Continental Contitech 20042719 Cogged V-belt 3L 50in

Product Description

The CONTINENTAL CONTITECH 20042719 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications in HVAC, agricultural, and general industrial equipment. Built from high traction rubber, this belt features a cogged construction that reduces heat buildup and flexing resistance, improving efficiency on smaller-diameter sheaves. The 3L section profile has a 50.0 inch outside length and an internal length of 49.30 inches. Rated for operation from -40 degrees F to 284 degrees F (140 degrees C), it handles a wide range of operating environments. Weighing 0.16 pounds, it is a direct drop-in replacement for standard 3L500 belt applications.

The 3L section cogged V-belt is commonly used in residential and light commercial HVAC blower assemblies, small compressors, fans, and shop equipment where fractional horsepower drives are specified. Its cogged design allows tighter bend radii compared to a standard wrapped belt, making it well-suited for drives with smaller-diameter pulleys. The abrasion-resistant and ozone-resistant compound extends service life in both indoor and outdoor equipment. Technicians servicing air handlers, condenser fans, or belt-drive blowers will recognize the 3L500 designation as a widely used size across multiple equipment types.

Key Features

• Cogged construction reduces flex resistance and heat buildup on small-diameter sheaves
• High traction rubber compound for reliable grip and power transfer
• Abrasion resistant and ozone resistant for extended service life
• Wide operating temperature range: -40 degrees C to 140 degrees C
• Standard 3L500 belt number for easy cross-reference and replacement

Compatibility

Designed as an OEM-style replacement for fractional horsepower drives using the standard 3L section V-belt profile with a 50.0 inch outside length, also referenced by belt number 3L500.

Installation Notes

Belt replacement on HVAC blowers and fan assemblies should be performed with the unit fully de-energized and locked out per OSHA lockout/tagout procedures. Remove tension from the drive by adjusting the motor mount before removing the old belt; never force a belt over a sheave flange. Check sheave alignment and inspect for pulley wear before installing the replacement belt. After installation, verify proper belt tension per the equipment manufacturer's specification before returning the unit to service.
