Continental Contitech 20042486 3VX Cogged V-belt 28 in

Product Description

The CONTINENTAL CONTITECH 20042486 is a 3VX section cogged V-belt designed for power transmission in HVAC, industrial, and mechanical drive applications. Manufactured under the HY-T Wedge Matchmaker Cogged designation, it features a fiber-reinforced Wingprene rubber construction that delivers flexibility, heat resistance, and durability under continuous load. The cogged profile reduces bending resistance for improved efficiency on smaller-diameter sheaves. The outside length is 28 inches, corresponding to the standard belt number 3VX280. This belt is installed by HVAC technicians, millwrights, and mechanical contractors performing drive system maintenance or replacement.

The 3VX280 is suited for residential and light commercial HVAC units, fan drives, compressor drives, and general power transmission equipment that uses 3VX-section sheaves. The cogged design allows it to run on the same drives as standard wrapped belts while generating less heat and flex fatigue. It is commonly found in air handlers, condensing units, blower assemblies, and other belt-driven rotating equipment requiring a narrow, high-efficiency wedge profile.

Key Features

• 3VX section cogged profile reduces bending stress on small-diameter sheaves
• Fiber-reinforced Wingprene rubber construction for heat and oil resistance
• HY-T Wedge Matchmaker Cogged style for matched-set compatibility in multi-belt drives
• 28-inch outside length (3VX280 standard designation)
• Direct replacement for standard 3VX section wrapped and cogged belts of equivalent length

Compatibility

Designed as an OEM-style replacement for belt-driven HVAC and mechanical equipment requiring a 3VX section cogged V-belt with a 28-inch outside length.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical contractor. De-energize the unit and lock out the power supply before removing any belt guards or accessing the drive sheaves. Adjust sheave center distance to allow belt seating without forcing, then tension to manufacturer specifications before restoring power. Inspect sheaves for wear, misalignment, and debris before installing the new belt.
