The best adjustable wood stove pipe depends on the required diameter, length, and clearance from nearby combustibles. For a 6-inch single-wall connection, Metlead’s 18–30-inch model suits shorter gaps, while its 38–70-inch model covers longer runs. DuraVent’s double-wall telescoping options are better suited to installations where reduced clearances are important. Measure your stove collar and chimney connection before choosing.

|---|---|---|---|
| Metlead 6-Inch Telescoping Pipe | Single wall | 18–30 inches | Short gaps |
| DuraVent DVL Telescoping Pipe | Double wall | 40–68 inches | Longer runs and close-clearance needs |
| DuraVent DVL46-TA | Double wall | Not stated | Connecting a stove to a ceiling support or finishing collar |
| Metlead 6-Inch Telescoping Pipe | Single wall | 38–70 inches | Long straight connections |
| Yaocom 6-Inch Telescoping Pipe | Single wall | 48–64 inches | Longer 6-inch connections |
Metlead 6-Inch Pipe, 18–30 Inches
This Metlead telescoping connector adjusts from 18 to 30 inches. It is made from 1.0 mm carbon steel and has a heat-resistant black finish. The two-piece design is intended to fit the measured distance between a wood stove and its chimney connection without cutting the pipe.
Best for: Buyers with a compatible 6-inch system and a relatively short connection gap. The included 15 screws are specified for securing the telescoping sections after the pipe is adjusted.
Why it was selected: Its compact adjustment range makes it a straightforward option when longer telescoping sections would be unnecessary.
Limitation: The maximum stated length is 30 inches, so it is not suited to a longer gap. This is single-wall pipe; verify required clearances and the applicable installation instructions before buying.
DuraVent DVL Double-Wall Pipe, 40–68 Inches
This 6-inch DuraVent DVL connector telescopes from 40 to 68 inches. Its double-wall, air-insulated construction is described as allowing a 6-inch clearance from walls and an 8-inch clearance from ceilings. The stainless-steel inner wall is designed to heat quickly and stay hot longer, supporting draft and helping limit creosote accumulation.
Best for: Buyers who need a longer adjustable section and are considering double-wall pipe for a close-clearance installation. Its no-cut design avoids field cutting or crimping.
Why it was selected: It offers the clearest stated clearance information among the listed long adjustable options, along with a defined 40–68-inch range.
Limitation: The range starts at 40 inches, making it a poor fit for shorter connections. Confirm that the stated clearances and product configuration match the stove, chimney system, and local requirements.
DuraVent DVL46-TA Telescoping Connector
The DuraVent DVL46-TA is described as a double-wall finishing pipe that bridges a stove and a ceiling support box or finishing collar. Its product information highlights adjustable lengths and die-formed fittings, which are designed to avoid cutting or crimping the ends. The listing also describes the venting system as handling emissions from wood, oil, coal, and gas appliances.
Best for: Buyers whose installation calls for a DVL finishing connector between a stove and a ceiling support or finishing collar.
Why it was selected: Unlike a generic straight connector, its stated role is specifically to create this bridge as part of a two-piece arrangement.
Limitation: The supplied product details do not state an adjustment range or pipe diameter. Confirm both measurements and system requirements before ordering rather than assuming they match another DVL component.
Metlead 6-Inch Pipe, 38–70 Inches
This Metlead single-wall pipe adjusts from 38 to 70 inches and is made from 1.0 mm carbon steel. It has a heat-resistant black finish and a two-piece telescoping construction. The package includes 15 screws to secure the sections after the pipe is set to the required length.
Best for: Buyers who need a long straight 6-inch connector and want an adjustment range that extends to 70 inches.
Why it was selected: Its 38–70-inch range covers longer gaps than the shorter Metlead model while retaining the same stated steel thickness and screw-in section fastening.
Limitation: It is single-wall pipe, and its minimum length is 38 inches. It will not suit a short connection or an installation that requires a double-wall connector. Check the required clearance for the specific installation.
Yaocom 6-Inch Pipe, 48–64 Inches
This Yaocom connector is a 6-inch single-wall telescoping pipe that adjusts from approximately 48 to 64 inches. The listing describes a sturdy black steel construction and a matte finish. Its adjustable structure is intended to connect a compatible stove outlet to an existing chimney system without cutting fixed-size pipe sections.
Best for: Buyers with a 6-inch system whose measured connection falls within the 48–64-inch range.
