The AllFuel HST Pellet Vent 3" Adjustable Pipe Length is designed to provide the flexibility needed to complete your pellet vent installation when standard pipe lengths don't fit. The adjustable section slides over a rigid length of 3" AllFuel HST Pellet Vent Pipe, allowing you to adjust the installed length from 10" to 20" while maintaining a secure, leak-resistant connection.
The positive twist-lock connection provides a fast, secure fit without the need for screws or fasteners. Its dual-seal connection combines a metal-to-metal seal with an encapsulated O-ring gasket, eliminating the need for silicone during installation.
Note: Some stove manufacturers require silicone sealant despite the internal gasket. Always check your appliance manual for assembly instructions.
Note: The AFPV3-10-20-BLK is designed to slide over a rigid Pellet Vent pipe section to provide an adjustable installed length from 10" to 20". This makes it ideal for installations where a fixed-length pipe will not provide the exact fit required. Adjustable sections are commonly used to simplify installation and eliminate the need for custom vent modifications.
Built for durability, the AFPV3-10-20-BLK features a .019" thick TIG welded 444 stainless steel inner wall that resists corrosion from pellet, corn, and biofuel exhaust, along with a .019" laser welded Galvalume outer wall with a black powder-coated finish for added strength and protection against the elements. Backed by the AllFuel HST Limited Lifetime Warranty, this adjustable pipe section is built to provide years of dependable performance.
