Continental Contitech 20042751 Cogged 4L V-belt 25 in

Product Description

The CONTINENTAL CONTITECH 20042751 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications in HVAC, refrigeration, and general mechanical systems. Built from high-traction rubber, this belt delivers reliable grip and reduced slippage across a wide operating temperature range of -40 degrees F to 284 degrees F. The cogged profile lowers bending resistance, improves flexibility around smaller sheaves, and reduces heat buildup during operation. At 25 inches outside length and 24 inches internal length, this belt fits standard 4L-section drives. HVAC technicians and mechanical service pros install this belt as a direct OEM-style replacement or new installation component.

The 4L-section cogged V-belt is commonly used in residential and light commercial HVAC equipment including air handlers, condenser fan assemblies, blower drives, and belt-driven compressor setups. The fractional horsepower rating makes it well suited for smaller motor-to-sheave applications where precise belt sizing is critical to system efficiency and noise control. Abrasion-resistant and ozone-resistant construction extends service life in outdoor or mechanically demanding environments.

Key Features

• Cogged design reduces bending resistance and heat buildup on small-diameter sheaves
• High-traction rubber construction for reduced slippage and consistent power transfer
• Abrasion-resistant and ozone-resistant for indoor and outdoor service environments
• Wide operating range: -40 degrees F to 284 degrees F (140 degrees C max)
• Belt Number 4L250 for cross-reference and ordering verification
• Fractional horsepower V-belt profile fits standard 4L-section sheaves

Compatibility

Designed as an OEM-style replacement for equipment using standard 4L-section fractional horsepower V-belt drives with a 25-inch outside length. Cross-references to belt number 4L250.

Installation Notes

Installation is typically performed by HVAC technicians or mechanical service professionals. Always disconnect and lock out power to the equipment before removing or installing drive belts. Use a belt tension gauge when available to set proper deflection, and do not pry belts over sheave flanges, as this can damage the belt cord. Inspect sheave grooves for wear or misalignment before installing a new belt.
