Continental Contitech 20042505 Cogged V-belt 3VX 80 in

Product Description

The CONTINENTAL CONTITECH 20042505 is a cogged 3VX section V-belt designed for power transmission applications in HVAC, industrial, and commercial equipment. Built from fiber reinforced Wingprene rubber, this belt delivers reliable torque transfer while resisting heat, flex fatigue, and oil exposure. The cogged construction reduces bending resistance, which improves efficiency and extends belt life compared to standard wrapped belts. With an outside length of 80 inches, it fits a range of driven equipment where 3VX cross-section geometry is specified. Licensed HVAC technicians and mechanical contractors are the typical installers for this belt type.

This 3VX cogged V-belt is suited for residential and commercial HVAC applications, as well as light industrial drives where oil-resistant, high-flex belts are required. The 3VX section is a standard wedge profile used on HVAC air handlers, blowers, compressors, and similar rotating equipment. The HY-T Wedge Matchmaker cogged style designation indicates it is engineered for matchable drive sets, supporting single or matched-belt configurations on sheave-driven systems where consistent tension across multiple belts is critical.

Key Features

• Cogged construction reduces bending resistance and improves power transmission efficiency
• Fiber reinforced Wingprene rubber construction provides durability and flex resistance
• Oil resistant formulation suitable for environments with incidental oil or grease exposure
• 3VX section geometry conforms to standard wedge V-belt sheave profiles
• HY-T Wedge Matchmaker style supports matched-belt drive applications
• 80 inch outside length suits a wide range of commercial and industrial drive configurations

Compatibility

Designed as a direct replacement for 3VX section cogged V-belts with an outside length of 80 inches, also identified by belt number 3VX800. Verify sheave groove profile and drive specifications before installation.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disengage and lock out all power to the drive system before removing or installing the belt. Never force a belt onto a sheave with a pry bar, as this can damage the belt cords. After installation, check belt tension and sheave alignment per the equipment manufacturer's specifications before returning the system to service.
