Continental Contitech 20042778 Cogged V-belt 4L 50 in

Product Description

The CONTINENTAL CONTITECH 20042778 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications in HVAC, refrigeration, and general mechanical equipment. Manufactured from high traction rubber, this belt carries the belt number 4L500, indicating a 4L section profile with a 50-inch outside length and a 49-inch internal length. The cogged underside reduces bending resistance, improves flexibility around smaller sheaves, and helps dissipate heat during operation. It is rated for a maximum working temperature of 140 degrees C and a minimum working temperature of -40 degrees C, making it suitable for demanding indoor and outdoor service environments.

This belt is used in residential and light commercial HVAC systems, fans, blowers, compressors, and other belt-driven equipment that accepts a 4L fractional horsepower profile. The 4L section is a common standard in furnace blower assemblies, condenser fan units, and small motor-driven equipment. Technicians replacing worn, cracked, or glazed drive belts will find this a direct-profile match for 4L500 belt applications. It is sold individually and is appropriate for single-belt drive configurations.

Key Features

• Cogged design reduces bending resistance and runs cooler on small-diameter sheaves
• High traction rubber construction for reliable power transfer
• Abrasion resistant and ozone resistant for extended service life
• Wide temperature range: -40 degrees C to 140 degrees C
• 4L500 belt number: 4L section, 50-inch outside length, 49-inch internal length
• Fractional horsepower V-belt profile suited for common HVAC and blower drives

Compatibility

Designed as an OEM-style replacement for belt-driven equipment requiring a 4L section fractional horsepower V-belt with a 50-inch outside length, cross-referenced as belt number 4L500.

Installation Notes

Belt replacement is typically performed by HVAC technicians or mechanical service professionals. Disconnect and lock out power to the unit before removing the old belt or accessing the drive assembly. Inspect sheaves for wear, misalignment, and debris before installing the new belt. Do not pry or force the belt over sheave flanges; adjust the drive to relieve tension, seat the belt, then re-tension according to the equipment manufacturer's specification.
