Continental Contitech 20042686 3L Cogged V-belt 18 in

Product Description

The CONTINENTAL CONTITECH 20042686 is a cogged fractional horsepower V-belt designed for light-duty power transmission applications. Constructed from high traction rubber, this 3L-section belt measures 18 inches in outside length and 17.30 inches in internal length. The cogged profile reduces bending resistance and heat buildup, which extends belt life and improves efficiency on smaller sheaves. It is rated for operation between -40 degrees C and 140 degrees C, making it suitable for year-round service in both indoor and outdoor equipment. Licensed HVAC technicians, equipment mechanics, and service pros install this belt as a direct replacement on fractional horsepower drives.

This belt is suited for residential and light commercial applications where fractional horsepower drives are common, including HVAC air handlers, furnace blowers, small compressors, and other belt-driven equipment using 3L-section pulleys. The belt number 3L180 is the standard industry designation and can be cross-referenced directly when sourcing a replacement. Its abrasion-resistant and ozone-resistant construction makes it appropriate for both indoor mechanical rooms and exposed outdoor unit installations.

Designed as a replacement for fractional horsepower belt-driven equipment using 3L-section V-belt pulleys. Cross-references to belt number 3L180 for direct sourcing and replacement.

Installation Notes

Power down and lock out the equipment before removing the old belt or installing the new one. Verify sheave alignment and inspect pulley grooves for wear before installation. Use proper belt tension per the equipment manufacturer's specifications — do not pry the belt over a sheave with a tool, as this can damage the cord structure. A qualified technician should confirm correct belt section and length before commissioning the drive.
