Continental Contitech 20042064 V-belt Section B 49 in B46

Product Description

The CONTINENTAL CONTITECH 20042064 is a Section B V-belt designed for power transmission drives in HVAC, industrial, and mechanical equipment applications. Built from Wingprene rubber-impregnated fabric, this belt delivers reliable flex and wear resistance across a wide operating temperature range of -40 degrees F to 284 degrees F (equivalent to -40 degrees C to 140 degrees C). With a 49.0-inch outside length and a 47.80-inch internal length, this belt carries the standard designation B46. It is sold individually and suits service technicians and mechanical contractors who maintain belt-driven blower assemblies, fans, and light industrial machinery.

This V-belt is suited for residential and light commercial HVAC systems, refrigeration equipment, and general-purpose mechanical drives that use a standard Section B sheave profile. The HY-T Matchmaker construction is engineered for matched-set drive systems, making it appropriate for multi-belt drive configurations where consistent belt length and cross-section geometry are critical to balanced load distribution. Technicians working on air handling units, furnace blower drives, condenser fan drives, and similar rotating equipment will find this belt dimensionally compatible with standard Section B pulleys.

Key Features

• Wingprene rubber-impregnated fabric construction resists heat, oil, and flex fatigue
• Section B profile fits standard B-section sheaves and pulley grooves
• 49.0-inch outside length with 47.80-inch internal length for accurate fitment
• HY-T Matchmaker design supports matched-set multi-belt drive installations
• Wide operating temperature range: -40 degrees C to 140 degrees C (-40 degrees F to 284 degrees F)
• Sold as a single belt (package quantity of 1)

Compatibility

Designed as an OEM-style replacement V-belt for Section B drive systems. This belt carries the standard industry designation B46, making it a direct dimensional replacement for any B46-spec belt position in HVAC blower drives, fan drives, and general mechanical power transmission applications using a Section B sheave.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical service professional. Always disconnect and lock out electrical power to the equipment before removing the old belt or installing a replacement. Loosen the motor mounting hardware to relieve tension before removing the belt; never force a belt over a sheave under tension, as this can damage the belt cords and reduce service life. After installation, adjust drive tension per the equipment manufacturer specifications and verify sheave alignment before restoring power.
