Continental Contitech 20042687 Cogged V-belt 3L 19 in

Product Description

The CONTINENTAL CONTITECH 20042687 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications in HVAC, refrigeration, and general equipment service. Manufactured from high traction rubber, this belt features a cogged profile that increases flexibility, reduces heat buildup, and improves grip on smaller-diameter sheaves. It carries a 3L belt section designation with a 19.0 inch outside length and an 18.30 inch internal length. The cogged construction allows it to bend more easily around compact pulley systems while maintaining consistent power transfer under varying load conditions. Licensed HVAC technicians and equipment service professionals are the primary installers of this belt type.

This belt is suited for residential and light commercial HVAC units, fractional horsepower motors, blower assemblies, and auxiliary equipment drives where a 3L section belt is specified. The 3L190 belt number is the standard industry cross-reference designation for this size. It is rated for operating temperatures ranging from -40 degrees C to 140 degrees C, making it appropriate for equipment installed in both cold-climate and high-heat environments. Its abrasion-resistant and ozone-resistant properties extend service life in demanding conditions including outdoor or partially exposed installations.

Installation Notes

Belt replacement on HVAC and blower assemblies should be performed by a qualified technician. Power down and lock out the unit before removing the belt guard or accessing the drive assembly. Inspect the sheaves for wear or misalignment before installing the new belt, and never use tools to force the belt over a pulley flange. Verify the replacement belt number matches the equipment nameplate specification before installation.
