Bando 4L330 Fhp V-belt 4L Section 33in Ol 1/2in Wide

Product Description

The BANDO 4L330 is a fractional horsepower (FHP) V-belt designed for light-duty power transmission in HVAC, agricultural, and general industrial applications. Built to 4L section standards, it measures 33 inches in outside length and 0.5 inches in width, with a thickness of 0.31 inches. Constructed from rubber with ozone-resistant properties, this belt maintains flexibility and integrity in environments where UV and ozone exposure can degrade standard belts. The 4L330 meets RMA standards and is installed by HVAC technicians, maintenance mechanics, and equipment service professionals across a wide range of belt-drive systems.

This belt is suited for residential and light commercial belt-drive applications, including furnace blowers, air handlers, fans, and small motor-driven equipment. The 4L section profile is a standard fractional horsepower designation used in a broad range of OEM and replacement drive configurations. At 0.199 pounds, it is lightweight and straightforward to carry and install on job sites. Technicians replacing worn or cracked drive belts on blower assemblies will find this a direct fit for 4L330 applications.

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. Do not force the belt over sheave flanges; relieve tension by adjusting the motor mount before seating the belt, then re-tension per the equipment manufacturer specifications. Inspect sheaves for wear or misalignment before installing a new belt.
