe a round-top termination cap that helps protect the vent system from rain and other elements. These details make it a more specific match for a vertical Type L pellet vent than a cap labeled only by diameter.
Best for: Buyers with a vertical 3-inch Selkirk model VP Type L pellet vent who need a cap intended to protect the termination from weather. It was selected because the product information names both its vertical use and vent type.
Limitation: The listing identifies a particular vent system. Do not assume that a matching 3-inch diameter alone makes it suitable for another brand or vent type.
DuraVent 3-Inch Vertical Cap
This M&G DuraVent product is named a PelletVent vertical cap, model 3PVL-VCR. The provided feature information specifies a 3-inch size but does not include further details about materials, weather protection, or installation. The product name therefore provides the main basis for comparing it with the other vertical option.
Best for: Buyers searching for a 3-inch DuraVent PelletVent vertical cap who can verify the model against their installed vent. It was selected because its product name directly identifies the vent application and orientation.
Limitation: The supplied features contain only the diameter. Confirm the model designation and system fit rather than using the 3-inch measurement as the sole compatibility check.
Buying Guide: How to Choose a Pellet Stove Termination Cap
Does your vent exit through a wall or roof?
Start by identifying the termination direction. A horizontal cap is intended for a vent that exits through a wall; a vertical cap is intended for an outlet that terminates upward. These are not interchangeable categories. The Zonon listing explicitly limits its cap to horizontal use, while the Selkirk and DuraVent vertical products are identified as vertical caps.
Check the vent route and the cap’s stated orientation before comparing materials or features. If you are replacing an existing cap, note how the vent terminates and record the current component’s model information where available.
Is the diameter enough to confirm a match?
No. Diameter is an important measurement, but the product information also needs to match the vent system and model. For example, the Selkirk cap is identified for a model VP Type L pellet vent, while the DuraVent products include specific model names. A 3-inch measurement by itself does not establish compatibility.
Compare the cap’s model and product-line designation with the installed vent components and the stove or vent manufacturer’s instructions. When those details are unclear, confirm them before ordering rather than relying on a similar-looking product or matching diameter alone.
What material and weather details should buyers compare?
The Zonon listing specifies galvanized steel and says the cap is designed to help block rain, snow, and debris from a horizontal exhaust outlet. The DuraVent 3PVP-HC2 product name identifies stainless steel, but its supplied feature list conflicts with that product description. The other listings provide limited material information.
Use only details that are clearly associated with the vent cap. If a listing’s text describes an unrelated product, as with the 3PVP-HC2 feature list, treat the information as uncertain and verify the item’s specifications before purchase.
How should you compare horizontal cap options?
For a 3-inch horizontal swivel cap, the DuraVent 179103 has a clear model designation and size, but limited feature information. Zonon provides more detail about its material, weather role, orientation, and connector, along with unusually large stated body dimensions that should be checked. The 3PVP-HC2 name offers a tapered-end stainless-steel option, but its listing information needs verification.
Choose based on confirmed model fit, termination direction, and installation dimensions. Avoid selecting solely by brand name, a broad “horizontal cap” label, or an unverified feature claim.
What should you check before ordering?
- Confirm whether the termination is horizontal or vertical.
- Match the cap’s stated vent type, model, and diameter to the installed system.
- Check connector and exterior dimensions, especially when the listing gives multiple measurements.
- Read the product details for information that actually applies to a pellet vent cap.
- Consult the stove or vent system instructions when compatibility or installation requirements are uncertain.
Frequently Asked Questions
Can I use a horizontal cap on a vertical pellet vent?
No. Choose a cap designed for the vent’s termination direction. The Zonon listing specifically states that its cap is for horizontal terminations only.
Does a 3-inch cap fit every 3-inch pellet vent?
Not necessarily. Diameter alone does not confirm compatibility. Check the vent type, model designation, and manufacturer requirements as well as the diameter.
What does a termination cap do?
A termination cap covers the end of a vent system. Product features in these listings describe protection against rain and other elements, and the Zonon listing also mentions snow and debris for horizontal outlets.
Which listed product is specifically identified for Type L pellet vent?
The Selkirk 243800 is described as a 3-inch vertical termination cap for model VP Type L pellet vent. Confirm that this matches the installed system before choosing it.
What should I do if product details conflict?
Verify the exact model and specifications before buying. The DURAVENT 3PVP-HC2 listing names a horizontal pellet vent cap, but its supplied features describe apparel rather than vent components.
