AllFuel HST 38″ to 70″ Telescoping Pipe for 8″ Diameter Black Single Wall Stove Pipe
Best for long vent runs where maximum adjustment is needed. This 38″–70″ model uses 21-gauge steel, thicker than standard options, and is finished with high-temperature black paint to resist chipping. The product is designed so the pipe cannot be cut and must be used in a telescoping configuration, simplifying measurement accuracy for tall installations. Choose this if your stove location requires a tall, adjustable section and you want a robust steel wall for durability.
Best used for: mid-to-long indoor vent runs where precise length is critical and frequent adjustments may be required. Caution: not designed to cut down for shorter applications; ensure clearance from combustibles with the recommended install distances.
AllFuel HST 18″ to 30″ Telescoping Pipe for 8″ Diameter Black Single Wall Stove Pipe
Best for compact spaces or shorter vent lines. The 18″–30″ range provides a smaller adjustability window but maintains the same 21-gauge steel construction and heat-resistant black finish. This option is ideal when your setup needs a short, adjustable section that still benefits from thicker steel and a durable finish. It’s a reliable choice for limited ceiling height or close-to-stove installations.
Best used for: tight spaces, baseboard-to-stove configurations, or scenarios where full-height tall runs aren’t feasible. Caution: shorter length requires careful planning to avoid frequent re-measuring in tight areas.
Yaocom 1 Pcs 8″ Single Wall Stove Pipe 38″ to 70″ Telescoping
Best for versatile indoor installations that require a long adjustable reach. This Yaocom model uses carbon steel and a heat-resistant black powder finish for corrosion resistance. It is designed with a 38″–70″ telescoping range and emphasizes safe indoor use with appropriate clearances from combustibles. This is a good pick when you want a balance of sturdiness and flexible length in a single, managed unit.
Best used for: installations where a strong, long telescoping pipe is needed, and where indoor-only use is assumed. Caution: the product is intended for indoor environments; exposure to outdoor elements is not advised.
Yaocom 2 Pcs 8″ Telescoping Pipe 38″–70″
Best for installations that benefit from extra reach and a paired approach. This two-pack provides extra flexibility for longer or multi-section vent runs, using carbon steel and a heat-resistant finish. The stability of a two-piece set helps ensure a snug fit when assembling indoors, with the same safety clearances as other 8″ options. Choose this if you want redundancy in parts for larger projects or future expansion.
Best used for: projects that may require spare sections or combined lengths to reach distant venting points. Caution: ensure both pieces are compatible with your existing fittings and that installation guidelines are followed.
8in x 38in to 70in Single Wall Black Telescoping Stove Pipe — Rockford Chimney Supply
Best for a balance of strength and fit. This option notes a thicker wall at 22 gauge with .030 steel and features laser-welded seams for a round, consistent pipe-to-pipe fit. The 38″–70″ range supports long installations, while the welded seams aid in durability. This is a solid choice when you want a robust, dependable pipe with proven seam technology.
Best used for: installations requiring tighter seam integrity and a stout build. Caution: ensure compatibility with existing Rockford fittings and that the longer length does not exceed available vertical space.
Heat-Fab 2806B 8″ x 38″–70″ Adjustable Pipe Length
Best for versatile, no-cut installations. This Heat-Fab option is adjustable from 38″ to 70″ and emphasizes a seal that minimizes smoke or fuel leakage. The design aims to simplify installation by avoiding cutting or crimping, which can speed up setup while maintaining a reliable fit. It’s a practical pick for standard chimney runs with established clearance guidelines.
Best used for: straightforward installations where a clean, adjustable length source is desired and cutting is undesirable. Caution: confirm that your vent pathway aligns with the 38″ minimum length and clearance requirements.
Buying Guide: Key Considerations for 8-Inch Telescoping Stove Pipe
- Diameter compatibility: Ensure your stove outlet and chimney connector match 8 inches and that the interior bore is compatible with your stove’s exhaust.
- Telescoping range: Longer ranges (like 38″–70″) provide flexibility for tall ceilings; shorter ranges (18″–30″) suit compact spaces.
- Wall thickness and gauge: Thicker steel (lower gauge number) offers more durability and heat resistance. Compare 21–22 gauge to typical lighter options.
- Finish and corrosion resistance: A high-temperature black finish helps prevent chipping; powder-coated variants offer additional rust resistance for indoor use.
- Installation clearances: Adhere to safe distances from walls and ceilings to prevent heat exposure to combustibles. Indoor-use only recommendations must be followed for each model.
- Seam construction: Laser-welded or solid seams minimize leakage and improve fit; check for roundness and consistency in the joints.
- Number of pieces: Single-pipe vs. multi-pack options impact flexibility for future expansions or replacements.
- Maintenance access: Some tees or cleanouts improve inspection and cleaning; consider whether you need a cleanout option in your setup.
Frequently Asked Questions
- What is telescoping stove pipe?
It is a length-adjustable, typically 8-inch diameter stove pipe that can extend or retract to fit different ceiling heights or vent paths.
- Can I cut telescoping stove pipe to shorten it?
Most single-wall telescoping pipes are designed to be used as-is and cannot be cut down; cut-to-length adaptations should be avoided unless the manufacturer states otherwise.
- Which gauge steel is best for indoor use?
Thicker gauges (lower gauge numbers, such as 21–22) provide greater rigidity and heat resistance, which is beneficial for indoor, long-running installations.
- Are there safety restrictions for indoor use?
Yes. Indoor use typically requires specific clearances from combustibles and adherence to venting guidelines. Outdoor exposure is not advised for some models.
- Is a cleanout tee beneficial?
Cleanout options help with maintenance and inspection, particularly for rear-vent installations or complex vent paths.
