Continental Contitech 20042046 V-belt Section B B28 31 in

Product Description

The CONTINENTAL CONTITECH 20042046 is a Section B V-belt designed for power transmission in HVAC, industrial, and mechanical drive applications. Built with Wingprene rubber-impregnated fabric construction, this belt offers resistance to heat, oil, and environmental exposure. It carries the B28 belt designation and measures 31.0 inches in outside length with an internal length of 29.80 inches. The HY-T Matchmaker profile ensures consistent cross-section geometry, making it a dependable replacement for matched or single-belt drives. Licensed HVAC technicians, millwrights, and mechanical contractors are the primary installers for this type of drive component.

This V-belt is suited for residential and light commercial HVAC blower drives, refrigeration condenser fan drives, and general-purpose industrial machinery using Section B sheaves and pulleys. The wide working temperature range of -40 degrees C to 140 degrees C makes it appropriate for both indoor and outdoor mechanical drive systems subject to seasonal temperature extremes. It is sold individually and is compatible with standard Section B grooved sheaves and V-belt drive systems requiring a B28 belt.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing any belt. Never pry a V-belt over a sheave with tools that could damage the belt cords or groove surfaces — always reduce center distance to allow slack for proper seating. Verify sheave alignment and tension according to the equipment manufacturer's drive specifications before returning the system to service.
