Continental Contitech 20042705 Cogged V-belt 3L 37in

Product Description

The CONTINENTAL CONTITECH 20042705 is a cogged fractional horsepower V-belt designed for light-duty power transmission applications in HVAC, refrigeration, and general mechanical equipment. Built from high-traction rubber, this 3L-section belt delivers reliable grip and flex across a wide operating temperature range, from -40 degrees F to 284 degrees F (140 degrees C). The cogged construction reduces bending resistance, improving efficiency and reducing heat buildup on smaller-diameter sheaves. It carries the belt number 3L370, referencing its 37-inch outside length and fractional horsepower section designation.

This belt is suited for residential and light commercial HVAC systems, blower assemblies, small compressors, and other equipment using fractional horsepower drives with 3L-section sheaves. The 3L profile is a standard fractional horsepower size commonly found in packaged units, air handlers, and auxiliary fan drives. HVAC technicians and mechanical service pros install this belt as a direct OEM-style replacement during scheduled maintenance or after belt failure. Its abrasion and ozone resistance make it a durable choice for both indoor and outdoor equipment.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical service professional. Disconnect and lock out all power to the equipment before removing the old belt or accessing the drive assembly. Never pry or force a belt over sheave flanges; always release drive tension using the proper adjustment mechanism before seating the new belt. Inspect sheaves for wear, misalignment, and debris before installing the replacement belt.
