TEMSONE 16-Pass 1/2" Transmission Cooler — -8AN Aftercooler, Compact Aluminum Tube-and-Fin

TEMSONE 16-pass 1/2" transmission cooler is a compact aluminum tube-and-fin heat exchanger designed to lower fluid temperature for transmissions and air compressors.

This high-efficiency cooler fits -8AN (1/2") transmission cooler lines and serves as an inline oil or aftercooler to help control operating temperatures. Built from corrosion-resistant aluminum with a 16-pass tube layout, it is intended for vehicles and compressor systems where space is limited but reliable heat rejection is required. Check hose diameter and installation clearance before ordering to ensure proper fitment.

How does the 16-pass design improve cooling performance?

The multiple passes increase fluid contact time and surface area, promoting greater heat transfer between the internal oil and the external air. The tube-and-fin arrangement directs flow through successive channels so the oil sheds heat more effectively than single-pass cores.

• 16 internal passes for extended fluid residence time
• Tube-and-fin geometry increases external surface area
• Aluminum body conducts heat rapidly to ambient air
• Coated finish for improved resistance to corrosion

Will this cooler connect to my transmission or compressor lines?

This unit is made for -8AN (1/2") fittings and works with standard 1/2" transmission cooler hoses or AN adapters. Confirm the diameter of your existing lines and that you have several inches of clearance for mounting and hose routing.

• Direct compatibility with -8AN (1/2") lines
• Simple hose or AN adapter hookup for retrofit installs
• Compact footprint suits tight engine bays or compressor racks
• Mounting tabs allow secure attachment to chassis or bracket

What materials and longevity features are included?

The cooler is constructed from durable aluminum for strong thermal conductivity and light weight. A protective coating reduces the chance of surface corrosion from road salts, water, and atmospheric exposure, prolonging service life.

• Full aluminum construction—lightweight and thermally efficient
• Surface coating for enhanced corrosion resistance
• Robust tube-and-fin assembly designed for vibration resistance
• Backed by one year of product quality support from TEMSONE

How will installing this cooler affect my vehicle or compressor?

Adding a dedicated transmission or aftercooler helps maintain a more stable fluid temperature under load, which can reduce heat-related stress on components. While results depend on application and installation quality, users typically see lower peak temperatures and improved operating consistency when the cooler is properly integrated.

• Helps lower peak fluid temperatures under heavy duty or towing
• May reduce thermal wear on transmission and compressor parts
• Supports more consistent fluid performance during long runs
• Requires proper hose routing and secure mounting for best results

Who is this for: The TEMSONE 16-pass 1/2" cooler is ideal for DIY mechanics, fleet technicians, and small shop owners fitting an auxiliary transmission cooler or compressor aftercooler where space is limited. If you run heavier loads, tow often, operate air compressors that generate higher discharge temperatures, or want an inline option with -8AN connections, this compact aluminum unit is designed to integrate easily and provide reliable heat rejection.
