Description

Reliable Leak Detection

The Würth Basic UV Leak Detection Additive is designed to help technicians quickly and precisely locate leaks in vehicle air-conditioning systems. Once introduced into the system, the additive circulates with the refrigerant and oil, escaping wherever leaks are present. Under UV light, the fluorescent dye creates a clear and visible trace, making even the smallest leaks easy to spot.

Wide System Compatibility

This additive can be used in modern refrigerant systems (R134a, R1234yf, R744), and is also fully compatible with air-conditioning systems featuring electric compressors – common in hybrid and electric vehicles. Its compatibility with PAG and POE oils ensures broad application across workshop requirements.

Safe and Effective

Unlike some additives, the Würth UV formula has been engineered to ensure no damage to O-rings, seals, or internal system components. It integrates seamlessly with A/C oils and refrigerants, providing leak detection without compromising system performance.

Economical and Practical

One container covers up to 32 car A/C systems or 16 commercial vehicle systems, making it an efficient workshop solution for routine servicing and diagnostics.

More Information

Application Instructions

  1. Ensure the A/C system is switched off before adding the additive.
  2. Introduce the required amount of leak detection additive into the system according to the vehicle size. Passenger cars - 1/32 bottle, commercial vehicles - 1/16 bottle.
  3. Run the A/C system to allow the additive to circulate fully.
  4. Use a UV lamp to check system components, joints, and hoses for fluorescent traces indicating leaks.

Usage Notes

  • Always follow vehicle manufacturer recommendations for A/C servicing.
  • Designed for professional workshop use.
  • Store in a cool, dry place and keep sealed when not in use.
