The Selkirk 256240 is a chimney pipe adapter designed for use in residential and commercial venting systems. It connects chimney flue sections or transitions between pipe components where a secure, properly sealed joint is required. HVAC technicians, chimney installers, and fireplace contractors rely on adapters like this to ensure a tight, code-compliant connection when joining chimney pipe runs or adapting between sections of a venting system. The Selkirk 256240 measures 5.93 inches in diameter and is constructed from stainless steel with a black finish, giving it both durability and a clean appearance in visible installations. Stainless steel construction provides resistance to corrosion, heat, and the acidic byproducts that form inside chimney flues over time. This makes the adapter suitable for use with wood-burning appliances, gas fireplaces, pellet stoves, and other solid or liquid fuel heating equipment where flue gases can be particularly harsh. The black finish blends with common chimney pipe systems and adds a layer of heat-resistant coating to the exterior surface. At 8.3 inches in height, 8.2 inches in length, and 4.2 inches in width, this adapter is compact and easy to handle during installation in tight spaces such as attic chases, wall cavities, or near fireplace hearths. Weighing just 0.6 pounds, it is lightweight enough to position and secure without additional support during fitting. Selkirk is a well-known manufacturer in the chimney and venting industry, producing components trusted for consistent fit and reliable performance across a wide range of venting applications. This adapter is a practical solution for chimney system repairs, new installations, and retrofit projects where a reliable pipe-to-pipe transition is needed.
