Continental Contitech 20042502 3VX Cogged V-belt 67in

Product Description

The CONTINENTAL CONTITECH 20042502 is a cogged V-belt in the 3VX section, designed for high-efficiency power transmission in HVAC, industrial, and mechanical drive applications. Built from fiber-reinforced Wingprene rubber, this belt delivers oil resistance and durability under demanding operating conditions. The cogged construction reduces bending resistance and heat buildup, making it well-suited for variable-speed and high-load drive systems. With a 67-inch outside length and sold under the belt number 3VX670, this belt follows the HY-T Wedge Matchmaker Cogged style specification. Qualified technicians and millwrights install this component as a direct replacement or new-installation drive belt on matched sheave and pulley systems.

This belt is applicable to HVAC blower drives, refrigeration condensing unit fan drives, commercial rooftop unit drives, and general industrial machinery requiring a 3VX-section cogged belt. The 3VX profile is commonly found in fractional to medium-horsepower drives where space constraints call for a narrow, high-capacity belt. The cogged design improves grip and flex on smaller-diameter sheaves and is compatible with standard 3VX-profile grooved sheaves and pulleys used across residential and light commercial mechanical systems.

Key Features

• 3VX cogged section profile reduces flex fatigue and heat generation on smaller sheaves
• Fiber-reinforced Wingprene rubber construction provides oil resistance and long service life
• HY-T Wedge Matchmaker Cogged style for use in matched-set or single-belt drive configurations
• 67-inch outside length (belt number 3VX670) for precise sheave-to-sheave span fitment
• Oil-resistant compound suitable for environments with incidental petroleum exposure

Compatibility

Designed as a direct replacement for 3VX-section cogged V-belt applications requiring a 67-inch outside length. Fits standard 3VX-profile grooved sheaves. Confirm outside length, section profile, and sheave groove angle before installation.

Installation Notes

Installation should be performed by a qualified HVAC technician, millwright, or mechanical contractor. De-energize and lock out the drive motor before removing the old belt or installing the new one. Never force a belt over a sheave flange; always adjust the center distance to allow slack for proper seating. After installation, verify belt tension and alignment per the equipment manufacturer specifications before restoring power.
