Continental Contitech 20042494 3VX Cogged V-belt 42.5 in

Product Description

The CONTINENTAL CONTITECH 20042494 is a 3VX section cogged V-belt designed for demanding drive applications in HVAC, industrial, and mechanical systems. Built with fiber-reinforced Wingprene rubber, this belt delivers reliable power transmission while resisting oil exposure that would degrade standard rubber belts. The cogged construction reduces bending resistance and heat buildup, allowing it to run efficiently on smaller-diameter sheaves. With a 42.5-inch outside length, it corresponds to the 3VX425 belt designation. HVAC technicians and mechanical contractors install this belt on fan drives, blower assemblies, and motor-to-equipment drive systems where wedge-section geometry is specified.

This belt is suited for residential and commercial HVAC fan and blower drive applications, as well as light industrial equipment that calls for a 3VX wedge-section cogged belt. The HY-T Wedge Matchmaker Cogged style is engineered for systems where matched sets or single-belt drives require consistent length and load performance. It is a direct replacement for any application specifying a 3VX425 belt number. Installers working on rooftop units, air handlers, and belt-driven blowers will find this a standard fitment option wherever the 3VX section is specified.

Key Features

• 3VX cogged section reduces heat buildup and improves flexibility on small-diameter sheaves
• Fiber-reinforced Wingprene rubber construction provides durability and dimensional stability
• Oil-resistant compound resists degradation in environments with incidental oil exposure
• 42.5-inch outside length matches the 3VX425 industry belt number designation
• HY-T Wedge Matchmaker Cogged style supports matched-set or single-belt drive configurations

Compatibility

Designed as an OEM-style replacement for any drive system specifying a 3VX425 cogged wedge V-belt. Confirm sheave groove profile and center-to-center distance against the 3VX section specification before installation.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical service professional. Disconnect and lock out all power to the drive system before removing the old belt or installing the new one. Adjust drive center distance to relieve tension before seating the belt — never roll or pry a V-belt over sheave flanges, as this can damage the cord structure. After installation, set tension per the drive manufacturer specification and verify alignment with a straightedge across both sheave faces.
