Continental Contitech 20042773 Cogged V-belt 4L 45in

Product Description

The CONTINENTAL CONTITECH 20042773 is a cogged fractional horsepower V-belt designed for light-duty power transmission in HVAC, agricultural, and general mechanical equipment. Built from high-traction rubber, this belt delivers reliable grip and reduced slippage across a range of drive configurations. The cogged profile lowers bending resistance, which improves efficiency and reduces heat buildup on smaller-diameter sheaves. With a 4L cross-section and a 45-inch outside length, it fits standard fractional horsepower drives encountered in residential and light commercial service work. HVAC technicians, equipment repair technicians, and mechanical contractors are the primary installers.

This belt is suited for fractional horsepower drive systems found in blower assemblies, fan drives, compressors, pumps, and general shop equipment. The 4L section is a common cross-section in residential HVAC air handlers and commercial ventilation units. The cogged design makes it well suited for drives with smaller pulley diameters where a conventional wrapped belt would flex poorly. The belt number 4L450 is the industry-standard designation for this size and profile.

Key Features

• Cogged profile reduces bending resistance on small-diameter sheaves
• High-traction rubber compound resists slippage under load
• Abrasion-resistant and ozone-resistant construction extends service life
• Wide operating temperature range: -40 degrees F to 284 degrees F (-40 C to 140 C)
• 4L section fits standard fractional horsepower sheaves
• Industry belt number 4L450 for straightforward cross-referencing

Compatibility

Designed as an OEM-style replacement for fractional horsepower V-belt drives using a 4L cross-section with a 45-inch outside length. Cross-references to industry belt number 4L450.

Installation Notes

Installation is performed by HVAC technicians or mechanical service technicians. Always de-energize and lock out the equipment before removing the old belt or installing the new one. Never pry or roll a V-belt onto a sheave under tension; loosen the drive motor mounting to provide slack. Verify sheave alignment and inspect sheave grooves for wear before installing a replacement belt.
