Continental Contitech 20042506 3VX Cogged V-belt 85 in

Product Description

The CONTINENTAL CONTITECH 20042506 is a cogged V-belt designed for power transmission applications in HVAC, industrial, and mechanical drive systems. Built from fiber-reinforced Wingprene rubber, this belt belongs to the 3VX section and carries the belt designation 3VX850, indicating an 85-inch outside length. The cogged construction reduces bending resistance, allows operation on smaller sheave diameters, and improves heat dissipation compared to standard wrapped belts. Oil-resistant compound helps the belt hold up in environments where fluid exposure is a concern. HVAC technicians and mechanical contractors are the typical installers.

This belt is suited for use in commercial and residential HVAC units, refrigeration systems, compressors, fans, blowers, and general industrial drives where a 3VX section cogged belt is specified. The HY-T Wedge Matchmaker Cogged style allows matched-set use in multi-belt drive configurations, making it compatible with other belts of the same designation for balanced load sharing. It is sold individually and is appropriate for single or multi-groove sheave arrangements that call for a 3VX cross-section.

Key Features

• 3VX section cogged profile reduces flex fatigue and heat buildup on smaller sheaves
• Fiber-reinforced Wingprene rubber construction provides durability and oil resistance
• HY-T Wedge Matchmaker Cogged style supports matched-set multi-belt drive applications
• 85-inch outside length suits a wide range of drive configurations in HVAC and industrial equipment
• Oil-resistant compound extends service life in environments with incidental fluid exposure

Compatibility

Designed as an OEM-style replacement for drive systems requiring a 3VX section cogged V-belt with an 85-inch outside length, also identified by belt number 3VX850.

Installation Notes

Belt replacement is typically performed by HVAC technicians or mechanical contractors. Disconnect and lock out electrical power to the drive unit before removing the old belt or installing the new one. Never pry a belt over sheave flanges using a screwdriver or sharp tool, as this can damage the belt cords. After installation, verify belt tension and sheave alignment per the equipment manufacturer's specifications before returning the unit to service.
