Seal-tite DVLT90 Dryer Vent Elbow 90 Degree 4 in

Product Description

The SEAL-TITE DVLT90 is a 90-degree dryer vent elbow designed to redirect exhaust airflow in residential and light-commercial dryer installations. With a 4-inch diameter, a 10-inch bend radius, and an 18-inch overall length, this elbow provides a smooth directional transition that reduces backpressure compared to tight-radius fittings. HVAC technicians and appliance installers use this fitting to route dryer exhaust through walls, floors, or around obstructions while maintaining proper airflow for safe dryer operation.

This elbow is suited for residential laundry installations where the dryer exhaust duct must change direction by 90 degrees. The 10-inch radius bend supports adequate airflow velocity, which helps prevent lint accumulation inside the duct. It is appropriate for use with standard 4-inch dryer exhaust duct systems in single-family homes, multi-family units, and light-commercial laundry rooms.

Key Features

• 90-degree turn for routing exhaust around walls, floors, or structural obstructions
• 4-inch diameter matches standard residential dryer exhaust duct sizing
• 10-inch bend radius supports smooth airflow and reduces lint buildup potential
• 18-inch overall length provides generous reach for tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 4-inch residential dryer exhaust duct systems.

Installation Notes

Installation should be performed by a qualified HVAC technician or appliance installer following local mechanical codes and manufacturer guidelines. Always disconnect power to the dryer before disconnecting or modifying exhaust ductwork. Secure all duct connections with foil tape rated for dryer duct use — do not use standard plastic duct tape or sheet metal screws that protrude into the airflow path. Verify the completed duct run meets total equivalent length limits specified in the dryer manufacturer documentation.
