Continental Contitech 20042753 Cogged V-belt 4L 27 in

Product Description

The CONTINENTAL CONTITECH 20042753 is a fractional horsepower cogged V-belt designed for light-duty power transmission applications in HVAC, refrigeration, and general mechanical equipment. Built from high traction rubber, this belt features a cogged (notched) construction that increases flexibility, reduces heat buildup, and improves grip on smaller-diameter sheaves. The 4L section designation indicates a fractional horsepower belt profile with a 27-inch outside length and a 26-inch internal length. It is rated for operation from -40 degrees C up to 140 degrees C, making it suitable for equipment that cycles through wide temperature ranges.

This belt is commonly used in residential and light commercial HVAC systems, fan drives, blower assemblies, and small motor-driven equipment where a 4L fractional horsepower belt profile is specified. Typical installations include condenser fan drives, evaporator blower assemblies, and other belt-driven components requiring a cogged V-belt in the 4L section. The cogged design also makes it a direct performance upgrade over standard smooth V-belts in the same section and length.

Key Features

• Cogged (notched) construction increases flexibility and reduces operating temperature on small-diameter sheaves
• High traction rubber compound for reliable power transfer
• Abrasion resistant and ozone resistant for extended service life in outdoor and mechanical environments
• Wide operating temperature range: -40 degrees C to 140 degrees C
• 4L section profile with 27-inch outside length and 26-inch internal length
• Belt number 4L270 for cross-reference and replacement sourcing

Compatibility

Designed as an OEM-style replacement fractional horsepower cogged V-belt for equipment requiring a 4L section belt with a 27-inch outside length. Cross-references to belt number 4L270.

Installation Notes

Installation is typically performed by HVAC technicians or mechanical service professionals. Always disconnect and lock out power to the equipment before removing or installing drive belts. Proper belt tension should be set per the equipment manufacturer specifications to avoid premature wear or slippage. Do not apply belt dressing compounds to cogged V-belts, as these can degrade the rubber compound and reduce service life.
