Continental Contitech 20042043 V-belt Section B 28 in B25

Product Description

The CONTINENTAL CONTITECH 20042043 is a Section B classical V-belt designed for industrial and HVAC drive applications requiring reliable, slip-resistant power transmission. Built with Wingprene rubber-impregnated fabric construction, this belt delivers oil resistance and flexibility across a wide operating temperature range of -40 degrees F to 284 degrees F. It carries the belt designation B25 and measures 28.0 inches in outside length with an internal length of 26.80 inches. Licensed HVAC technicians, millwrights, and mechanical contractors install this belt as a direct OEM-style or aftermarket replacement on belt-driven equipment including blowers, fans, compressors, and pumps.

This V-belt is suited for light commercial and residential HVAC systems, agricultural equipment, and general industrial machinery where a Section B cross-section drive belt is specified. The B25 designation corresponds to the industry-standard belt numbering system, making cross-referencing straightforward. The HY-T Matchmaker style is engineered for matched-set applications on multi-groove sheave drives, ensuring consistent length and tension when running in tandem with other belts of the same designation.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or mechanical service professional. Disconnect and lock out all power to the drive unit before removing the old belt or installing the new one. Adjust sheave spacing to allow belt seating without forcing, then set tension per the equipment manufacturer specification before restoring power. When replacing belts on a multi-groove drive, replace all belts as a matched set to ensure even load distribution.
