Continental Contitech 20042747 Cogged 4L V-belt 21 in

Product Description

The CONTINENTAL CONTITECH 20042747 is a cogged fractional horsepower V-belt designed for light-duty power transmission in HVAC, agricultural, and general industrial equipment. Built from high traction rubber, this 4L-section belt measures 21 inches in outside length with a 20-inch internal length. The cogged construction reduces flex fatigue, lowers heat buildup, and improves grip across the sheave surface. Rated for a maximum working temperature of 140 degrees C and a minimum of -40 degrees C, it handles wide temperature swings common in outdoor and mechanical room installations. HVAC technicians and equipment service pros install this belt as a direct OEM-style replacement on blowers, fans, and small-motor drive systems.

This belt fits residential and light commercial HVAC systems, evaporative coolers, ventilation fans, and fractional horsepower motor-drive applications where a 4L-section cogged belt is specified. The 4L210 designation is the standard industry cross-reference number for this belt. It is rated for abrasion resistance and ozone resistance, making it suitable for both indoor mechanical rooms and outdoor equipment enclosures exposed to UV and environmental stress. One belt is supplied per package.

Installation Notes

Installation is typically performed by HVAC technicians or equipment service technicians. Always disconnect and lock out power to the drive system before removing or installing the belt. Adjust sheave spacing to relieve tension before removal, then re-tension the new belt to the equipment manufacturer's specification after seating. Inspect sheave grooves for wear or misalignment before installing a replacement belt to avoid premature failure.
