Continental Contitech 20042105 V-belt Section B 90 in B87

Product Description

The CONTINENTAL CONTITECH 20042105 is a Section B classical V-belt designed for power transmission in industrial, HVAC, and mechanical drive applications. Built with Wingprene rubber-impregnated fabric construction, this belt delivers reliable flexibility and resistance across a wide temperature range, from -40 degrees C to 140 degrees C. It carries the B87 belt designation, corresponding to a 90.0 inch outside length and an 88.80 inch internal length. Licensed HVAC technicians, millwrights, and mechanical contractors specify this belt for belt-drive systems on air handlers, fans, compressors, and other rotating equipment.

This belt fits Section B drive applications in both residential and light commercial systems. The HY-T Matchmaker style is engineered for matched-set use on multi-groove sheaves, keeping belt tension balanced across the drive. Typical install scenarios include belt replacement on belt-drive air handlers, centrifugal fans, pump drives, and industrial machinery where a B-section groove profile is specified. It ships individually and is also suitable for use as a single-drive replacement on standard two-groove or single-groove sheave setups.

Key Features

• Section B profile with 90.0 inch outside length and 88.80 inch internal length
• Wingprene rubber-impregnated fabric construction for oil and heat resistance
• Operating temperature range: -40 degrees C to 140 degrees C
• HY-T Matchmaker style — suitable for matched-set multi-groove sheave drives
• B87 belt designation for straightforward cross-reference and replacement ordering

Compatibility

Designed as a direct replacement for any drive system calling for a B87 or Section B classical V-belt with a 90.0 inch outside length. Verify sheave groove profile matches Section B specifications before installation.

Installation Notes

Installation should be performed by a qualified technician. Disconnect and lock out all power to the drive system before removing the old belt or fitting the new one. Never force a belt onto a sheave using a screwdriver or pry bar, as this can damage the belt cords and shorten service life. Align sheaves within manufacturer tolerances and verify tension per the drive design specifications after installation.
