Diversitech t-408 Fin Comb Coil Tool

Product Description

The DIVERSITECH t-408 is a fin comb designed to straighten bent or damaged fins on air conditioning and heat pump coils. Bent fins restrict airflow across the coil, reducing system efficiency and heat transfer. This tool allows HVAC technicians to restore fin alignment without damaging the coil tubing underneath. It is a standard service tool kept on most residential and light commercial HVAC service vehicles.

The t-408 fin comb is used during routine maintenance calls, post-installation inspections, and service visits where coil fin damage is found on evaporator or condenser coils. It is appropriate for residential split systems and light commercial packaged units where aluminum fin coils are standard.

Key Features

• Straightens bent and crushed fins on evaporator and condenser coils
• Restores airflow and heat transfer efficiency after fin damage
• Designed for use on aluminum fin coils common in residential and light commercial HVAC equipment
• Compact tool suitable for field service use

Compatibility

Designed for use on aluminum fin coils found in residential and light commercial air conditioning, heat pump, and refrigeration equipment. Specific fin spacing compatibility was not provided in the available product data.

Installation Notes

Disconnect and lock out power to the unit before working near coil fins. Insert the fin comb carefully at the base of the damaged fin section and draw it straight through in one smooth motion to avoid additional bending or tube damage. HVAC technicians should follow standard EPA and OSHA safety guidelines when servicing refrigerant-containing equipment. Gloves are recommended, as coil fins have sharp edges.
