Seal-tite 1245-1810 Rectangular Shortway Duct Elbow

Product Description

The SEAL-TITE 1245-1810 is a rectangular shortway duct elbow fabricated from 26-gauge galvanized metal, designed for directional changes in low-pressure HVAC duct systems. Measuring 18 inches by 10 inches, this fitting redirects airflow along the short dimension of the duct — the shortway orientation — making it well suited for installations where ceiling height or structural clearances are limited. The hemmed collar and double-lapped, mechanically seamed corner construction create a leak-resistant joint that meets the demands of commercial and residential sheet metal work. HVAC technicians and sheet metal contractors install this fitting as part of trunk-and-branch or plenum distribution systems.

This elbow is appropriate for rectangular duct runs in residential forced-air systems, light commercial air distribution, and retrofit applications where existing duct geometry requires a low-profile directional change. The 18-inch by 10-inch face size fits standard rectangular duct of that cross-section. Its engineered throat and radii reduce turbulence and static pressure loss at the turn. Compliance with CCR Title 24 and IECC standards makes it suitable for projects subject to energy code inspection in applicable jurisdictions.

Key Features

• Shortway rectangular elbow for space-constrained directional changes in duct runs
• 26-gauge galvanized metal construction for corrosion resistance and structural rigidity
• Hemmed collar provides a secure, leak-resistant connection to adjoining duct sections
• Double-lapped, mechanically seamed corner and joint for a fully closed, Leak-Tite fit
• Engineered throat and radii minimize turbulence and pressure drop through the turn
• Meets CCR Title 24 and IECC applicable standards for energy-code-compliant installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for rectangular galvanized duct systems with an 18-inch by 10-inch cross-section.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handling unit and de-energize the system before making duct modifications. Secure the elbow to adjoining duct sections using sheet metal screws and approved duct sealant or mastic in accordance with SMACNA guidelines and local mechanical code requirements. Do not use this fitting in applications that exceed the pressure rating of 26-gauge galvanized duct construction.
