BARTOO 1/2″ Transmission Cooler Kit

The BARTOO universal oil cooler uses a high-quality T-6061 aluminum alloy to handle demanding temperatures and pressures. It supports up to 145 PSI working pressure with 900 PSI bursting pressure and operates from -40°F to 257°F. The tube-and-fin layout helps transfer heat away from the oil efficiently as air moves through the fins, cooling the system and reducing heat-related wear.
Key features include premium material construction, strong pressure ratings, and a design that promotes air-flow across fins for effective cooling. This kit is suitable for a range of air compressors and related hydraulic or transmission cooling tasks where higher heat is generated during operation.
Belt Guard Aftercooler for 5-7.5 HP Motor

This aftercooler attaches directly to an existing belt guard with 3/4 inch female NPT fittings. It is designed to dissipate heat from hot air as it exits the compressor area, helping reduce moisture and improve air quality in the line. Its mounting simplicity makes it suitable for retrofits on older systems or compact installations where space is at a premium.
Belt Guard Aftercooler for 10 HP Motors

Designed for higher-power applications, this aftercooler uses 1 inch female NPT fittings and mounts to the belt guard. It efficiently dissipates heat from hot air, reducing moisture buildup and helping maintain consistent air quality and system performance in demanding 10 HP environments.
WEAREN 16 Pass Transmission Cooler

The WEAREN model features a universal 1/2 inch tube-and-fin arrangement with 16 passes for efficient heat transfer. Constructed from aircraft-grade aluminum, it is designed to withstand up to 145 PSI working pressure and temperatures down to -40°F and up to 257°F. With 8AN compatibility, it offers broad applicability for various air compressor and vehicle cooling needs.
WEAREN 16 Pass Transmission Oil Cooler Kit

The WEAREN oil cooler kit emphasizes an advanced 16-pass tube-and-fin structure, 8AN ports, and robust aluminum alloy construction. It is engineered to maximize heat transfer, helping maintain optimal transmission fluid temperatures, and reducing heat-related wear on transmission components in high-demand environments.
HNeekyr 16 Pass Universal Transmission Cooler

The HNeekyr cooler is a 16-pass unit built from high-grade aluminum alloy, designed for universal compatibility with 1/2 inch tubes and AN8 fittings. It delivers strong heat dissipation through a compact, durable design that supports demanding operating conditions typical of air compressors and other industrial applications. The kit is optimized for efficient air-to-fluid heat transfer with reliable performance over time.
TEMSONE 16 Pass 1/2″ Transmission Cooler

TEMSONE’s 16-pass cooler uses a 1/2-inch line design with dual-pass tube-and-fin construction to help prevent transmission fluid overheating and leaks. Made from durable aluminum, it supports a wide operating range and is suitable for use with various air compressors and related cooling obligations. It helps maintain optimal fluid temperatures, contributing to improved reliability and reduced maintenance in harsh environments.
Buying Guide: Key Considerations for Air Compressor Aftercooler Kits
- Assess compatibility: Check tube size (1/2″ and 8AN options are common), fittings (NPT or AN), and mounting space to ensure a proper fit with your compressor model and belt guard configuration.
- Material and durability: Look for aircraft-grade aluminum or premium aluminum alloys, which offer light weight, rust resistance, and strong heat tolerance for long service life.
- Heat transfer efficiency: Favor designs with multi-pass tube-and-fin configurations (e.g., 16-pass) and larger fin surfaces to maximize airflow and heat exchange, especially in high-heat environments.
- Operating pressure and temperature limits: Verify working pressure ratings (often 145 PSI or higher) and temperature ranges to ensure the cooler can withstand your system’s loads and ambient conditions.
- Installation and maintenance: Consider ease of installation, whether the kit mounts directly to guards or frames, and the availability of mounting hardware or spacers. Easy access for cleaning and inspection is a plus.
- Impact on air quality: Aftercoolers reduce moisture and heat that can compromise downstream components. If your system experiences frequent condensation, an aftercooler can help maintain dryer, cooler air.
- Space and routing considerations: Ensure adequate clearance around belts, guards, and hoses. Some coolers require a well-ventilated area to avoid heat buildup in confined spaces.
- Cost vs. benefit: While premium aluminum kits deliver strong durability, evaluate overall system needs, maintenance intervals, and the expected reduction in moisture-related issues to determine value.
- Compatibility with accessories: If your system uses AN8 or other fittings, confirm compatibility to prevent leaks or retrofit challenges.
- Warranty and support: Check manufacturer warranty terms and availability of replacement parts or spares for ongoing maintenance.
