Continental Contitech 20042704 Cogged V-belt 3L 36 in

Product Description

The CONTINENTAL CONTITECH 20042704 is a fractional horsepower cogged V-belt designed for light-duty power transmission in HVAC, refrigeration, and general industrial equipment. Built from high-traction rubber, the cogged profile reduces bending resistance and heat buildup, improving efficiency and belt life in smaller-diameter pulley applications. It carries a 3L cross-section designation and an outside length of 36 inches, with a belt number of 3L360 and an internal length of 35.30 inches. HVAC technicians and equipment service pros install this belt on blowers, fans, and fractional horsepower drive systems. It is rated for use from -40 degrees C up to 140 degrees C, making it suitable for demanding seasonal operating conditions.

This belt fits fractional horsepower drive applications common in residential and light commercial HVAC systems, including belt-drive blower assemblies, evaporative coolers, and small fan units. The 3L section is a standard fractional horsepower profile widely used across OEM and aftermarket blower and fan drive configurations. It is sold individually and is a direct form-factor replacement for worn or cracked 3L360 belts identified during routine maintenance or equipment inspection.

Key Features

• Cogged design reduces bending resistance and heat buildup on small-diameter pulleys
• High-traction rubber construction 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
• 3L360 belt number with 36-inch outside length and 35.30-inch internal length
• Fractional horsepower V-belt profile for light-duty drive systems

Compatibility

Designed as an OEM-style replacement for fractional horsepower belt-drive systems using a 3L section V-belt with a 36-inch outside length (belt number 3L360).

Installation Notes

Shut down and lock out all power to the equipment before removing the old belt or installing the new one. HVAC technicians should verify pulley alignment and sheave condition prior to installation, as misalignment accelerates belt wear. Use a belt tension gauge when available to set proper tension without overtightening, which can damage bearings. Follow equipment manufacturer guidelines and applicable OSHA lockout/tagout procedures throughout the service process.