Why it was selected: Its range is a useful middle-to-long option for installations that are too long for a short telescoping connector but do not need a 70-inch maximum.
Limitation: The listed features do not specify a steel gauge or included fasteners. Verify the product’s fit and installation requirements before purchase, and do not treat a single-wall connector as a substitute for a required double-wall section.
Buying Guide: How to Choose Adjustable Stove Pipe
What diameter does your stove use?
Start by checking the stove collar and the chimney connector specifications. The four featured Metlead, DuraVent DVL, and Yaocom options are identified as 6-inch products, but the DVL46-TA details provided here do not state a diameter. A pipe that looks close in size is not a reliable substitute for a connector specified for the correct system.
The product list also includes 8-inch Yaocom pipes, but they are not included among the five recommended products above because the comparison focuses on the 6-inch options. If your stove requires an 8-inch connector, check the exact model and size rather than selecting a 6-inch pipe based on length alone.
How do you measure the required length?
Measure the connection path between the stove outlet and the compatible chimney connection, following the product and appliance instructions. Then compare that measurement with the pipe’s full adjustment range. The connector must fit within its stated minimum and maximum; telescoping does not mean that every length is possible or appropriate.
For a shorter gap, the Metlead 18–30-inch model is the most directly matched choice in this group. For a connection longer than 30 inches, compare the Metlead 38–70-inch pipe, the DuraVent 40–68-inch model, and the Yaocom 48–64-inch option against the measured span.
Should you choose single-wall or double-wall pipe?
Single-wall and double-wall connectors differ in construction and installation requirements. The Metlead and Yaocom featured here are single-wall products. The DuraVent DVL options are described as double-wall. The DVL 40–68-inch listing provides specific wall and ceiling clearance figures; use the manufacturer’s instructions and local rules to determine whether those clearances apply to your installation.
Do not choose a pipe based only on the advertised clearance or its appearance. Check the stove manual, chimney system documentation, and applicable codes. A connector’s product description does not replace the requirements for the complete venting system.
Do you need a straight connector or a finishing piece?
Most options in this comparison are telescoping straight pipe sections for bridging a measured gap. The DVL46-TA is described more specifically as a finishing pipe between the stove and a ceiling support box or finishing collar. Confirm the role of each component in your planned setup so you do not purchase a straight pipe when a particular transition or finishing part is required.
What construction and installation details should you compare?
- Adjustment range: Choose a minimum and maximum length that include your measured connection.
- Material details: Metlead specifies 1.0 mm carbon steel; Yaocom’s 48–64-inch listing describes sturdy black steel but does not provide a gauge in the supplied features.
- Fasteners: The two Metlead models list 15 screws. The other product descriptions provided do not specify included screws.
- Cutting and fitting: The DuraVent 40–68-inch connector is described as no-cut, and the DVL46-TA features adjustable lengths and die-formed fittings.
- Finish: Metlead specifies a heat-resistant black finish. Yaocom describes a black matte finish on its 6-inch product.
Follow the product’s assembly instructions when adjusting and fastening the pipe. Do not improvise a connection or assume that a telescoping joint can remain unsecured; the Metlead listing specifically calls for screws to secure its sections after adjustment.
Frequently Asked Questions
What is an adjustable wood stove pipe?
It is a stove pipe section that telescopes to provide a range of lengths. It can help bridge a measured gap between a compatible stove outlet and chimney connection without cutting a fixed-length pipe, when the product design and installation instructions allow it.
How do I know which adjustable length to buy?
Measure the required connection and choose a product whose stated minimum and maximum lengths cover that measurement. Confirm the pipe diameter and connection requirements as well; length alone does not establish compatibility.
Is double-wall stove pipe always better than single-wall?
Neither type is automatically right for every setup. Double-wall construction may be relevant where clearance requirements affect the connector choice, while single-wall pipe has different installation requirements. Follow the appliance and venting-system instructions and local codes.
Can I cut an adjustable stove pipe to fit?
Do not assume that cutting is allowed. Some telescoping models are specifically promoted as no-cut designs. Follow the manufacturer’s directions for the exact pipe, and avoid modifying a component unless its instructions permit it.
Does a telescoping pipe replace the chimney system?
No. A telescoping stove pipe is a connector component, not a complete chimney system. Confirm that it connects to the appropriate stove and chimney components and that the entire installation follows the relevant instructions and requirements.
