Continental Contitech 20042706 Cogged V-belt 3L 38in

Product Description

The CONTINENTAL CONTITECH 20042706 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications across HVAC, agricultural, and general industrial equipment. Built from high-traction rubber, this belt carries the 3L cross-section profile with a 38.0-inch outside length and a 37.30-inch internal length. The cogged construction reduces flex resistance, which improves efficiency and extends belt life on smaller-diameter sheaves. It resists abrasion and ozone degradation and is rated for a maximum working temperature of 140 degrees C and a minimum of -40 degrees C, making it suitable for both indoor mechanical rooms and outdoor equipment installations.

This belt is used in fractional horsepower drive systems found in residential and light commercial HVAC units, blower assemblies, fans, pumps, and small compressor drives. The 3L section is a common fractional horsepower profile specified by OEM equipment manufacturers where a narrow, cogged belt is required for compact drive configurations. HVAC technicians, mechanical contractors, and equipment maintenance professionals typically encounter this belt in belt-driven blower and fan applications. The belt number designation is 3L380.

Key Features

• Cogged design reduces bending resistance for improved efficiency on small-diameter sheaves
• High-traction rubber construction for reliable grip and power transfer
• Abrasion-resistant and ozone-resistant for extended service life
• Wide operating temperature range: -40 degrees C to 140 degrees C
• 3L fractional horsepower section profile
• 38.0-inch outside length with 37.30-inch internal length

Compatibility

Designed as an OEM-style replacement for fractional horsepower belt-driven systems requiring a 3L-section cogged V-belt with a 38.0-inch outside length. Cross-reference belt number 3L380 when sourcing replacements.

Installation Notes

Installation is typically performed by HVAC technicians or mechanical maintenance professionals. Always disconnect and lock out power to the unit before removing the belt guard or accessing the drive assembly. Do not pry the belt onto a sheave with tools; adjust the drive component to relieve tension first, seat the belt, then set tension according to the equipment manufacturer specification. Inspect sheave grooves for wear or misalignment before installing a new belt to avoid premature failure.
