Continental Contitech 20042777 Cogged V-belt 4L 49 in

Product Description

The CONTINENTAL CONTITECH 20042777 is a fractional horsepower cogged V-belt designed for light-duty power transmission in HVAC, refrigeration, and general mechanical equipment. Built from high-traction rubber, this belt features a cogged (notched) construction that increases flexibility, reduces heat buildup, and improves grip on sheaves compared to standard wrapped belts. It carries a 4L section designation with a 49.0-inch outside length and a 48.0-inch internal length. HVAC technicians and mechanical contractors use this belt as a direct drive or blower belt in air handling and fan applications requiring a fractional horsepower belt drive.

This belt is suited for residential and light commercial HVAC systems, portable fans, small compressors, and other fractional horsepower equipment that call for a 4L-section belt. The 4L490 belt number is the standard cross-reference designation used across the industry to identify this size. It is rated for operation across a wide temperature range, from -40 degrees F to approximately 284 degrees F, making it viable in both cold-weather and high-ambient installations. Technicians replacing worn or glazed drive belts during routine maintenance or equipment repair will find this a straightforward drop-in fit for any drive system specifying the 4L490 profile.

Key Features

• Cogged (notched) construction reduces bending resistance and extends belt life on small-diameter sheaves
• High-traction rubber compound improves power transfer and reduces slippage
• Abrasion-resistant and ozone-resistant materials for extended service life in mechanical equipment rooms
• Wide operating temperature range: -40 degrees F to 284 degrees F
• 4L section with 49.0-inch outside length and 48.0-inch internal length
• Industry-standard 4L490 belt number for easy cross-referencing

Compatibility

Designed as an OEM-style replacement for fractional horsepower belt drive systems specifying a 4L-section V-belt with a 4L490 belt number designation.

Installation Notes

Installation is typically performed by HVAC technicians or mechanical contractors. Disconnect and lock out power to the equipment before removing the old belt or accessing the drive sheaves. Adjust sheave spacing to allow belt installation without forcing the belt over the sheave rim, then re-tension according to the equipment manufacturer specifications. Inspect sheave grooves for wear or misalignment before installing a new belt, as worn grooves accelerate belt degradation.
