Description
The Tracerline A/C Dye for R-1234yf/Pag Syringe Injector (TP9884-BX) is a specialized syringe injector kit designed for injecting fluorescent leak detection dye into R-1234yf automotive air conditioning systems. It offers a clean and controlled method for adding dye without introducing contaminants or excess air. The kit includes an R-1234yf specific hose and quick coupler with a built-in check valve, which prevents refrigerant from flowing back into the syringe. A purge fitting on the coupler allows for the removal of air from the hose before injection, ensuring the integrity of the A/C system. This tool simplifies the process of A/C leak detection, making it more efficient for technicians to pinpoint the source of a leak.
KEY FEATURES AND BENEFITS:
- Clean Application: Prevents contaminants and excess air from entering the A/C system during dye injection.
- System-Specific Design: Includes a hose and quick coupler tailored for R-1234yf systems.
- Air Purging Function: Coupler purge fitting eliminates trapped air from the hose before injection.
- Leak Prevention: Check valve in the coupler blocks refrigerant from flowing backward into the syringe.
- Ease of Use: Simplifies leak detection for technicians with an efficient and accurate method of dye injection.
SPECIFICATIONS:
- Included in the box: Syringe Injector
- Included in the box: Hose with pressure check valve
- Included in the box: R-1234yf Quick Coupler with purge fitting
- Included in the box: Extension straws for filling the syringe
HOW TO USE:
- Prepare the Syringe: Use an extension straw to draw the required amount of fluorescent dye from its bottle into the syringe. The syringe has a clear barrel with measurement markings to help you get the right dosage.
- Connect the Coupler: Attach the R-1234yf quick coupler to the low-side service port of the vehicle’s A/C system.
- Purge the Air: Before injecting, use the purge fitting to remove any air from the hose. This is a critical step to prevent air and moisture from entering the A/C system.
- Inject the Dye: Slowly depress the syringe plunger to inject the fluorescent dye into the system. The built-in check valve will prevent refrigerant backflow.
- Circulate the Dye: Run the vehicle’s A/C system for at least 5–10 minutes to allow the dye to circulate thoroughly with the refrigerant and oil.
- Inspect for Leaks: Use a UV leak detection lamp (sold separately) to scan the A/C system. Any leaks will be highlighted by the glowing fluorescent dye.
BENEFITS OF USING TRACERLINE A/C DYE FOR R-1234YF/PAG SYRINGE INJECTOR (TP9884-BX):
- Precise Application: Syringe design ensures accurate dye dosage, reducing the risk of over- or under-application.
- Contamination-Free Injection: Purge system and check valve safeguard the A/C system from air and moisture intrusion.
