Continental Contitech 20042689 Cogged V-belt 3L 21 in

Product Description

The CONTINENTAL CONTITECH 20042689 is a fractional horsepower cogged V-belt in the 3L section, also identified by belt number 3L210. It features a high traction rubber construction with a 21.0-inch outside length and an internal length of 20.30 inches. The cogged profile reduces bending resistance, improving flexibility and heat dissipation compared to a standard wrapped belt. This belt is rated for operating temperatures from -40 degrees C up to 140 degrees C and carries abrasion-resistant and ozone-resistant properties. Licensed HVAC technicians, equipment mechanics, and pool equipment service pros commonly specify this belt for light-duty drive applications.

The 3L210 is suited for fractional horsepower drives found in residential and light commercial equipment, including blower assemblies, small compressor drives, and pool pump or filtration units. The 3L section is a common fractional horsepower profile used across a wide range of OEM and aftermarket drive setups. Its cogged design allows it to run on smaller-diameter sheaves while maintaining grip and reducing slippage under variable load conditions.

Key Features

• Cogged belt profile reduces bending resistance and improves heat dissipation on small-diameter sheaves
• High traction rubber construction provides consistent grip under variable load
• Abrasion-resistant and ozone-resistant compound extends service life in outdoor and mechanical room environments
• Wide operating temperature range: -40 degrees C to 140 degrees C
• 3L section fractional horsepower profile with 21.0-inch outside length and 20.30-inch internal length

Compatibility

Designed as a direct replacement for 3L210 fractional horsepower V-belt applications in residential and light commercial drive systems requiring a 3L section belt with a 21.0-inch outside length.

Installation Notes

Belt replacement should be performed by a qualified technician. Always de-energize and lock out the equipment before removing the drive cover or guard. Inspect sheaves for wear, misalignment, and debris before installing the new belt. Do not pry the belt over sheave flanges; loosen the drive component to create slack for proper seating.
