4L Section V-Belt – Size Chart
How to Read a 4L V Belt Number
A 4L belt number identifies both the belt section and its nominal outside length. The 4L designation refers to the belt cross section, while the numbers that follow represent the outside length in tenths of an inch.
For example, 4L420 has an outside length of 42 inches. A 4L165 has an outside length of 16.5 inches.
Before ordering: Confirm the belt section and outside circumference of your existing belt. 4L belts and A section belts may share similar nominal cross section dimensions, but the length designations are not read the same way. Confirm the equipment and belt specifications before selecting a replacement.
