As vehicle A/C technology continues to evolve, service technicians need tools that can keep pace with new system requirements. In particular, CO₂/R-744 is gaining attention internationally as an alternative refrigerant for next-generation vehicle A/C systems, especially as the automotive industry continues to focus on lower-GWP refrigerant options and more efficient system performance.
To support this shift, Tracerline® is excited to announce the international launch of a CO₂/R-744 leak detection solution designed for high-pressure vehicle A/C service.
This launch expands the positioning of the existing TP9815EV-P3 MINI-EZ™ Dye Cartridges by highlighting their compatibility with CO₂/R-744 high-pressure vehicle A/C systems, as well as EV/Hybrid, R-1234yf, and R-134a applications. To support safe dye injection into CO₂/R-744 systems, Tracerline® is also introducing the NEW TP32 CO₂/R-744 Hose/Coupler with Purge Fitting.
함께, TP9815EV-P3 and TP32 give technicians a dye-based leak detection solution for servicing high-pressure CO₂/R-744 A/C systems with greater confidence, accuracy, and system safety.
CO₂/R-744 Compatibility Creates a New Service Opportunity
As CO₂/R-744 adoption expands internationally, technicians will need reliable tools to diagnose leaks in these high-pressure systems. Unlike standard A/C systems, CO₂/R-744 applications require specialized equipment designed to handle higher operating pressures.
As a result, the TP9815EV-P3 MINI-EZ™ Dye Cartridges can now be positioned for use across multiple vehicle A/C system types, including:
- CO₂/R-744 high-pressure A/C systems
- EV and Hybrid A/C systems
- R-1234yf systems
- R-134a systems
Because of this versatility, technicians have one flexible UV dye solution for today’s evolving vehicle lineup.
A Complete Dye-Based Solution for High-Pressure A/C Service
Tracerline® UV dye technology helps technicians quickly and accurately locate leaks using UV light. Once the dye circulates through the A/C system, technicians can scan suspected leak areas with a UV lamp to find the exact source of the leak.
For CO₂/R-744 systems, the TP9815EV-P3 provides the compatible UV dye solution. 한편, the TP32 Hose/Coupler provides the specialized injection equipment needed for high-pressure A/C service.
함께, this combination supports a safer and more reliable dye injection process for technicians working with CO₂/R-744 systems.
Introducing the TP32 CO₂/R-744 Hose/Coupler with Purge Fitting
The new TP32 Hose/Coupler is designed for use with CO₂/R-744 vehicle A/C systems. When paired with TP9815EV-P3 MINI-EZ™ Dye Cartridges, it supports safe dye injection into high-pressure A/C systems.
Key features include:
- Meets SAE J639 for CO₂/R-744 A/C service applications
- Automatic pressure relief during disconnect
- Burst pressure: 60 MPa / 600 bar / 8,700 psi
- Durable 45.7 cm / 18 in hose for easy reach
- Purge fitting designed to support safe service procedures
By combining the TP32 Hose/Coupler with compatible Tracerline® UV dye, technicians have the right solution for diagnosing leaks in high-pressure CO₂/R-744 systems.
The Tracerline® Difference
Tracerline® has a long-standing reputation for professional-grade UV fluorescent leak detection. For decades, our TRACER® dye-based solutions have helped technicians improve diagnostic accuracy, reduce guesswork, and confirm leak locations with visual proof.
As vehicle A/C systems continue to change, Tracerline® is helping technicians stay prepared with leak detection tools designed for the next generation of refrigerant systems.
Furthermore, the launch of the TP32 CO₂/R-744 Hose/Coupler strengthens the Tracerline® product offering and creates a strong entry point into the growing CO₂ service category.
Important Safety Note
CO₂/R-744 systems operate at significantly higher pressures than traditional vehicle A/C systems. For this reason, the TP9815EV-P3 MINI-EZ™ Dye Cartridges must be used with the designated TP32 CO₂/R-744 Hose/Coupler when servicing CO₂/R-744 systems. Using non-approved hoses or injection equipment may create a serious safety risk.
Before servicing these systems, technicians should always follow proper service procedures and use equipment designed for high-pressure CO₂/R-744 applications.
Supporting the Future of Vehicle A/C Leak Detection
This international launch gives technicians a practical solution for diagnosing leaks in CO₂/R-744 high-pressure A/C systems. At the same time, it continues to support EV/Hybrid, R-1234yf, and R-134a applications.
With TP9815EV-P3 and the new TP32 Hose/Coupler, Tracerline® is helping service professionals prepare for the future of vehicle A/C leak detection.
As refrigerant technology continues to evolve globally, Tracerline® remains committed to providing trusted UV leak detection solutions that help technicians work efficiently, accurately, and safely.
