Grae1490ga26 14-Inch Round 90° Elbow (LLPParts)
The Grae1490ga26 elbow is a galvanized steel, 14-inch duct elbow designed for 14-inch nominal duct systems. It features a 14-inch inlet and outlet, with a 17 1/2-inch overall length and a 26-gauge wall thickness. The product is described as an adjustable-style elbow suitable for straight and angled duct sections, with crimped ends for secure connections. A one-year warranty is noted, and the item is positioned for quick local delivery in multiple states. Typical applications include residential or light commercial air distribution where durable, corrosion-resistant joints are required.
Grae1490ga26 Round 90 Degree Elbow (Generic)
This listing mirrors the 14-inch, 90-degree galvanized elbow profile for Greenseam OEM compatibility with a 14-inch inside diameter and an overall height around 17 inches. The material is galvanized steel (26-gauge). It is sold under the Generic label, signaling a direct replacement part suitable for retrofits or new ductwork where a compatible elbow is required to maintain system integrity and airflow efficiency. The product is designed to resist corrosion and provide a stable, rigid connection in a duct run.
Grae1490ga24 14-Inch Round 90° Elbow (AMPLIPHASE)
The Grae1490ga24 elbow is a galvanized steel 14-inch 90-degree elbow intended for Greenseam Grae1490ga24 compatibility. The AMPLIPHASE-branded listing emphasizes durability, precise fabrication, and reliable performance in standard HVAC ductwork. With a 14-inch conduit diameter and 17-inch-plus length profiles, this elbow is suited for tight space routing where a right-angle turn is necessary without sacrificing airflow. The galvanized steel construction supports long service life in typical residential environments.
Speedi-Products FDSC-14 14-Inch Duct Splice Collar
The FDSC-14 is a 14-inch flex duct splice collar designed for joining two lengths of flexible or sheet metal round ducts. While not an elbow, it complements 14-inch duct runs by enabling secure, seamless connections between straight sections and elbows. It supports the use of approved duct mastic sealants to ensure airtight seals and maintain system efficiency. This accessory is suitable for retrofits, repairs, or custom duct routing where splicing is needed.
Sun Air 14-Inch 45° Duct Elbow
The Sun Air 14-inch 45-degree elbow is a stainless steel, single-wall grease duct elbow designed for kitchen ventilation and other grease-laden vapor exhaust applications. It is ETL-listed and UL CAN/ULC-compliant for grease duct installations, indicating adherence to safety standards in commercial and residential kitchen hood systems. The elbow is designed for no-weld installation, reducing on-site labor and costs, with corrosion resistance suitable for long-term use in environments requiring airflow and grease management.
Buying decisions for 14-inch duct elbows should consider material (galvanized steel vs. stainless steel), degree of bend (45° vs 90°), wall thickness (gauge), end connections (crimped or crimped-and-welded), and compatibility with existing duct systems. Galvanized steel provides strong durability for general HVAC runs, while stainless steel offers superior corrosion resistance for grease- and moisture-laden environments. Where space constraints demand flexible routing, lighter-gauge components or adjustable elbows can simplify installation but should be balanced with anticipated airflow and pressure loss. For retrofit projects, compatibility with existing duct diameters and end types is essential to ensure airtight seals and reliable airflow. Accessories like splice collars improve system integrity, especially when extending duct runs. When choosing, verify local codes and the duct material compatibility with grease ducts if kitchen ventilation is involved, and consider warranties and delivery options for timely project completion.
